-CHANGES BETWEEN 2.9 and 2.9.1
+CHANGES BETWEEN 2.13.1 and 2.13.2 (2023-Aug-25)
+
+  I. MISCELLANEOUS
+
+  - Better support for CFF2 variation fonts.
+
+  - TrueType interpreter  version 38 (also known  as 'Infinality') has
+    been removed.
+
+  - Improved OpenVMS support.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.13.0 and 2.13.1 (2023-Jun-24)
+
+  I. MISCELLANEOUS
+
+  - New function  `FT_Get_Default_Named_Instance` to get the  index of
+    the default named instance of an OpenType Variation Font.
+
+  - A new load flag `FT_LOAD_NO_SVG` to make FreeType ignore glyphs in
+    an 'SVG ' table.
+
+  - New  function  `FT_GlyphSlot_AdjustWeight`  to  adjust  the  glyph
+    weight either  horizontally or  vertically.  This  is part  of the
+    `ftsynth.h` header file, which is  still considered to be in alpha
+    stage.
+
+  - TrueType interpreter  version 38 (also known  as 'Infinality') has
+    been deactivated; the value  of `TT_INTERPRETER_VERSION_38` is now
+    the same as `TT_INTERPRETER_VERSION_40`.
+
+  - Updated OpenVMS support.
+
+  - The  base  API  documentation  has  been  modularized  for  easier
+    handling.
+
+  - Switching named instances on and  off in Variation Fonts was buggy
+    if the design coordinates didn't change.
+
+  - `ftbench`  has a  new  command-line option  `-a`  to apply  design
+    coordinates.
+
+  - `ftview` can now flip SVG rendering on and off using the 'Z' key.
+
+  - In  `ftmulti` it  is  now possible  to toggle  the  fill rule  and
+    overlap flag  used for  rendering glyphs using  the 'F3'  and 'F4'
+    keys,  respectively.   Toggling  the anti-aliased  mode  has  been
+    changed to the 'TAB' key.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.12.1 and 2.13.0 (2023-Feb-09)
+
+  I. IMPORTANT CHANGES
+
+  - The demo program `ftinspect` has  been completely updated and much
+    enhanced.  It now  combines the functionality of  almost all other
+    graphical FreeType  demo programs into a  single application based
+    on the Qt framework.  This was Charlie Jiang's GSoC 2022 project.
+
+  - The 'COLR' v1 API is now considered as stable.
+
+      https://learn.microsoft.com/en-us/typography/opentype/spec/colr
+
+
+  II. MISCELLANEOUS
+
+  - For  OpenType  Variable Fonts,  `avar`  table  format 2.0  is  now
+    supported.  The code was contributed by Behdad Esfahbod.
+
+    Note that this is an extension supported on recent Apple platforms
+    and by HarfBuzz, but not yet in the OpenType standard!  See
+
+      https://github.com/harfbuzz/boring-expansion-spec/blob/main/avar2.md
+
+    for the specification.  To deactivate it, define the configuration
+    macro 'TT_CONFIG_OPTION_NO_BORING_EXPANSION'.
+
+  - A new API  `FT_GlyphSlot_Slant` to slant a glyph by  a given angle
+    has been added.   Note that this function is  part of `ftsynth.h`,
+    which is still considered to be in alpha stage.
+
+  - TrueType interpreter version 38  (also known as 'Infinality') that
+    was first introduced about 10 years  ago in FreeType 2.4.11 is now
+    deprecated and slated to be removed in the next version.  TrueType
+    interpreter version 40 has been FreeType's default version for six
+    years now and provides an excellent alternative.  This is the last
+    FreeType     version     with    TT_INTERPRETER_VERSION_38     and
+    TT_INTERPRETER_VERSION_40 treated differently.
+
+  - The  only  referenced  but never  documented  configuration  macro
+    `FT_CONFIG_OPTION_NO_GLYPH_NAMES` has been removed.
+
+  - The `ftbench` demo  program got a new command line  option `-e` to
+    set a charmap index.
+
+  - Specifying  a point  size is  now optional  for the  demo programs
+    `ftgrid`, `ftmulti`,  `ftstring`, and  `ftview`.  If not  given, a
+    default size is used.
+
+  - For  `ftgrid`,  `ftstring`, and  `ftview`,  option  `-e` now  also
+    accepts a numeric value to set a charmap index.
+
+  - In  `ftstring`, it  is  now  possible to  set  the displayed  text
+    interactively by pressing the 'Enter' key.
+
+  - `ftmulti` can now handle up to 16 design axes.
+
+  - To  avoid  reserved identifiers  that  are  globally defined,  the
+    auto-hinter  debugging   macros  (which  are  only   available  if
+    `FT_DEBUG_AUTOFIT` is defined)
+
+    ```
+    _af_debug_disable_horz_hints
+    _af_debug_disable_vert_hints
+    _af_debug_disable_blue_hints
+    _af_debug_hints
+    ```
+
+    have been renamed to
+
+    ```
+    af_debug_disable_horz_hints_
+    af_debug_disable_vert_hints_
+    af_debug_disable_blue_hints_
+    af_debug_hints_
+    ```
+
+  - The internal  zlib library was  updated to version  1.2.13.  Note,
+    however, that  FreeType is *not* affected  by CVE-2022-37434 since
+    it doesn't use the `inflateGetHeader` function.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.12.0 and 2.12.1 (2022-May-01)
+
+  I. IMPORTANT BUG FIXES
+
+  - Loading CFF fonts sometimes made FreeType crash (bug introduced in
+    version 2.12.0)
+
+  - Loading  a fully  hinted  TrueType glyph  a  second time  (without
+    caching) sometimes yielded different rendering results if TrueType
+    hinting was active (bug introduced in version 2.12.0).
+
+  - The generation of the pkg-config file `freetype2.pc` was broken if
+    the build was done with cmake (bug introduced in version 2.12.0).
+
+
+  II. MISCELLANEOUS
+
+  - New option `--with-librsvg` for  the `configure` script for better
+    FreeType demo support.
+
+  - The  meson  build  no  longer enforces  both  static  and  dynamic
+    versions of the library by default.
+
+  - The internal  zlib library was  updated to version  1.2.12.  Note,
+    however, that  FreeType is *not* affected  by CVE-2018-25032 since
+    it only does decompression.

+  I. IMPORTANT CHANGES
+
+  - FreeType  now   handles  OT-SVG  fonts,  to   be  controlled  with
+    `FT_CONFIG_OPTION_SVG`  configuration macro.   By default,  it can
+    only load the 'SVG ' table of an OpenType font.  However, by using
+    the `svg-hooks` property of the new 'ot-svg' module it is possible
+    to register an  external SVG rendering engine.   The FreeType demo
+    programs  have been  set  up  to use  'librsvg'  as the  rendering
+    library.
+
+    This work was Moazin Khatti's GSoC 2019 project.
+
+
+  II. MISCELLANEOUS
+
+  - The handling of fonts with an 'sbix' table has been improved.
+
+    - Corrected bitmap offsets.
+
+    - A  new tag  `FT_PARAM_TAG_IGNORE_SBIX` for  `FT_Open_Face` makes
+      FreeType ignore an 'sbix' table in a font, allowing applications
+      to access the font's outline glyphs.
+
+    - `FT_FACE_FLAG_SBIX`  and   `FT_FACE_FLAG_SBIX_OVERLAY`  together
+      with their  corresponding preprocessor macros  `FT_HAS_SBIX` and
+      `FT_HAS_SBIX_OVERLAY` enable applications to treat 'sbix' tables
+      as described in the OpenType specification.
+
+  - The internal 'zlib'  code has been updated to be  in sync with the
+    current 'zlib' version (1.2.11).
+
+  - The  previously internal  load  flag  `FT_LOAD_SBITS_ONLY` is  now
+    public.
+
+  - Some  minor improvements  of the  building systems,  in particular
+    handling of the 'zlib' library (internal vs. external).
+
+  - Support for non-desktop Universal Windows Platform.
+
+  - Various other minor bug and documentation fixes.
+
+  - The `ftdump` demo  program shows more information  for Type1 fonts
+    if option `-n` is given.
+
+  - `ftgrid` can now display embedded bitmap strikes.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.11.0 and 2.11.1 (2021-Dec-01)
+
+  I. IMPORTANT CHANGES
+
+    - Some  fields  in  the  `CID_FaceDictRec`, `CID_FaceInfoRec`, and
+      `FT_Data` structures  have been changed  from signed to unsigned
+      type,  which  better reflects  the actual usage.  It is also  an
+      additional means to protect against malformed input.
+
+
+  II. MISCELLANEOUS
+
+    - Cmake support  has been  further improved.   To do  that various
+      backward-incompatible  changes were  necessary; please  see file
+      `CMakeLists.txt` for more details.
+
+    - Since version  2.11.0, a  C99 compiler  is necessary  to compile
+      FreeType.
+
+    - The experimental  'COLR' v1 API  has been updated to  the latest
+      OpenType standard 1.9.
+
+    - The `apinames` tool got a new  option `-wV` to output an OpenVMS
+      Linker Option File.
+
+    - VMS support was updated.
+
+    - MS Visual Studio support was added to build the demo programs.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.10.4 and 2.11.0 (2021-Jul-18)
+
+  I. IMPORTANT CHANGES
+
+  - A  new rendering  module has  been  added to  create 8-bit  Signed
+    Distance Field (SDF)  bitmaps for both outline  and bitmap glyphs.
+    The new  rendering mode is called  `FT_RENDER_MODE_SDF`, the pixel
+    mode is  `FT_PIXEL_MODE_GRAY8`, and the corresponding  raster flag
+    is `FT_RASTER_FLAG_SDF`.
+
+    This work was Anuj Verma's GSoC 2020 project.
+
+  - A new, experimental API is  now available for surfacing properties
+    of 'COLR' v1  color fonts (as the name says,  this is an extension
+    to  the  'COLR' table  for  outline  color  fonts using  the  SFNT
+    container  format).   'COLR'  v1  fonts are  a  recently  proposed
+    addition to OFF and OpenType; specification work currently happens
+    in
+
+      https://github.com/googlefonts/colr-gradients-spec/
+
+    'COLR'  v1  is  expected  to   be  merged  to  OpenType;  the  ISO
+    standardisation process  for adding 'COLR'  v1 as an  amendment to
+    OFF is underway.
+
+    Functions similar  to the  already existing  'COLR' API  have been
+    added to access the corresponding data.
+
+      FT_Get_Color_Glyph_Paint
+        Retrieve the root paint for a given glyph ID.
+
+      FT_Get_Paint_Layers
+        Access the layers of a `PaintColrLayers` table.
+
+      FT_Get_Colorline_Stops
+        Retrieve the  'color stops' on a  color line.  As an  input, a
+        color stop iterator gets used, which in turn is retrieved from
+        a paint.
+
+      FT_Get_Paint
+        Dereference  an  `FT_OpaquePaint`   object  and  retrieve  the
+        corresponding `FT_COLR_Paint`  object, which  contains details
+        on how to draw the respective 'COLR' v1 `Paint` table.
+
+
+  II. MISCELLANEOUS
+
+  - FreeType has moved its infrastructure to
+
+      https://gitlab.freedesktop.org/freetype
+
+    A  side  effect  is  that  the git  repositories  are  now  called
+    `freetype.git` and  `freetype-demos.git`, which by  default expand
+    to the directories  `freetype` and `freetype-demos`, respectively.
+    The documentation has been updated accordingly.
+
+    FreeType's Savannah  repositories will stay; they  are now mirrors
+    of the 'freedesktop.org' repositories.
+
+  - A  new  function  `FT_Get_Transform`  returns  the  values set  by
+    `FT_Set_Transform`.
+
+  - A  new configuration  macro `FT_DEBUG_LOGGING`  is available.   It
+    provides extended debugging capabilities for FreeType, for example
+    showing a time stamp or displaying the component a tracing message
+    comes from.  See file `docs/DEBUG` for more information.
+
+    This work was Priyesh Kumar's GSoC 2020 project.
+
+  - The legacy Type 1 and CFF  engines are further demoted due to lack
+    of CFF2 charstring support.  You now need to use `FT_Property_Set`
+    to  enable  them  besides  the  `T1_CONFIG_OPTION_OLD_ENGINE`  and
+    `CFF_CONFIG_OPTION_OLD_ENGINE` options, respectively.
+
+  - The experimental 'warp' mode (AF_CONFIG_OPTION_USE_WARPER) for the
+    auto-hinter has been removed.
+
+  - The smooth rasterizer performance has been improved by >10%.  Note
+    that  due to  necessary code  changes there  might be  very subtle
+    differences  in  rendering.  They  are  not  visible by  the  eye,
+    however.
+
+  - PCF bitmap fonts compressed with LZW (these are usually files with
+    the extension `.pcf.Z`) are now handled correctly.
+
+  - Improved  Meson  build  files,  including  support  to  build  the
+    FreeType demo programs.
+
+  - A new demo program `ftsdf` is available to display Signed Distance
+    Fields of glyphs.
+
+  - The `ftlint` demo program has been  extended to do more testing of
+    its input.  In particular, it  can display horizontal and vertical
+    acutances  for quality  assessment,  together  with computing  MD5
+    checksums of rendered glyphs.
+
+    [The acutance measures  how sharply the pixel  coverage changes at
+     glyph edges.  For monochrome bitmaps,  it is always 2.0 in either
+     X or  Y direction.  For  anti-aliased bitmaps, it depends  on the
+     hinting and the shape of a glyph and might approach or even reach
+     value 2.0  for glyphs like 'I',  'L', '+', '-', or  '=', while it
+     might be lower for glyphs like 'O', 'S', or 'W'.]
+
+  - The `ttdebug`  demo program didn't show  changed point coordinates
+    (bug introduced in version 2.10.3).
+
+  - It is now possible to adjust the axis increment for variable fonts
+    in the `ftmulti` demo program.
+
+  - It is now possible to change  the hinting engine in the `ftstring`
+    demo program.
+
+  - The graphical demo programs work  better now in native color depth
+    on win32 and x11.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.10.3 and 2.10.4 (2020-Oct-20)
+
+  I. IMPORTANT BUG FIXES
+
+  - A heap buffer overflow has been found  in the handling of embedded
+    PNG bitmaps, introduced in FreeType version 2.6.
+
+      https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-15999
+
+    If you  use option  FT_CONFIG_OPTION_USE_PNG  you  should  upgrade
+    immediately.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.10.2 and 2.10.3 (2020-Oct-10)
+
+  I. IMPORTANT CHANGES
+
+  - New flag `FT_OUTLINE_OVERLAP'.  If set, make the smooth rasterizer
+    do  4x4 oversampling  to  mitigate artifacts  in pixels  partially
+    covered  by  overlapping  contours.    Note  that  this  at  least
+    quadruples the rendering time.
+
+    If  a  glyph  in  a  TrueType font  has  the  `OVERLAP_SIMPLE'  or
+    `OVERLAP_COMPOUND'  bit set,  FreeType automatically  selects this
+    rendering mode.
+
+
+  II. MISCELLANEOUS
+
+  - Using the  arcane method of  including FreeType header  files with
+    macros like  `FT_FREETYPE_H' is no longer  mandatory (but retained
+    as an optional feature for backward compatibility).
+
+  - Support for  building the library  with Meson.  Building  the demo
+    programs with Meson will follow in a forthcoming release.
+
+  - Minor improvements to the B/W rasterizer.
+
+  - Auto-hinter support for Medefaidrin script.
+
+  - Fix various  memory leaks (mainly  for CFF) and other  issues that
+    might cause crashes in rare circumstances.
+
+  - Jam support has been removed.
+
+  - In  `ftview', custom  LCD  filter values  are  now normalized  and
+    balanced.  Unorthodox filters are still available through the `-L'
+    command line option.
+
+  - The GUI demo programs can now be resized.
+
+  - Demo programs that accept command  line option `-k' can now handle
+    function keys, too.  The  corresponding character codes start with
+    0xF1.  As  an example, the  POSIX shell syntax (accepted  by bash,
+    ksh, and zsh)
+
+      -k $'\xF3q'
+
+    emulates the pressing of function key `F3' followed by key `q'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.10.1 and 2.10.2 (2020-May-09)
+
+  I. IMPORTANT CHANGES
+
+  - Support  of  WOFF2  fonts.   This  code  contribution  was  Nikhil
+    Ramakrishnan's GSoC 2019 project.
+
+
+  II. MISCELLANEOUS
+
+  - Function  `FT_Get_Var_Axis_Flags' returned random data for  Type 1
+    MM fonts.
+
+  - Type 1 fonts with non-integer metrics are now supported by the new
+    (CFF) engine introduced in FreeType 2.9.
+
+  - Drop  support  for Python 2 in Freetype's API reference  generator
+    `docwriter'  (Python >= 3.5 is required for targets  `make refdoc'
+    and `make refdoc-venv').
+
+  - Auto-hinter support for Hanifi Rohingya.
+
+  - Document the `FT2_KEEP_ALIVE' debugging environment variable.
+
+  - The Visual C++ (and Visual C)  project files for Windows builds no
+    longer generate libraries that contain the FreeType version in its
+    filenames.   Instead,  a  resource  file gets  used  to  make  the
+    libraries contain the corresponding information.
+
+  - The next release will remove Jam build support.
+
+  - The  `ftbench'  demo  program  has  a new  test  for  testing  the
+    `FT_Glyph_Stroke' functionality.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.10.0 and 2.10.1 (2019-Jul-01)
+
+  I. IMPORTANT BUG FIXES
+
+  - The bytecode hinting of OpenType variation fonts was flawed, since
+    the data in the `CVAR' table wasn't correctly applied.
+
+
+  II. MISCELLANEOUS
+
+  - Auto-hinter support for Mongolian.
+
+  - For distribution,  `.tar.bz2' packages are replaced with `.tar.xz'
+    bundles.
+
+  - The handling of  the default character in PCF fonts as  introduced
+    in version 2.10.0 was partially broken, causing premature abortion
+    of charmap iteration for many fonts.
+
+  - If  `FT_Set_Named_Instance' was  called  with  the same  arguments
+    twice in a row, the function  returned an incorrect error code the
+    second time.
+
+  - Direct   rendering   using  FT_RASTER_FLAG_DIRECT   crashed   (bug
+    introduced in version 2.10.0).
+
+  - Increased  precision  while  computing  OpenType  font   variation
+    instances.
+
+  - The  flattening  algorithm of  cubic  Bezier  curves was  slightly
+    changed to make  it faster.  This can cause  very subtle rendering
+    changes, which aren't noticeable by the eye, however.
+
+  - The  auto-hinter  now  disables hinting  if there  are blue  zones
+    defined for a `style' (i.e., a certain combination of a script and
+    its related typographic features) but the font doesn't contain any
+    characters needed to set up at least one blue zone.
+
+  - The `ftmulti' demo program now  supports multiple hidden axes with
+    the same name tag.
+
+  - `ftview', `ftstring', and `ftgrid' got  a `-k' command line option
+    to emulate a sequence of keystrokes at start-up.
+
+  - `ftview', `ftstring', and `ftgrid' now support screen dumping to a
+    PNG file.
+
+  - The bytecode debugger, `ttdebug',  now supports variation TrueType
+    fonts; a variation font instance can be selected with the new `-d'
+    command line option.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.9.1 and 2.10.0 (2019-Mar-15)
+
+  I. IMPORTANT CHANGES
+
+    - A bunch  of new functions has  been added to access  and process
+      COLR/CPAL data of OpenType fonts with color-layered glyphs.
+
+        FT_Palette_Data_Get
+          Retrieve color palette data.
+        FT_Palette_Select
+          Select and activate a color palette for color-layered
+          glyphs.
+        FT_Palette_Set_Foreground_Color
+          Set text foreground color for palette index 0xFFFF.
+
+        FT_Get_Color_Glyph_Layer
+          Get color layers for a given glyph (using an interator
+          object).
+
+        FT_Bitmap_Blend
+          Blend one bitmap onto another with a given color.
+
+    - An   experimental  feature   is   the  new   behaviour  of   the
+      `FT_LOAD_COLOR' load  flag for color-layered  glyphs: Internally
+      it  sets a  flag so  that  if `FT_Render_Glyph'  is called  with
+      `FT_RENDER_MODE_NORMAL'      (or       `FT_Load_Glyph'      with
+      `FT_LOAD_RENDER'), a default blending  of the color glyph layers
+      will happen automatically for convenience.
+
+    - As  a   GSoC  2018   project,  Nikhil   Ramakrishnan  completely
+      overhauled and modernized the API reference.
+
+
+  II. MISCELLANEOUS
+
+    - The  logic for  computing  the global  ascender, descender,  and
+      height  of  OpenType  fonts   has  been  slightly  adjusted  for
+      consistency.
+
+      . If the `useTypoMetrics' flag (i.e., bit 7 in the `fsSelection'
+        field) in the  `OS/2' table is set, use the  `sTypo' fields in
+        `OS/2' unconditionally.
+      . Otherwise use  the metrics data from the `hhea'  table (if not
+        zero).
+      . Otherwise use the `sTypo' fields from the `OS/2' table (if not
+        zero).
+      . Otherwise use the `usWin' data from the `OS/2' table as a last
+        resort.
+
+      Variable fonts will apply the `MVAR' deltas to whichever metrics
+      were picked.
+
+    - `TT_Set_MM_Blend' could  fail if  call repeatedly with  the same
+      arguments.
+
+    - The precision  of handling  deltas in  Variation Fonts  has been
+      increased.  The  problem did only show  up with multidimensional
+      designspaces.
+
+    - New function `FT_Library_SetLcdGeometry' to  set up the geometry
+      of LCD subpixels.
+
+    - FreeType now uses the `defaultChar' property of PCF fonts to set
+      the  glyph for  the undefined  character  at glyph  index 0  (as
+      FreeType already does for all other supported font formats).  As
+      a consequence,  the order of  glyphs of  a PCF font  if accessed
+      with  FreeType  can  be   different  now  compared  to  previous
+      versions.
+
+      This change doesn't affect PCF font access with cmaps.
+
+    - `FT_Select_Charmap' has  been changed  to allow  parameter value
+      `FT_ENCODING_NONE', which is valid for BDF, PCF, and Windows FNT
+      formats to  access built-in cmaps  that don't have  a predefined
+      `FT_Encoding' value.
+
+    - A previously  reserved field in the  `FT_GlyphSlotRec' structure
+      now holds the glyph index.
+
+    - On Win32 platforms,  the use of `_DLL' to build  the library has
+      been replaced with `DLL_EXPORT' and `DLL_IMPORT'.
+
+    - The usual round  of fuzzer bug fixes to  better reject malformed
+      fonts.
+
+    - `FT_Outline_New_Internal'  and  `FT_Outline_Done_Internal'  have
+      been removed.  These two functions were public by oversight only
+      and were never documented.
+
+    - A new  function `FT_Error_String' returns descriptions  of error
+      codes if  configuration macro  FT_CONFIG_OPTION_ERROR_STRINGS is
+      defined.
+
+    - `FT_Set_MM_WeightVector'  and  `FT_Get_MM_WeightVector' are  new
+      functions limited to Adobe MultiMaster fonts to directly set and
+      get the weight vector.
+
+    - Support for Position Independent Code as needed by  systems that
+      prohibit  automatic  address  fixups,  such  as BREW,  has  been
+      removed.  [Compilation with modern compilers that use flags like
+      `-fPIC' or `-fPIE' is not affected.]
+
+    - The  `ftdump' demo  program has  new  options `-c'  and `-C'  to
+      display charmaps  in compact and detailed  format, respectively.
+      Option `-V' has been removed.
+
+    - The `ftview', `ftstring',  and `ftgrid' demo programs  use a new
+      command line option `-d' to  specify the program window's width,
+      height, and color depth.
+
+    - The `ftview' demo program now  displays red boxes for zero-width
+      glyphs.
+
+    - `ftglyph'   has   limited   support  to   display   fonts   with
+      color-layered glyphs.  This will be improved later on.
+
+    - `ftgrid' can now display bitmap fonts also.
+
+    - The `ttdebug'  demo program has  a new  option `-f' to  select a
+      member of a TrueType collection (TTC).
+
+    - Other various improvements to the demo programs.

+

+    `Keep alive' means that freed  blocks aren't released to the heap.
+    This is  useful to detect  double-frees or weird  heap corruption,
+    reporting the source code location  of the original allocation and
+    deallocation  in case  of a  problem.   It uses  large amounts  of

+
+
+IV. Additional Capabilities with `FT_DEBUG_LOGGING'
+---------------------------------------------------
+
+If `FT_DEBUG_LOGGING' is  defined, four APIs are  available to provide
+additional debugging support.  Use
+
+  #include <freetype/ftlogging.h>
+
+to access them.
+
+  FT_Trace_Set_Level( const char*  level )
+
+    By  default,  FreeType   uses  the  tracing  levels   set  in  the
+    `FT2_DEBUG' environment  variable.  Use this function  to override
+    the value with `level'.  Use value `NULL' to disable tracing.
+
+  FT_Trace_Set_Default_Level( void )
+
+    Reset the tracing levels to the default value, i.e., the value of
+    the `FT2_DEBUG' environment variable or no tracing if not set.
+
+  FT_Set_Log_Handler( ft_custom_log_handler  handler )
+
+    Use `handler' as a custom handler for formatting tracing and error
+    messages.  The  `ft_custom_log_handler' typedef has  the following
+    prototype.
+
+      void
+      (*ft_custom_log_handler)( const char*  ft_component,
+                                const char*  fmt,
+                                va_list      args );
+
+   `ft_component' is the current component like `ttload', `fmt' is the
+   first argument  of `FT_TRACE' or  `FT_ERROR', and `args'  holds the
+   remaining arguments.
+
+  FT_Set_Default_Log_Handler( void )
+
+    Reset the log handler to the default version.
+

-The  FreeType 2  font  engine is  copyrighted  work and  cannot be  used
-legally  without a  software license.   In  order to  make this  project
-usable  to a vast  majority of  developers, we  distribute it  under two
-mutually exclusive open-source licenses.
-
-This means  that *you* must choose  *one* of the  two licenses described
-below, then obey  all its terms and conditions when  using FreeType 2 in
-any of your projects or products.
-
-  - The FreeType License, found in  the file `FTL.TXT', which is similar
-    to the original BSD license *with* an advertising clause that forces
-    you  to  explicitly cite  the  FreeType  project  in your  product's
-    documentation.  All  details are in the license  file.  This license
-    is  suited  to products  which  don't  use  the GNU  General  Public
-    License.
-
-    Note that  this license  is  compatible  to the  GNU General  Public
-    License version 3, but not version 2.
-
-  - The GNU General Public License version 2, found in  `GPLv2.TXT' (any
-    later version can be used  also), for programs which already use the
-    GPL.  Note  that the  FTL is  incompatible  with  GPLv2 due  to  its
-    advertisement clause.
-
-The contributed BDF and PCF drivers  come with a license similar to that
-of the X Window System.  It is compatible to the above two licenses (see
-file src/bdf/README and  src/pcf/README).  The same holds  for the files
-`fthash.c' and  `fthash.h'; their  code was  part of  the BDF  driver in
-earlier FreeType versions.
-
-The gzip module uses the zlib license (see src/gzip/zlib.h) which too is
-compatible to the above two licenses.
-
-The MD5 checksum support (only used for debugging in development builds)
-is in the public domain.

+   *   What FreeType is and isn't
+   *
+   * @description:
+   *   FreeType is a library that provides access to glyphs in font files.  It
+   *   scales the glyph images and their metrics to a requested size, and it
+   *   rasterizes the glyph images to produce pixel or subpixel alpha coverage
+   *   bitmaps.
+   *
+   *   Note that FreeType is _not_ a text layout engine.  You have to use
+   *   higher-level libraries like HarfBuzz, Pango, or ICU for that.
+   *
+   *   Note also that FreeType does _not_ perform alpha blending or
+   *   compositing the resulting bitmaps or pixmaps by itself.  Use your
+   *   favourite graphics library (for example, Cairo or Skia) to further
+   *   process FreeType's output.

+   * @enum:
+   *   FT_Encoding
+   *
+   * @description:
+   *   An enumeration to specify character sets supported by charmaps.  Used
+   *   in the @FT_Select_Charmap API function.
+   *
+   * @note:
+   *   Despite the name, this enumeration lists specific character
+   *   repertoires (i.e., charsets), and not text encoding methods (e.g.,
+   *   UTF-8, UTF-16, etc.).
+   *
+   *   Other encodings might be defined in the future.
+   *
+   * @values:
+   *   FT_ENCODING_NONE ::
+   *     The encoding value~0 is reserved for all formats except BDF, PCF,
+   *     and Windows FNT; see below for more information.
+   *
+   *   FT_ENCODING_UNICODE ::
+   *     The Unicode character set.  This value covers all versions of the
+   *     Unicode repertoire, including ASCII and Latin-1.  Most fonts include
+   *     a Unicode charmap, but not all of them.
+   *
+   *     For example, if you want to access Unicode value U+1F028 (and the
+   *     font contains it), use value 0x1F028 as the input value for
+   *     @FT_Get_Char_Index.
+   *
+   *   FT_ENCODING_MS_SYMBOL ::
+   *     Microsoft Symbol encoding, used to encode mathematical symbols and
+   *     wingdings.  For more information, see
+   *     'https://www.microsoft.com/typography/otspec/recom.htm#non-standard-symbol-fonts',
+   *     'http://www.kostis.net/charsets/symbol.htm', and
+   *     'http://www.kostis.net/charsets/wingding.htm'.
+   *
+   *     This encoding uses character codes from the PUA (Private Unicode
+   *     Area) in the range U+F020-U+F0FF.
+   *
+   *   FT_ENCODING_SJIS ::
+   *     Shift JIS encoding for Japanese.  More info at
+   *     'https://en.wikipedia.org/wiki/Shift_JIS'.  See note on multi-byte
+   *     encodings below.
+   *
+   *   FT_ENCODING_PRC ::
+   *     Corresponds to encoding systems mainly for Simplified Chinese as
+   *     used in People's Republic of China (PRC).  The encoding layout is
+   *     based on GB~2312 and its supersets GBK and GB~18030.
+   *
+   *   FT_ENCODING_BIG5 ::
+   *     Corresponds to an encoding system for Traditional Chinese as used in
+   *     Taiwan and Hong Kong.
+   *
+   *   FT_ENCODING_WANSUNG ::
+   *     Corresponds to the Korean encoding system known as Extended Wansung
+   *     (MS Windows code page 949).  For more information see
+   *     'https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WindowsBestFit/bestfit949.txt'.
+   *
+   *   FT_ENCODING_JOHAB ::
+   *     The Korean standard character set (KS~C 5601-1992), which
+   *     corresponds to MS Windows code page 1361.  This character set
+   *     includes all possible Hangul character combinations.
+   *
+   *   FT_ENCODING_ADOBE_LATIN_1 ::
+   *     Corresponds to a Latin-1 encoding as defined in a Type~1 PostScript
+   *     font.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_STANDARD ::
+   *     Adobe Standard encoding, as found in Type~1, CFF, and OpenType/CFF
+   *     fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_EXPERT ::
+   *     Adobe Expert encoding, as found in Type~1, CFF, and OpenType/CFF
+   *     fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_ADOBE_CUSTOM ::
+   *     Corresponds to a custom encoding, as found in Type~1, CFF, and
+   *     OpenType/CFF fonts.  It is limited to 256 character codes.
+   *
+   *   FT_ENCODING_APPLE_ROMAN ::
+   *     Apple roman encoding.  Many TrueType and OpenType fonts contain a
+   *     charmap for this 8-bit encoding, since older versions of Mac OS are
+   *     able to use it.
+   *
+   *   FT_ENCODING_OLD_LATIN_2 ::
+   *     This value is deprecated and was neither used nor reported by
+   *     FreeType.  Don't use or test for it.
+   *
+   *   FT_ENCODING_MS_SJIS ::
+   *     Same as FT_ENCODING_SJIS.  Deprecated.
+   *
+   *   FT_ENCODING_MS_GB2312 ::
+   *     Same as FT_ENCODING_PRC.  Deprecated.
+   *
+   *   FT_ENCODING_MS_BIG5 ::
+   *     Same as FT_ENCODING_BIG5.  Deprecated.
+   *
+   *   FT_ENCODING_MS_WANSUNG ::
+   *     Same as FT_ENCODING_WANSUNG.  Deprecated.
+   *
+   *   FT_ENCODING_MS_JOHAB ::
+   *     Same as FT_ENCODING_JOHAB.  Deprecated.
+   *
+   * @note:
+   *   When loading a font, FreeType makes a Unicode charmap active if
+   *   possible (either if the font provides such a charmap, or if FreeType
+   *   can synthesize one from PostScript glyph name dictionaries; in either
+   *   case, the charmap is tagged with `FT_ENCODING_UNICODE`).  If such a
+   *   charmap is synthesized, it is placed at the first position of the
+   *   charmap array.
+   *
+   *   All other encodings are considered legacy and tagged only if
+   *   explicitly defined in the font file.  Otherwise, `FT_ENCODING_NONE` is
+   *   used.
+   *
+   *   `FT_ENCODING_NONE` is set by the BDF and PCF drivers if the charmap is
+   *   neither Unicode nor ISO-8859-1 (otherwise it is set to
+   *   `FT_ENCODING_UNICODE`).  Use @FT_Get_BDF_Charset_ID to find out which
+   *   encoding is really present.  If, for example, the `cs_registry` field
+   *   is 'KOI8' and the `cs_encoding` field is 'R', the font is encoded in
+   *   KOI8-R.
+   *
+   *   `FT_ENCODING_NONE` is always set (with a single exception) by the
+   *   winfonts driver.  Use @FT_Get_WinFNT_Header and examine the `charset`
+   *   field of the @FT_WinFNT_HeaderRec structure to find out which encoding
+   *   is really present.  For example, @FT_WinFNT_ID_CP1251 (204) means
+   *   Windows code page 1251 (for Russian).
+   *
+   *   `FT_ENCODING_NONE` is set if `platform_id` is @TT_PLATFORM_MACINTOSH
+   *   and `encoding_id` is not `TT_MAC_ID_ROMAN` (otherwise it is set to
+   *   `FT_ENCODING_APPLE_ROMAN`).
+   *
+   *   If `platform_id` is @TT_PLATFORM_MACINTOSH, use the function
+   *   @FT_Get_CMap_Language_ID to query the Mac language ID that may be
+   *   needed to be able to distinguish Apple encoding variants.  See
+   *
+   *     https://www.unicode.org/Public/MAPPINGS/VENDORS/APPLE/Readme.txt
+   *
+   *   to get an idea how to do that.  Basically, if the language ID is~0,
+   *   don't use it, otherwise subtract 1 from the language ID.  Then examine
+   *   `encoding_id`.  If, for example, `encoding_id` is `TT_MAC_ID_ROMAN`
+   *   and the language ID (minus~1) is `TT_MAC_LANGID_GREEK`, it is the
+   *   Greek encoding, not Roman.  `TT_MAC_ID_ARABIC` with

+   * @struct:
+   *   FT_FaceRec
+   *
+   * @description:
+   *   FreeType root face class structure.  A face object models a typeface
+   *   in a font file.
+   *
+   * @fields:
+   *   num_faces ::
+   *     The number of faces in the font file.  Some font formats can have
+   *     multiple faces in a single font file.
+   *
+   *   face_index ::
+   *     This field holds two different values.  Bits 0-15 are the index of
+   *     the face in the font file (starting with value~0).  They are set
+   *     to~0 if there is only one face in the font file.
+   *
+   *     [Since 2.6.1] Bits 16-30 are relevant to GX and OpenType variation
+   *     fonts only, holding the named instance index for the current face
+   *     index (starting with value~1; value~0 indicates font access without
+   *     a named instance).  For non-variation fonts, bits 16-30 are ignored.
+   *     If we have the third named instance of face~4, say, `face_index` is
+   *     set to 0x00030004.
+   *
+   *     Bit 31 is always zero (that is, `face_index` is always a positive
+   *     value).
+   *
+   *     [Since 2.9] Changing the design coordinates with
+   *     @FT_Set_Var_Design_Coordinates or @FT_Set_Var_Blend_Coordinates does
+   *     not influence the named instance index value (only
+   *     @FT_Set_Named_Instance does that).
+   *
+   *   face_flags ::
+   *     A set of bit flags that give important information about the face;
+   *     see @FT_FACE_FLAG_XXX for the details.
+   *
+   *   style_flags ::
+   *     The lower 16~bits contain a set of bit flags indicating the style of
+   *     the face; see @FT_STYLE_FLAG_XXX for the details.
+   *
+   *     [Since 2.6.1] Bits 16-30 hold the number of named instances
+   *     available for the current face if we have a GX or OpenType variation
+   *     (sub)font.  Bit 31 is always zero (that is, `style_flags` is always
+   *     a positive value).  Note that a variation font has always at least
+   *     one named instance, namely the default instance.
+   *
+   *   num_glyphs ::
+   *     The number of glyphs in the face.  If the face is scalable and has
+   *     sbits (see `num_fixed_sizes`), it is set to the number of outline
+   *     glyphs.
+   *
+   *     For CID-keyed fonts (not in an SFNT wrapper) this value gives the
+   *     highest CID used in the font.
+   *
+   *   family_name ::
+   *     The face's family name.  This is an ASCII string, usually in
+   *     English, that describes the typeface's family (like 'Times New
+   *     Roman', 'Bodoni', 'Garamond', etc).  This is a least common
+   *     denominator used to list fonts.  Some formats (TrueType & OpenType)
+   *     provide localized and Unicode versions of this string.  Applications
+   *     should use the format-specific interface to access them.  Can be
+   *     `NULL` (e.g., in fonts embedded in a PDF file).
+   *
+   *     In case the font doesn't provide a specific family name entry,
+   *     FreeType tries to synthesize one, deriving it from other name
+   *     entries.
+   *
+   *   style_name ::
+   *     The face's style name.  This is an ASCII string, usually in English,
+   *     that describes the typeface's style (like 'Italic', 'Bold',
+   *     'Condensed', etc).  Not all font formats provide a style name, so
+   *     this field is optional, and can be set to `NULL`.  As for
+   *     `family_name`, some formats provide localized and Unicode versions
+   *     of this string.  Applications should use the format-specific
+   *     interface to access them.
+   *
+   *   num_fixed_sizes ::
+   *     The number of bitmap strikes in the face.  Even if the face is
+   *     scalable, there might still be bitmap strikes, which are called
+   *     'sbits' in that case.
+   *
+   *   available_sizes ::
+   *     An array of @FT_Bitmap_Size for all bitmap strikes in the face.  It
+   *     is set to `NULL` if there is no bitmap strike.
+   *
+   *     Note that FreeType tries to sanitize the strike data since they are
+   *     sometimes sloppy or incorrect, but this can easily fail.
+   *
+   *   num_charmaps ::
+   *     The number of charmaps in the face.
+   *
+   *   charmaps ::
+   *     An array of the charmaps of the face.
+   *
+   *   generic ::
+   *     A field reserved for client uses.  See the @FT_Generic type
+   *     description.
+   *
+   *   bbox ::
+   *     The font bounding box.  Coordinates are expressed in font units (see
+   *     `units_per_EM`).  The box is large enough to contain any glyph from
+   *     the font.  Thus, `bbox.yMax` can be seen as the 'maximum ascender',
+   *     and `bbox.yMin` as the 'minimum descender'.  Only relevant for
+   *     scalable formats.
+   *
+   *     Note that the bounding box might be off by (at least) one pixel for
+   *     hinted fonts.  See @FT_Size_Metrics for further discussion.
+   *
+   *     Note that the bounding box does not vary in OpenType variation fonts
+   *     and should only be used in relation to the default instance.
+   *
+   *   units_per_EM ::
+   *     The number of font units per EM square for this face.  This is
+   *     typically 2048 for TrueType fonts, and 1000 for Type~1 fonts.  Only
+   *     relevant for scalable formats.
+   *
+   *   ascender ::
+   *     The typographic ascender of the face, expressed in font units.  For
+   *     font formats not having this information, it is set to `bbox.yMax`.
+   *     Only relevant for scalable formats.
+   *
+   *   descender ::
+   *     The typographic descender of the face, expressed in font units.  For
+   *     font formats not having this information, it is set to `bbox.yMin`.
+   *     Note that this field is negative for values below the baseline.
+   *     Only relevant for scalable formats.
+   *
+   *   height ::
+   *     This value is the vertical distance between two consecutive
+   *     baselines, expressed in font units.  It is always positive.  Only
+   *     relevant for scalable formats.
+   *
+   *     If you want the global glyph height, use `ascender - descender`.
+   *
+   *   max_advance_width ::
+   *     The maximum advance width, in font units, for all glyphs in this
+   *     face.  This can be used to make word wrapping computations faster.
+   *     Only relevant for scalable formats.
+   *
+   *   max_advance_height ::
+   *     The maximum advance height, in font units, for all glyphs in this
+   *     face.  This is only relevant for vertical layouts, and is set to
+   *     `height` for fonts that do not provide vertical metrics.  Only
+   *     relevant for scalable formats.
+   *
+   *   underline_position ::
+   *     The position, in font units, of the underline line for this face.
+   *     It is the center of the underlining stem.  Only relevant for
+   *     scalable formats.
+   *
+   *   underline_thickness ::
+   *     The thickness, in font units, of the underline for this face.  Only
+   *     relevant for scalable formats.
+   *
+   *   glyph ::
+   *     The face's associated glyph slot(s).
+   *
+   *   size ::
+   *     The current active size for this face.
+   *
+   *   charmap ::
+   *     The current active charmap for this face.
+   *
+   * @note:
+   *   Fields may be changed after a call to @FT_Attach_File or
+   *   @FT_Attach_Stream.
+   *
+   *   For an OpenType variation font, the values of the following fields can
+   *   change after a call to @FT_Set_Var_Design_Coordinates (and friends) if
+   *   the font contains an 'MVAR' table: `ascender`, `descender`, `height`,
+   *   `underline_position`, and `underline_thickness`.
+   *
+   *   Especially for TrueType fonts see also the documentation for
+   *   @FT_Size_Metrics.

+   * @description:
+   *   A list of bit flags used in the `face_flags` field of the @FT_FaceRec
+   *   structure.  They inform client applications of properties of the
+   *   corresponding face.
+   *
+   * @values:
+   *   FT_FACE_FLAG_SCALABLE ::
+   *     The face contains outline glyphs.  Note that a face can contain
+   *     bitmap strikes also, i.e., a face can have both this flag and
+   *     @FT_FACE_FLAG_FIXED_SIZES set.
+   *
+   *   FT_FACE_FLAG_FIXED_SIZES ::
+   *     The face contains bitmap strikes.  See also the `num_fixed_sizes`
+   *     and `available_sizes` fields of @FT_FaceRec.
+   *
+   *   FT_FACE_FLAG_FIXED_WIDTH ::
+   *     The face contains fixed-width characters (like Courier, Lucida,
+   *     MonoType, etc.).
+   *
+   *   FT_FACE_FLAG_SFNT ::
+   *     The face uses the SFNT storage scheme.  For now, this means TrueType
+   *     and OpenType.
+   *
+   *   FT_FACE_FLAG_HORIZONTAL ::
+   *     The face contains horizontal glyph metrics.  This should be set for
+   *     all common formats.
+   *
+   *   FT_FACE_FLAG_VERTICAL ::
+   *     The face contains vertical glyph metrics.  This is only available in
+   *     some formats, not all of them.
+   *
+   *   FT_FACE_FLAG_KERNING ::
+   *     The face contains kerning information.  If set, the kerning distance
+   *     can be retrieved using the function @FT_Get_Kerning.  Otherwise the
+   *     function always returns the vector (0,0).  Note that FreeType
+   *     doesn't handle kerning data from the SFNT 'GPOS' table (as present
+   *     in many OpenType fonts).
+   *
+   *   FT_FACE_FLAG_FAST_GLYPHS ::
+   *     THIS FLAG IS DEPRECATED.  DO NOT USE OR TEST IT.
+   *
+   *   FT_FACE_FLAG_MULTIPLE_MASTERS ::
+   *     The face contains multiple masters and is capable of interpolating
+   *     between them.  Supported formats are Adobe MM, TrueType GX, and
+   *     OpenType variation fonts.
+   *
+   *     See section @multiple_masters for API details.
+   *
+   *   FT_FACE_FLAG_GLYPH_NAMES ::
+   *     The face contains glyph names, which can be retrieved using
+   *     @FT_Get_Glyph_Name.  Note that some TrueType fonts contain broken
+   *     glyph name tables.  Use the function @FT_Has_PS_Glyph_Names when
+   *     needed.
+   *
+   *   FT_FACE_FLAG_EXTERNAL_STREAM ::
+   *     Used internally by FreeType to indicate that a face's stream was
+   *     provided by the client application and should not be destroyed when
+   *     @FT_Done_Face is called.  Don't read or test this flag.
+   *
+   *   FT_FACE_FLAG_HINTER ::
+   *     The font driver has a hinting machine of its own.  For example, with
+   *     TrueType fonts, it makes sense to use data from the SFNT 'gasp'
+   *     table only if the native TrueType hinting engine (with the bytecode
+   *     interpreter) is available and active.
+   *
+   *   FT_FACE_FLAG_CID_KEYED ::
+   *     The face is CID-keyed.  In that case, the face is not accessed by
+   *     glyph indices but by CID values.  For subsetted CID-keyed fonts this
+   *     has the consequence that not all index values are a valid argument
+   *     to @FT_Load_Glyph.  Only the CID values for which corresponding
+   *     glyphs in the subsetted font exist make `FT_Load_Glyph` return
+   *     successfully; in all other cases you get an
+   *     `FT_Err_Invalid_Argument` error.
+   *
+   *     Note that CID-keyed fonts that are in an SFNT wrapper (that is, all
+   *     OpenType/CFF fonts) don't have this flag set since the glyphs are
+   *     accessed in the normal way (using contiguous indices); the
+   *     'CID-ness' isn't visible to the application.
+   *
+   *   FT_FACE_FLAG_TRICKY ::
+   *     The face is 'tricky', that is, it always needs the font format's
+   *     native hinting engine to get a reasonable result.  A typical example
+   *     is the old Chinese font `mingli.ttf` (but not `mingliu.ttc`) that
+   *     uses TrueType bytecode instructions to move and scale all of its
+   *     subglyphs.
+   *
+   *     It is not possible to auto-hint such fonts using
+   *     @FT_LOAD_FORCE_AUTOHINT; it will also ignore @FT_LOAD_NO_HINTING.
+   *     You have to set both @FT_LOAD_NO_HINTING and @FT_LOAD_NO_AUTOHINT to
+   *     really disable hinting; however, you probably never want this except
+   *     for demonstration purposes.
+   *
+   *     Currently, there are about a dozen TrueType fonts in the list of
+   *     tricky fonts; they are hard-coded in file `ttobjs.c`.
+   *
+   *   FT_FACE_FLAG_COLOR ::
+   *     [Since 2.5.1] The face has color glyph tables.  See @FT_LOAD_COLOR
+   *     for more information.
+   *
+   *   FT_FACE_FLAG_VARIATION ::
+   *     [Since 2.9] Set if the current face (or named instance) has been
+   *     altered with @FT_Set_MM_Design_Coordinates,
+   *     @FT_Set_Var_Design_Coordinates, @FT_Set_Var_Blend_Coordinates, or
+   *     @FT_Set_MM_WeightVector to select a non-default instance.
+   *
+   *   FT_FACE_FLAG_SVG ::
+   *     [Since 2.12] The face has an 'SVG~' OpenType table.
+   *
+   *   FT_FACE_FLAG_SBIX ::
+   *     [Since 2.12] The face has an 'sbix' OpenType table *and* outlines.
+   *     For such fonts, @FT_FACE_FLAG_SCALABLE is not set by default to
+   *     retain backward compatibility.
+   *
+   *   FT_FACE_FLAG_SBIX_OVERLAY ::
+   *     [Since 2.12] The face has an 'sbix' OpenType table where outlines
+   *     should be drawn on top of bitmap strikes.

+   *   handling so that the face is treated as an ordinary outline font with

+   *   The size metrics structure gives the metrics of a size object.

+   * @fields:
+   *   x_ppem ::
+   *     The width of the scaled EM square in pixels, hence the term 'ppem'
+   *     (pixels per EM).  It is also referred to as 'nominal width'.
+   *
+   *   y_ppem ::
+   *     The height of the scaled EM square in pixels, hence the term 'ppem'
+   *     (pixels per EM).  It is also referred to as 'nominal height'.
+   *
+   *   x_scale ::
+   *     A 16.16 fractional scaling value to convert horizontal metrics from
+   *     font units to 26.6 fractional pixels.  Only relevant for scalable
+   *     font formats.
+   *
+   *   y_scale ::
+   *     A 16.16 fractional scaling value to convert vertical metrics from
+   *     font units to 26.6 fractional pixels.  Only relevant for scalable
+   *     font formats.
+   *
+   *   ascender ::
+   *     The ascender in 26.6 fractional pixels, rounded up to an integer
+   *     value.  See @FT_FaceRec for the details.
+   *
+   *   descender ::
+   *     The descender in 26.6 fractional pixels, rounded down to an integer
+   *     value.  See @FT_FaceRec for the details.
+   *
+   *   height ::
+   *     The height in 26.6 fractional pixels, rounded to an integer value.
+   *     See @FT_FaceRec for the details.
+   *
+   *   max_advance ::
+   *     The maximum advance width in 26.6 fractional pixels, rounded to an
+   *     integer value.  See @FT_FaceRec for the details.
+   *
+   * @note:
+   *   The scaling values, if relevant, are determined first during a size
+   *   changing operation.  The remaining fields are then set by the driver.
+   *   For scalable formats, they are usually set to scaled values of the
+   *   corresponding fields in @FT_FaceRec.  Some values like ascender or
+   *   descender are rounded for historical reasons; more precise values (for

+   *                                  size_metrics->y_scale );
+   *   ```
+   *
+   *   Note that due to glyph hinting and the selected rendering mode these
+   *   values are usually not exact; consequently, they must be treated as
+   *   unreliable with an error margin of at least one pixel!
+   *
+   *   Indeed, the only way to get the exact metrics is to render _all_
+   *   glyphs.  As this would be a definite performance hit, it is up to
+   *   client applications to perform such computations.
+   *
+   *   The `FT_Size_Metrics` structure is valid for bitmap fonts also.
+   *
+   *
+   *   **TrueType fonts with native bytecode hinting**
+   *
+   *   All applications that handle TrueType fonts with native hinting must
+   *   be aware that TTFs expect different rounding of vertical font
+   *   dimensions.  The application has to cater for this, especially if it

+   * @struct:
+   *   FT_GlyphSlotRec
+   *
+   * @description:
+   *   FreeType root glyph slot class structure.  A glyph slot is a container
+   *   where individual glyphs can be loaded, be they in outline or bitmap
+   *   format.
+   *
+   * @fields:
+   *   library ::
+   *     A handle to the FreeType library instance this slot belongs to.
+   *
+   *   face ::
+   *     A handle to the parent face object.
+   *
+   *   next ::
+   *     In some cases (like some font tools), several glyph slots per face
+   *     object can be a good thing.  As this is rare, the glyph slots are
+   *     listed through a direct, single-linked list using its `next` field.
+   *
+   *   glyph_index ::
+   *     [Since 2.10] The glyph index passed as an argument to @FT_Load_Glyph
+   *     while initializing the glyph slot.
+   *
+   *   generic ::
+   *     A typeless pointer unused by the FreeType library or any of its
+   *     drivers.  It can be used by client applications to link their own
+   *     data to each glyph slot object.
+   *
+   *   metrics ::
+   *     The metrics of the last loaded glyph in the slot.  The returned
+   *     values depend on the last load flags (see the @FT_Load_Glyph API
+   *     function) and can be expressed either in 26.6 fractional pixels or
+   *     font units.
+   *
+   *     Note that even when the glyph image is transformed, the metrics are
+   *     not.
+   *
+   *   linearHoriAdvance ::
+   *     The advance width of the unhinted glyph.  Its value is expressed in
+   *     16.16 fractional pixels, unless @FT_LOAD_LINEAR_DESIGN is set when
+   *     loading the glyph.  This field can be important to perform correct
+   *     WYSIWYG layout.  Only relevant for scalable glyphs.
+   *
+   *   linearVertAdvance ::
+   *     The advance height of the unhinted glyph.  Its value is expressed in
+   *     16.16 fractional pixels, unless @FT_LOAD_LINEAR_DESIGN is set when
+   *     loading the glyph.  This field can be important to perform correct
+   *     WYSIWYG layout.  Only relevant for scalable glyphs.
+   *
+   *   advance ::
+   *     This shorthand is, depending on @FT_LOAD_IGNORE_TRANSFORM, the
+   *     transformed (hinted) advance width for the glyph, in 26.6 fractional
+   *     pixel format.  As specified with @FT_LOAD_VERTICAL_LAYOUT, it uses
+   *     either the `horiAdvance` or the `vertAdvance` value of `metrics`
+   *     field.
+   *
+   *   format ::
+   *     This field indicates the format of the image contained in the glyph
+   *     slot.  Typically @FT_GLYPH_FORMAT_BITMAP, @FT_GLYPH_FORMAT_OUTLINE,
+   *     or @FT_GLYPH_FORMAT_COMPOSITE, but other values are possible.
+   *
+   *   bitmap ::
+   *     This field is used as a bitmap descriptor.  Note that the address
+   *     and content of the bitmap buffer can change between calls of
+   *     @FT_Load_Glyph and a few other functions.
+   *
+   *   bitmap_left ::
+   *     The bitmap's left bearing expressed in integer pixels.
+   *
+   *   bitmap_top ::
+   *     The bitmap's top bearing expressed in integer pixels.  This is the
+   *     distance from the baseline to the top-most glyph scanline, upwards
+   *     y~coordinates being **positive**.
+   *
+   *   outline ::
+   *     The outline descriptor for the current glyph image if its format is
+   *     @FT_GLYPH_FORMAT_OUTLINE.  Once a glyph is loaded, `outline` can be
+   *     transformed, distorted, emboldened, etc.  However, it must not be
+   *     freed.
+   *
+   *     [Since 2.10.1] If @FT_LOAD_NO_SCALE is set, outline coordinates of
+   *     OpenType variation fonts for a selected instance are internally
+   *     handled as 26.6 fractional font units but returned as (rounded)
+   *     integers, as expected.  To get unrounded font units, don't use
+   *     @FT_LOAD_NO_SCALE but load the glyph with @FT_LOAD_NO_HINTING and
+   *     scale it, using the font's `units_per_EM` value as the ppem.
+   *
+   *   num_subglyphs ::
+   *     The number of subglyphs in a composite glyph.  This field is only
+   *     valid for the composite glyph format that should normally only be
+   *     loaded with the @FT_LOAD_NO_RECURSE flag.
+   *
+   *   subglyphs ::
+   *     An array of subglyph descriptors for composite glyphs.  There are
+   *     `num_subglyphs` elements in there.  Currently internal to FreeType.
+   *
+   *   control_data ::
+   *     Certain font drivers can also return the control data for a given
+   *     glyph image (e.g.  TrueType bytecode, Type~1 charstrings, etc.).
+   *     This field is a pointer to such data; it is currently internal to
+   *     FreeType.
+   *
+   *   control_len ::
+   *     This is the length in bytes of the control data.  Currently internal
+   *     to FreeType.
+   *
+   *   other ::
+   *     Reserved.
+   *
+   *   lsb_delta ::
+   *     The difference between hinted and unhinted left side bearing while
+   *     auto-hinting is active.  Zero otherwise.
+   *
+   *   rsb_delta ::
+   *     The difference between hinted and unhinted right side bearing while
+   *     auto-hinting is active.  Zero otherwise.
+   *
+   * @note:
+   *   If @FT_Load_Glyph is called with default flags (see @FT_LOAD_DEFAULT)
+   *   the glyph image is loaded in the glyph slot in its native format
+   *   (e.g., an outline glyph for TrueType and Type~1 formats).  [Since 2.9]
+   *   The prospective bitmap metrics are calculated according to
+   *   @FT_LOAD_TARGET_XXX and other flags even for the outline glyph, even
+   *   if @FT_LOAD_RENDER is not set.
+   *
+   *   This image can later be converted into a bitmap by calling
+   *   @FT_Render_Glyph.  This function searches the current renderer for the
+   *   native image's format, then invokes it.
+   *
+   *   The renderer is in charge of transforming the native image through the
+   *   slot's face transformation fields, then converting it into a bitmap
+   *   that is returned in `slot->bitmap`.
+   *
+   *   Note that `slot->bitmap_left` and `slot->bitmap_top` are also used to
+   *   specify the position of the bitmap relative to the current pen
+   *   position (e.g., coordinates (0,0) on the baseline).  Of course,
+   *   `slot->format` is also changed to @FT_GLYPH_FORMAT_BITMAP.
+   *
+   *   Here is a small pseudo code fragment that shows how to use `lsb_delta`
+   *   and `rsb_delta` to do fractional positioning of glyphs:
+   *
+   *   ```
+   *     FT_GlyphSlot  slot     = face->glyph;
+   *     FT_Pos        origin_x = 0;
+   *
+   *
+   *     for all glyphs do
+   *       <load glyph with `FT_Load_Glyph'>
+   *
+   *       FT_Outline_Translate( slot->outline, origin_x & 63, 0 );

+   *       <save glyph image, or render glyph, or ...>
+   *
+   *       <compute kern between current and next glyph
+   *        and add it to `origin_x'>
+   *
+   *       origin_x += slot->advance.x;
+   *       origin_x += slot->lsb_delta - slot->rsb_delta;
+   *     endfor
+   *   ```
+   *
+   *   Here is another small pseudo code fragment that shows how to use
+   *   `lsb_delta` and `rsb_delta` to improve integer positioning of glyphs:
+   *
+   *   ```
+   *     FT_GlyphSlot  slot           = face->glyph;
+   *     FT_Pos        origin_x       = 0;
+   *     FT_Pos        prev_rsb_delta = 0;
+   *
+   *
+   *     for all glyphs do
+   *       <compute kern between current and previous glyph
+   *        and add it to `origin_x'>
+   *
+   *       <load glyph with `FT_Load_Glyph'>
+   *
+   *       if ( prev_rsb_delta - slot->lsb_delta >  32 )
+   *         origin_x -= 64;
+   *       else if ( prev_rsb_delta - slot->lsb_delta < -31 )
+   *         origin_x += 64;
+   *
+   *       prev_rsb_delta = slot->rsb_delta;
+   *
+   *       <save glyph image, or render glyph, or ...>
+   *
+   *       origin_x += slot->advance.x;
+   *     endfor
+   *   ```
+   *
+   *   If you use strong auto-hinting, you **must** apply these delta values!
+   *   Otherwise you will experience far too large inter-glyph spacing at
+   *   small rendering sizes in most cases.  Note that it doesn't harm to use
+   *   the above code for other hinting modes also, since the delta values
+   *   are zero then.

+   * @struct:
+   *   FT_Open_Args
+   *
+   * @description:
+   *   A structure to indicate how to open a new font file or stream.  A
+   *   pointer to such a structure can be used as a parameter for the
+   *   functions @FT_Open_Face and @FT_Attach_Stream.
+   *
+   * @fields:
+   *   flags ::
+   *     A set of bit flags indicating how to use the structure.
+   *
+   *   memory_base ::
+   *     The first byte of the file in memory.
+   *
+   *   memory_size ::
+   *     The size in bytes of the file in memory.
+   *
+   *   pathname ::
+   *     A pointer to an 8-bit file pathname, which must be a C~string (i.e.,
+   *     no null bytes except at the very end).  The pointer is not owned by
+   *     FreeType.
+   *
+   *   stream ::
+   *     A handle to a source stream object.
+   *
+   *   driver ::
+   *     This field is exclusively used by @FT_Open_Face; it simply specifies
+   *     the font driver to use for opening the face.  If set to `NULL`,
+   *     FreeType tries to load the face with each one of the drivers in its
+   *     list.
+   *
+   *   num_params ::
+   *     The number of extra parameters.
+   *
+   *   params ::
+   *     Extra parameters passed to the font driver when opening a new face.
+   *
+   * @note:
+   *   The stream type is determined by the contents of `flags`:
+   *
+   *   If the @FT_OPEN_MEMORY bit is set, assume that this is a memory file
+   *   of `memory_size` bytes, located at `memory_address`.  The data are not
+   *   copied, and the client is responsible for releasing and destroying
+   *   them _after_ the corresponding call to @FT_Done_Face.
+   *
+   *   Otherwise, if the @FT_OPEN_STREAM bit is set, assume that a custom
+   *   input stream `stream` is used.
+   *
+   *   Otherwise, if the @FT_OPEN_PATHNAME bit is set, assume that this is a
+   *   normal file and use `pathname` to open it.
+   *
+   *   If none of the above bits are set or if multiple are set at the same
+   *   time, the flags are invalid and @FT_Open_Face fails.
+   *
+   *   If the @FT_OPEN_DRIVER bit is set, @FT_Open_Face only tries to open
+   *   the file with the driver whose handler is in `driver`.
+   *
+   *   If the @FT_OPEN_PARAMS bit is set, the parameters given by
+   *   `num_params` and `params` is used.  They are ignored otherwise.
+   *
+   *   Ideally, both the `pathname` and `params` fields should be tagged as
+   *   'const'; this is missing for API backward compatibility.  In other
+   *   words, applications should treat them as read-only.

+   *     A handle to the library resource.
+   *

+   *   args ::

+   *     caller.
+   *
+   *   face_index ::
+   *     This field holds two different values.  Bits 0-15 are the index of
+   *     the face in the font file (starting with value~0).  Set it to~0 if
+   *     there is only one face in the font file.
+   *
+   *     [Since 2.6.1] Bits 16-30 are relevant to GX and OpenType variation
+   *     fonts only, specifying the named instance index for the current face
+   *     index (starting with value~1; value~0 makes FreeType ignore named
+   *     instances).  For non-variation fonts, bits 16-30 are ignored.
+   *     Assuming that you want to access the third named instance in face~4,
+   *     `face_index` should be set to 0x00030004.  If you want to access
+   *     face~4 without variation handling, simply set `face_index` to
+   *     value~4.
+   *
+   *     `FT_Open_Face` and its siblings can be used to quickly check whether
+   *     the font format of a given font resource is supported by FreeType.
+   *     In general, if the `face_index` argument is negative, the function's
+   *     return value is~0 if the font format is recognized, or non-zero
+   *     otherwise.  The function allocates a more or less empty face handle
+   *     in `*aface` (if `aface` isn't `NULL`); the only two useful fields in
+   *     this special case are `face->num_faces` and `face->style_flags`.
+   *     For any negative value of `face_index`, `face->num_faces` gives the
+   *     number of faces within the font file.  For the negative value
+   *     '-(N+1)' (with 'N' a non-negative 16-bit value), bits 16-30 in
+   *     `face->style_flags` give the number of named instances in face 'N'
+   *     if we have a variation font (or zero otherwise).  After examination,
+   *     the returned @FT_Face structure should be deallocated with a call to
+   *     @FT_Done_Face.
+   *
+   * @output:
+   *   aface ::
+   *     A handle to a new face object.  If `face_index` is greater than or
+   *     equal to zero, it must be non-`NULL`.
+   *
+   * @return:
+   *   FreeType error code.  0~means success.
+   *
+   * @note:
+   *   Unlike FreeType 1.x, this function automatically creates a glyph slot
+   *   for the face object that can be accessed directly through
+   *   `face->glyph`.
+   *
+   *   Each new face object created with this function also owns a default
+   *   @FT_Size object, accessible as `face->size`.
+   *
+   *   One @FT_Library instance can have multiple face objects, that is,
+   *   @FT_Open_Face and its siblings can be called multiple times using the
+   *   same `library` argument.
+   *
+   *   See the discussion of reference counters in the description of
+   *   @FT_Reference_Face.
+   *
+   *   If `FT_OPEN_STREAM` is set in `args->flags`, the stream in
+   *   `args->stream` is automatically closed before this function returns
+   *   any error (including `FT_Err_Invalid_Argument`).
+   *
+   * @example:
+   *   To loop over all faces, use code similar to the following snippet
+   *   (omitting the error handling).
+   *
+   *   ```
+   *     ...
+   *     FT_Face  face;
+   *     FT_Long  i, num_faces;
+   *
+   *
+   *     error = FT_Open_Face( library, args, -1, &face );
+   *     if ( error ) { ... }
+   *
+   *     num_faces = face->num_faces;
+   *     FT_Done_Face( face );
+   *
+   *     for ( i = 0; i < num_faces; i++ )
+   *     {
+   *       ...
+   *       error = FT_Open_Face( library, args, i, &face );
+   *       ...
+   *       FT_Done_Face( face );
+   *       ...
+   *     }
+   *   ```
+   *
+   *   To loop over all valid values for `face_index`, use something similar
+   *   to the following snippet, again without error handling.  The code
+   *   accesses all faces immediately (thus only a single call of
+   *   `FT_Open_Face` within the do-loop), with and without named instances.
+   *
+   *   ```
+   *     ...
+   *     FT_Face  face;
+   *
+   *     FT_Long  num_faces     = 0;
+   *     FT_Long  num_instances = 0;
+   *
+   *     FT_Long  face_idx     = 0;
+   *     FT_Long  instance_idx = 0;
+   *
+   *
+   *     do
+   *     {
+   *       FT_Long  id = ( instance_idx << 16 ) + face_idx;
+   *
+   *
+   *       error = FT_Open_Face( library, args, id, &face );
+   *       if ( error ) { ... }
+   *
+   *       num_faces     = face->num_faces;
+   *       num_instances = face->style_flags >> 16;
+   *
+   *       ...
+   *
+   *       FT_Done_Face( face );
+   *
+   *       if ( instance_idx < num_instances )
+   *         instance_idx++;
+   *       else
+   *       {
+   *         face_idx++;
+   *         instance_idx = 0;
+   *       }
+   *
+   *     } while ( face_idx < num_faces )

+   * @enum:
+   *   FT_Render_Mode
+   *
+   * @description:
+   *   Render modes supported by FreeType~2.  Each mode corresponds to a
+   *   specific type of scanline conversion performed on the outline.
+   *
+   *   For bitmap fonts and embedded bitmaps the `bitmap->pixel_mode` field
+   *   in the @FT_GlyphSlotRec structure gives the format of the returned
+   *   bitmap.
+   *
+   *   All modes except @FT_RENDER_MODE_MONO use 256 levels of opacity,
+   *   indicating pixel coverage.  Use linear alpha blending and gamma
+   *   correction to correctly render non-monochrome glyph bitmaps onto a
+   *   surface; see @FT_Render_Glyph.
+   *
+   *   The @FT_RENDER_MODE_SDF is a special render mode that uses up to 256
+   *   distance values, indicating the signed distance from the grid position
+   *   to the nearest outline.
+   *
+   * @values:
+   *   FT_RENDER_MODE_NORMAL ::
+   *     Default render mode; it corresponds to 8-bit anti-aliased bitmaps.
+   *
+   *   FT_RENDER_MODE_LIGHT ::
+   *     This is equivalent to @FT_RENDER_MODE_NORMAL.  It is only defined as
+   *     a separate value because render modes are also used indirectly to
+   *     define hinting algorithm selectors.  See @FT_LOAD_TARGET_XXX for
+   *     details.
+   *
+   *   FT_RENDER_MODE_MONO ::
+   *     This mode corresponds to 1-bit bitmaps (with 2~levels of opacity).
+   *
+   *   FT_RENDER_MODE_LCD ::
+   *     This mode corresponds to horizontal RGB and BGR subpixel displays
+   *     like LCD screens.  It produces 8-bit bitmaps that are 3~times the
+   *     width of the original glyph outline in pixels, and which use the
+   *     @FT_PIXEL_MODE_LCD mode.
+   *
+   *   FT_RENDER_MODE_LCD_V ::
+   *     This mode corresponds to vertical RGB and BGR subpixel displays
+   *     (like PDA screens, rotated LCD displays, etc.).  It produces 8-bit
+   *     bitmaps that are 3~times the height of the original glyph outline in
+   *     pixels and use the @FT_PIXEL_MODE_LCD_V mode.
+   *
+   *   FT_RENDER_MODE_SDF ::
+   *     This mode corresponds to 8-bit, single-channel signed distance field
+   *     (SDF) bitmaps.  Each pixel in the SDF grid is the value from the
+   *     pixel's position to the nearest glyph's outline.  The distances are
+   *     calculated from the center of the pixel and are positive if they are
+   *     filled by the outline (i.e., inside the outline) and negative
+   *     otherwise.  Check the note below on how to convert the output values
+   *     to usable data.
+   *
+   * @note:
+   *   The selected render mode only affects vector glyphs of a font.
+   *   Embedded bitmaps often have a different pixel mode like
+   *   @FT_PIXEL_MODE_MONO.  You can use @FT_Bitmap_Convert to transform them
+   *   into 8-bit pixmaps.
+   *
+   *   For @FT_RENDER_MODE_SDF the output bitmap buffer contains normalized
+   *   distances that are packed into unsigned 8-bit values.  To get pixel
+   *   values in floating point representation use the following pseudo-C
+   *   code for the conversion.
+   *
+   *   ```
+   *   // Load glyph and render using FT_RENDER_MODE_SDF,
+   *   // then use the output buffer as follows.
+   *
+   *   ...
+   *   FT_Byte  buffer = glyph->bitmap->buffer;
+   *
+   *
+   *   for pixel in buffer
+   *   {
+   *     // `sd` is the signed distance and `spread` is the current spread;
+   *     // the default spread is 2 and can be changed.
+   *
+   *     float  sd = (float)pixel - 128.0f;
+   *
+   *
+   *     // Convert to pixel values.
+   *     sd = ( sd / 128.0f ) * spread;
+   *
+   *     // Store `sd` in a buffer or use as required.
+   *   }
+   *
+   *   ```
+   *
+   *   FreeType has two rasterizers for generating SDF, namely:
+   *
+   *   1. `sdf` for generating SDF directly from glyph's outline, and
+   *
+   *   2. `bsdf` for generating SDF from rasterized bitmaps.
+   *
+   *   Depending on the glyph type (i.e., outline or bitmap), one of the two
+   *   rasterizers is chosen at runtime and used for generating SDFs.  To
+   *   force the use of `bsdf` you should render the glyph with any of the
+   *   FreeType's other rendering modes (e.g., `FT_RENDER_MODE_NORMAL`) and
+   *   then re-render with `FT_RENDER_MODE_SDF`.
+   *
+   *   There are some issues with stability and possible failures of the SDF
+   *   renderers (specifically `sdf`).
+   *
+   *   1. The `sdf` rasterizer is sensitive to really small features (e.g.,
+   *      sharp turns that are less than 1~pixel) and imperfections in the
+   *      glyph's outline, causing artifacts in the final output.
+   *
+   *   2. The `sdf` rasterizer has limited support for handling intersecting
+   *      contours and *cannot* handle self-intersecting contours whatsoever.
+   *      Self-intersection happens when a single connected contour
+   *      intersects itself at some point; having these in your font
+   *      definitely poses a problem to the rasterizer and cause artifacts,
+   *      too.
+   *
+   *   3. Generating SDF for really small glyphs may result in undesirable
+   *      output; the pixel grid (which stores distance information) becomes
+   *      too coarse.
+   *
+   *   4. Since the output buffer is normalized, precision at smaller spreads
+   *      is greater than precision at larger spread values because the
+   *      output range of [0..255] gets mapped to a smaller SDF range.  A
+   *      spread of~2 should be sufficient in most cases.
+   *
+   *   Points (1) and (2) can be avoided by using the `bsdf` rasterizer,
+   *   which is more stable than the `sdf` rasterizer in general.

+   *   FT_Render_Glyph
+   *
+   * @description:
+   *   Convert a given glyph image to a bitmap.  It does so by inspecting the
+   *   glyph image format, finding the relevant renderer, and invoking it.
+   *
+   * @inout:
+   *   slot ::
+   *     A handle to the glyph slot containing the image to convert.
+   *
+   * @input:
+   *   render_mode ::
+   *     The render mode used to render the glyph image into a bitmap.  See
+   *     @FT_Render_Mode for a list of possible values.
+   *
+   *     If @FT_RENDER_MODE_NORMAL is used, a previous call of @FT_Load_Glyph
+   *     with flag @FT_LOAD_COLOR makes `FT_Render_Glyph` provide a default
+   *     blending of colored glyph layers associated with the current glyph
+   *     slot (provided the font contains such layers) instead of rendering
+   *     the glyph slot's outline.  This is an experimental feature; see
+   *     @FT_LOAD_COLOR for more information.
+   *
+   * @return:
+   *   FreeType error code.  0~means success.
+   *
+   * @note:
+   *   When FreeType outputs a bitmap of a glyph, it really outputs an alpha
+   *   coverage map.  If a pixel is completely covered by a filled-in
+   *   outline, the bitmap contains 0xFF at that pixel, meaning that
+   *   0xFF/0xFF fraction of that pixel is covered, meaning the pixel is 100%
+   *   black (or 0% bright).  If a pixel is only 50% covered (value 0x80),
+   *   the pixel is made 50% black (50% bright or a middle shade of grey).
+   *   0% covered means 0% black (100% bright or white).
+   *
+   *   On high-DPI screens like on smartphones and tablets, the pixels are so
+   *   small that their chance of being completely covered and therefore
+   *   completely black are fairly good.  On the low-DPI screens, however,
+   *   the situation is different.  The pixels are too large for most of the
+   *   details of a glyph and shades of gray are the norm rather than the
+   *   exception.
+   *
+   *   This is relevant because all our screens have a second problem: they
+   *   are not linear.  1~+~1 is not~2.  Twice the value does not result in
+   *   twice the brightness.  When a pixel is only 50% covered, the coverage
+   *   map says 50% black, and this translates to a pixel value of 128 when
+   *   you use 8~bits per channel (0-255).  However, this does not translate
+   *   to 50% brightness for that pixel on our sRGB and gamma~2.2 screens.
+   *   Due to their non-linearity, they dwell longer in the darks and only a
+   *   pixel value of about 186 results in 50% brightness -- 128 ends up too
+   *   dark on both bright and dark backgrounds.  The net result is that dark
+   *   text looks burnt-out, pixely and blotchy on bright background, bright
+   *   text too frail on dark backgrounds, and colored text on colored
+   *   background (for example, red on green) seems to have dark halos or
+   *   'dirt' around it.  The situation is especially ugly for diagonal stems
+   *   like in 'w' glyph shapes where the quality of FreeType's anti-aliasing
+   *   depends on the correct display of grays.  On high-DPI screens where
+   *   smaller, fully black pixels reign supreme, this doesn't matter, but on
+   *   our low-DPI screens with all the gray shades, it does.  0% and 100%
+   *   brightness are the same things in linear and non-linear space, just
+   *   all the shades in-between aren't.
+   *
+   *   The blending function for placing text over a background is
+   *
+   *   ```
+   *     dst = alpha * src + (1 - alpha) * dst    ,
+   *   ```
+   *
+   *   which is known as the OVER operator.
+   *
+   *   To correctly composite an anti-aliased pixel of a glyph onto a
+   *   surface,
+   *
+   *   1. take the foreground and background colors (e.g., in sRGB space)
+   *      and apply gamma to get them in a linear space,
+   *
+   *   2. use OVER to blend the two linear colors using the glyph pixel
+   *      as the alpha value (remember, the glyph bitmap is an alpha coverage
+   *      bitmap), and
+   *
+   *   3. apply inverse gamma to the blended pixel and write it back to
+   *      the image.
+   *
+   *   Internal testing at Adobe found that a target inverse gamma of~1.8 for
+   *   step~3 gives good results across a wide range of displays with an sRGB
+   *   gamma curve or a similar one.
+   *
+   *   This process can cost performance.  There is an approximation that
+   *   does not need to know about the background color; see
+   *   https://bel.fi/alankila/lcd/ and
+   *   https://bel.fi/alankila/lcd/alpcor.html for details.
+   *
+   *   **ATTENTION**: Linear blending is even more important when dealing

+   *   Three Mongolian Variation Selectors have the values U+180B-U+180D; 256
+   *   generic Variation Selectors are encoded in the ranges U+FE00-U+FE0F
+   *   and U+E0100-U+E01EF.  IVS currently use Variation Selectors from the
+   *   range U+E0100-U+E01EF only.
+   *
+   *   A VS consists of the base character value followed by a single
+   *   Variation Selector.  For example, to get the first variation of
+   *   U+9089, you have to write the character sequence `U+9089 U+E0100`.
+   *
+   *   Adobe and MS decided to support both standardized and ideographic VS
+   *   with a new cmap subtable (format~14).  It is an odd subtable because
+   *   it is not a mapping of input code points to glyphs, but contains lists
+   *   of all variations supported by the font.
+   *
+   *   A variation may be either 'default' or 'non-default' for a given font.
+   *   A default variation is the one you will get for that code point if you
+   *   look it up in the standard Unicode cmap.  A non-default variation is a
+   *   different glyph.

-   *
-   * @description:
-   *   *Experimental* *only*
-   *
-   *   The auto-hinter provides various script modules to hint glyphs.
-   *   Examples of supported scripts are Latin or CJK.  Before a glyph is
-   *   auto-hinted, the Unicode character map of the font gets examined, and
-   *   the script is then determined based on Unicode character ranges, see
-   *   below.
-   *
-   *   OpenType fonts, however, often provide much more glyphs than
-   *   character codes (small caps, superscripts, ligatures, swashes, etc.),
-   *   to be controlled by so-called `features'.  Handling OpenType features
-   *   can be quite complicated and thus needs a separate library on top of
-   *   FreeType.
-   *
-   *   The mapping between glyph indices and scripts (in the auto-hinter
-   *   sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
-   *   array with `num_glyphs' elements, as found in the font's @FT_Face
-   *   structure.  The `glyph-to-script-map' property returns a pointer to
-   *   this array, which can be modified as needed.  Note that the
-   *   modification should happen before the first glyph gets processed by
-   *   the auto-hinter so that the global analysis of the font shapes
-   *   actually uses the modified mapping.
-   *
-   *   The following example code demonstrates how to access it (omitting
-   *   the error handling).
-   *
-   *   {
-   *     FT_Library                library;
-   *     FT_Face                   face;
-   *     FT_Prop_GlyphToScriptMap  prop;
-   *

-   *     FT_Init_FreeType( &library );
-   *     FT_New_Face( library, "foo.ttf", 0, &face );
-   *
-   *     prop.face = face;
-   *
-   *     FT_Property_Get( library, "autofitter",
-   *                               "glyph-to-script-map", &prop );
-   *
-   *     // adjust `prop.map' as needed right here

-   *   switches warping on and off.
-   *
-   *   Warping only works in `light' auto-hinting mode.  The idea of the
-   *   code is to slightly scale and shift a glyph along the non-hinted
-   *   dimension (which is usually the horizontal axis) so that as much of
-   *   its segments are aligned (more or less) to the grid.  To find out a
-   *   glyph's optimal scaling and shifting value, various parameter
-   *   combinations are tried and scored.
-   *
-   *   By default, warping is off.  The example below shows how to switch on

-   *
-   * @note:
-   *   This property can be used with @FT_Property_Get also.
-   *
-   *   The warping code can also change advance widths.  Have a look at the
-   *   `lsb_delta' and `rsb_delta' fields in the @FT_GlyphSlotRec structure
-   *   for details on improving inter-glyph distances while rendering.
-   *
-   *   Since warping is a global property of the auto-hinter it is best to

+   *
+   *   A 'property' is a either key-value pair within the STARTPROPERTIES
+   *   ... ENDPROPERTIES block of a BDF font or a key-value pair from the
+   *   `info->props` array within a `FontRec` structure of a PCF font.
+   *
+   *   Integer properties are always stored as 'signed' within PCF fonts;
+   *   consequently, @BDF_PROPERTY_TYPE_CARDINAL is a possible return value
+   *   for BDF fonts only.
+   *
+   *   In case of error, `aproperty->type` is always set to

-   * <Description>
+   * @description:
    *   This section describes the FreeType~2 cache sub-system, which is used
    *   to limit the number of concurrently opened @FT_Face and @FT_Size
    *   objects, as well as caching information like character maps and glyph
    *   images while limiting their maximum memory usage.
    *
-   *   Note that all types and functions begin with the `FTC_' prefix.
+   *   Note that all types and functions begin with the `FTC_` prefix rather
+   *   than the usual `FT_` prefix in the rest of FreeType.
    *
-   *   The cache is highly portable and thus doesn't know anything about the
-   *   fonts installed on your system, or how to access them.  This implies
-   *   the following scheme:
+   *   The cache is highly portable and, thus, doesn't know anything about
+   *   the fonts installed on your system, or how to access them.  Therefore,
+   *   it requires the following.
    *
-   *   First, available or installed font faces are uniquely identified by
-   *   @FTC_FaceID values, provided to the cache by the client.  Note that
-   *   the cache only stores and compares these values, and doesn't try to
-   *   interpret them in any way.
+   *   * @FTC_FaceID, an arbitrary non-zero value that uniquely identifies
+   *     available or installed font faces, has to be provided to the
+   *     cache by the client.  Note that the cache only stores and compares
+   *     these values and doesn't try to interpret them in any way, but they
+   *     have to be persistent on the client side.
    *
-   *   Second, the cache calls, only when needed, a client-provided function
-   *   to convert an @FTC_FaceID into a new @FT_Face object.  The latter is
-   *   then completely managed by the cache, including its termination
-   *   through @FT_Done_Face.  To monitor termination of face objects, the
-   *   finalizer callback in the `generic' field of the @FT_Face object can
-   *   be used, which might also be used to store the @FTC_FaceID of the
-   *   face.
+   *   * @FTC_Face_Requester, a method to convert an @FTC_FaceID into a new
+   *     @FT_Face object when necessary, has to be provided to the cache by
+   *     the client.  The @FT_Face object is completely managed by the cache,
+   *     including its termination through @FT_Done_Face.  To monitor
+   *     termination of face objects, the finalizer callback in the `generic`
+   *     field of the @FT_Face object can be used, which might also be used
+   *     to store the @FTC_FaceID of the face.
    *
-   *   Clients are free to map face IDs to anything else.  The most simple
-   *   usage is to associate them to a (pathname,face_index) pair that is
-   *   used to call @FT_New_Face.  However, more complex schemes are also
-   *   possible.
+   *   Clients are free to map face IDs to anything useful.  The most simple
+   *   usage is, for example, to associate them to a `{pathname,face_index}`
+   *   pair that is then used by @FTC_Face_Requester to call @FT_New_Face.
+   *   However, more complex schemes are also possible.
    *
    *   Note that for the cache to work correctly, the face ID values must be
-   *   *persistent*, which means that the contents they point to should not
+   *   **persistent**, which means that the contents they point to should not
    *   change at runtime, or that their value should not become invalid.
-   *
    *   If this is unavoidable (e.g., when a font is uninstalled at runtime),
-   *   you should call @FTC_Manager_RemoveFaceID as soon as possible, to let
-   *   the cache get rid of any references to the old @FTC_FaceID it may
-   *   keep internally.  Failure to do so will lead to incorrect behaviour
-   *   or even crashes.
+   *   you should call @FTC_Manager_RemoveFaceID as soon as possible to let
+   *   the cache get rid of any references to the old @FTC_FaceID it may keep
+   *   internally.  Failure to do so will lead to incorrect behaviour or even
+   *   crashes in @FTC_Face_Requester.
    *
    *   To use the cache, start with calling @FTC_Manager_New to create a new
    *   @FTC_Manager object, which models a single cache instance.  You can
    *   then look up @FT_Face and @FT_Size objects with
-   *   @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively.
-   *
-   *   If you want to use the charmap caching, call @FTC_CMapCache_New, then
-   *   later use @FTC_CMapCache_Lookup to perform the equivalent of
-   *   @FT_Get_Char_Index, only much faster.
+   *   @FTC_Manager_LookupFace and @FTC_Manager_LookupSize, respectively, and
+   *   use them in any FreeType work stream.  You can also cache other
+   *   FreeType objects as follows.
    *
-   *   If you want to use the @FT_Glyph caching, call @FTC_ImageCache, then
-   *   later use @FTC_ImageCache_Lookup to retrieve the corresponding
-   *   @FT_Glyph objects from the cache.
+   *   * If you want to use the charmap caching, call @FTC_CMapCache_New,
+   *     then later use @FTC_CMapCache_Lookup to perform the equivalent of
+   *     @FT_Get_Char_Index, only much faster.
    *
-   *   If you need lots of small bitmaps, it is much more memory efficient
-   *   to call @FTC_SBitCache_New followed by @FTC_SBitCache_Lookup.  This
-   *   returns @FTC_SBitRec structures, which are used to store small
-   *   bitmaps directly.  (A small bitmap is one whose metrics and
-   *   dimensions all fit into 8-bit integers).
+   *   * If you want to use the @FT_Glyph caching, call @FTC_ImageCache_New,
+   *     then later use @FTC_ImageCache_Lookup to retrieve the corresponding
+   *     @FT_Glyph objects from the cache.
    *
-   *   We hope to also provide a kerning cache in the near future.

-   * @title:
-   *   The CFF driver
-   *
-   * @abstract:
-   *   Controlling the CFF driver module.
-   *
-   * @description:
-   *   While FreeType's CFF driver doesn't expose API functions by itself,
-   *   it is possible to control its behaviour with @FT_Property_Set and
-   *   @FT_Property_Get.  The list below gives the available properties
-   *   together with the necessary macros and structures.
-   *
-   *   The CFF driver's module name is `cff'.
-   *
-   *   *Hinting* *and* *antialiasing* *principles* *of* *the* *new* *engine*
-   *
-   *   The rasterizer is positioning horizontal features (e.g., ascender
-   *   height & x-height, or crossbars) on the pixel grid and minimizing the
-   *   amount of antialiasing applied to them, while placing vertical
-   *   features (vertical stems) on the pixel grid without hinting, thus
-   *   representing the stem position and weight accurately.  Sometimes the
-   *   vertical stems may be only partially black.  In this context,
-   *   `antialiasing' means that stems are not positioned exactly on pixel
-   *   borders, causing a fuzzy appearance.
-   *
-   *   There are two principles behind this approach.
-   *
-   *   1) No hinting in the horizontal direction: Unlike `superhinted'
-   *   TrueType, which changes glyph widths to accommodate regular
-   *   inter-glyph spacing, Adobe's approach is `faithful to the design' in
-   *   representing both the glyph width and the inter-glyph spacing
-   *   designed for the font.  This makes the screen display as close as it
-   *   can be to the result one would get with infinite resolution, while
-   *   preserving what is considered the key characteristics of each glyph.
-   *   Note that the distances between unhinted and grid-fitted positions at
-   *   small sizes are comparable to kerning values and thus would be
-   *   noticeable (and distracting) while reading if hinting were applied.
-   *
-   *   One of the reasons to not hint horizontally is antialiasing for LCD
-   *   screens: The pixel geometry of modern displays supplies three
-   *   vertical sub-pixels as the eye moves horizontally across each visible
-   *   pixel.  On devices where we can be certain this characteristic is
-   *   present a rasterizer can take advantage of the sub-pixels to add
-   *   increments of weight.  In Western writing systems this turns out to
-   *   be the more critical direction anyway; the weights and spacing of
-   *   vertical stems (see above) are central to Armenian, Cyrillic, Greek,
-   *   and Latin type designs.  Even when the rasterizer uses greyscale
-   *   antialiasing instead of color (a necessary compromise when one
-   *   doesn't know the screen characteristics), the unhinted vertical
-   *   features preserve the design's weight and spacing much better than
-   *   aliased type would.
-   *
-   *   2) Aligment in the vertical direction: Weights and spacing along the
-   *   y~axis are less critical; what is much more important is the visual
-   *   alignment of related features (like cap-height and x-height).  The
-   *   sense of alignment for these is enhanced by the sharpness of grid-fit
-   *   edges, while the cruder vertical resolution (full pixels instead of
-   *   1/3 pixels) is less of a problem.
-   *
-   *   On the technical side, horizontal alignment zones for ascender,
-   *   x-height, and other important height values (traditionally called
-   *   `blue zones') as defined in the font are positioned independently,
-   *   each being rounded to the nearest pixel edge, taking care of
-   *   overshoot suppression at small sizes, stem darkening, and scaling.
-   *
-   *   Hstems (this is, hint values defined in the font to help align
-   *   horizontal features) that fall within a blue zone are said to be
-   *   `captured' and are aligned to that zone.  Uncaptured stems are moved
-   *   in one of four ways, top edge up or down, bottom edge up or down.
-   *   Unless there are conflicting hstems, the smallest movement is taken
-   *   to minimize distortion.

-   *
-   *   The x~values give the stem width, and the y~values the darkening
-   *   amount.  The unit is 1000th of pixels.  All coordinate values must be

+   *   The glyph layer data for a given glyph index, if present, provides an
+   *   alternative, multi-color glyph representation: Instead of rendering
+   *   the outline or bitmap with the given glyph index, glyphs with the
+   *   indices and colors returned by this function are rendered layer by
+   *   layer.
+   *
+   *   The returned elements are ordered in the z~direction from bottom to
+   *   top; the 'n'th element should be rendered with the associated palette
+   *   color and blended on top of the already rendered layers (elements 0,
+   *   1, ..., n-1).

+   * @input:
+   *   face ::
+   *     A handle to the parent face object.

+   *
+   * @inout:
+   *   iterator ::
+   *     An @FT_LayerIterator object.  For the first call you should set
+   *     `iterator->p` to `NULL`.  For all following calls, simply use the
+   *     same object again.
+   *
+   * @output:
+   *   aglyph_index ::
+   *     The glyph index of the current layer.
+   *
+   *   acolor_index ::
+   *     The color index into the font face's color palette of the current
+   *     layer.  The value 0xFFFF is special; it doesn't reference a palette
+   *     entry but indicates that the text foreground color should be used
+   *     instead (to be set up by the application outside of FreeType).
+   *
+   *     The color palette can be retrieved with @FT_Palette_Select.
+   *
+   * @return:

+   *   are no layers at all), value~0 gets returned.  In case of an error,

+   *
+   * @note:
+   *   This function is necessary if you want to handle glyph layers by
+   *   yourself.  In particular, functions that operate with @FT_GlyphRec
+   *   objects (like @FT_Get_Glyph or @FT_Glyph_To_Bitmap) don't have access
+   *   to this information.

-   *   If FreeType gets compiled with option AF_CONFIG_OPTION_USE_WARPER to
-   *   activate the warp hinting code in the auto-hinter, this property
-   *   switches warping on and off.
-   *
-   *   Warping only works in `normal' auto-hinting mode replacing it.
-   *   The idea of the code is to slightly scale and shift a glyph along
-   *   the non-hinted dimension (which is usually the horizontal axis) so
-   *   that as much of its segments are aligned (more or less) to the grid.
-   *   To find out a glyph's optimal scaling and shifting value, various
-   *   parameter combinations are tried and scored.
-   *
-   *   By default, warping is off.  The example below shows how to switch on

-   *   This property can be set via the `FREETYPE_PROPERTIES' environment

-   *   `lsb_delta' and `rsb_delta' fields in the @FT_GlyphSlotRec structure
-   *   for details on improving inter-glyph distances while rendering.
-   *
-   *   Since warping is a global property of the auto-hinter it is best to

+   *   Error Enumerations
+   *
+   * @abstract:
+   *   How to handle errors and error strings.
+   *
+   * @description:
+   *   The header file `fterrors.h` (which is automatically included by
+   *   `freetype.h`) defines the handling of FreeType's enumeration
+   *   constants.  It can also be used to generate error message strings
+   *   with a small macro trick explained below.
+   *
+   *   **Error Formats**
+   *
+   *   The configuration macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` can be
+   *   defined in `ftoption.h` in order to make the higher byte indicate the
+   *   module where the error has happened (this is not compatible with
+   *   standard builds of FreeType~2, however).  See the file `ftmoderr.h`
+   *   for more details.
+   *
+   *   **Error Message Strings**
+   *
+   *   Error definitions are set up with special macros that allow client
+   *   applications to build a table of error message strings.  The strings
+   *   are not included in a normal build of FreeType~2 to save space (most
+   *   client applications do not use them).
+   *
+   *   To do so, you have to define the following macros before including
+   *   this file.
+   *
+   *   ```
+   *     FT_ERROR_START_LIST
+   *   ```
+   *
+   *   This macro is called before anything else to define the start of the
+   *   error list.  It is followed by several `FT_ERROR_DEF` calls.
+   *
+   *   ```
+   *     FT_ERROR_DEF( e, v, s )
+   *   ```
+   *
+   *   This macro is called to define one single error.  'e' is the error
+   *   code identifier (e.g., `Invalid_Argument`), 'v' is the error's
+   *   numerical value, and 's' is the corresponding error string.
+   *
+   *   ```
+   *     FT_ERROR_END_LIST
+   *   ```
+   *
+   *   This macro ends the list.
+   *
+   *   Additionally, you have to undefine `FTERRORS_H_` before #including
+   *   this file.
+   *
+   *   Here is a simple example.
+   *
+   *   ```
+   *     #undef FTERRORS_H_
+   *     #define FT_ERRORDEF( e, v, s )  { e, s },
+   *     #define FT_ERROR_START_LIST     {
+   *     #define FT_ERROR_END_LIST       { 0, NULL } };
+   *
+   *     const struct
+   *     {
+   *       int          err_code;
+   *       const char*  err_msg;
+   *     } ft_errors[] =
+   *
+   *     #include <freetype/fterrors.h>
+   *   ```
+   *
+   *   An alternative to using an array is a switch statement.
+   *
+   *   ```
+   *     #undef FTERRORS_H_
+   *     #define FT_ERROR_START_LIST     switch ( error_code ) {
+   *     #define FT_ERRORDEF( e, v, s )    case v: return s;
+   *     #define FT_ERROR_END_LIST       }
+   *   ```
+   *
+   *   If you use `FT_CONFIG_OPTION_USE_MODULE_ERRORS`, `error_code` should
+   *   be replaced with `FT_ERROR_BASE(error_code)` in the last example.

+   *
+   *   FT_PIXEL_MODE_MONO ::
+   *     A monochrome bitmap, using 1~bit per pixel.  Note that pixels are
+   *     stored in most-significant order (MSB), which means that the
+   *     left-most pixel in a byte has value 128.
+   *
+   *   FT_PIXEL_MODE_GRAY ::
+   *     An 8-bit bitmap, generally used to represent anti-aliased glyph
+   *     images.  Each pixel is stored in one byte.  Note that the number of
+   *     'gray' levels is stored in the `num_grays` field of the @FT_Bitmap
+   *     structure (it generally is 256).
+   *
+   *   FT_PIXEL_MODE_GRAY2 ::
+   *     A 2-bit per pixel bitmap, used to represent embedded anti-aliased
+   *     bitmaps in font files according to the OpenType specification.  We
+   *     haven't found a single font using this format, however.
+   *
+   *   FT_PIXEL_MODE_GRAY4 ::
+   *     A 4-bit per pixel bitmap, representing embedded anti-aliased bitmaps
+   *     in font files according to the OpenType specification.  We haven't
+   *     found a single font using this format, however.
+   *
+   *   FT_PIXEL_MODE_LCD ::
+   *     An 8-bit bitmap, representing RGB or BGR decimated glyph images used
+   *     for display on LCD displays; the bitmap is three times wider than

+   *     representing a color image (such as emoticons) with alpha channel.
+   *     For each pixel, the format is BGRA, which means, the blue channel
+   *     comes first in memory.  The color channels are pre-multiplied and in

+   *   A structure used to describe a bitmap or pixmap to the raster.  Note
+   *   that we now manage pixmaps of various depths through the `pixel_mode`
+   *   field.
+   *
+   * @fields:
+   *   rows ::
+   *     The number of bitmap rows.
+   *
+   *   width ::
+   *     The number of pixels in bitmap row.
+   *
+   *   pitch ::
+   *     The pitch's absolute value is the number of bytes taken by one
+   *     bitmap row, including padding.  However, the pitch is positive when
+   *     the bitmap has a 'down' flow, and negative when it has an 'up' flow.
+   *     In all cases, the pitch is an offset to add to a bitmap pointer in
+   *     order to go down one row.
+   *
+   *     Note that 'padding' means the alignment of a bitmap to a byte
+   *     border, and FreeType functions normally align to the smallest
+   *     possible integer value.
+   *
+   *     For the B/W rasterizer, `pitch` is always an even number.
+   *
+   *     To change the pitch of a bitmap (say, to make it a multiple of 4),
+   *     use @FT_Bitmap_Convert.  Alternatively, you might use callback
+   *     functions to directly render to the application's surface; see the
+   *     file `example2.cpp` in the tutorial for a demonstration.
+   *
+   *   buffer ::
+   *     A typeless pointer to the bitmap buffer.  This value should be
+   *     aligned on 32-bit boundaries in most cases.
+   *
+   *   num_grays ::
+   *     This field is only used with @FT_PIXEL_MODE_GRAY; it gives the
+   *     number of gray levels used in the bitmap.
+   *
+   *   pixel_mode ::
+   *     The pixel mode, i.e., how pixel bits are stored.  See @FT_Pixel_Mode
+   *     for possible values.
+   *
+   *   palette_mode ::
+   *     This field is intended for paletted pixel modes; it indicates how
+   *     the palette is stored.  Not used currently.
+   *
+   *   palette ::
+   *     A typeless pointer to the bitmap palette; this field is intended for
+   *     paletted pixel modes.  Not used currently.
+   *
+   * @note:
+   *   `width` and `rows` refer to the *physical* size of the bitmap, not the
+   *   *logical* one.  For example, if @FT_Pixel_Mode is set to
+   *   `FT_PIXEL_MODE_LCD`, the logical width is a just a third of the
+   *   physical one.

+   *
+   * @values:
+   *   FT_OUTLINE_NONE ::
+   *     Value~0 is reserved.
+   *
+   *   FT_OUTLINE_OWNER ::
+   *     If set, this flag indicates that the outline's field arrays (i.e.,
+   *     `points`, `flags`, and `contours`) are 'owned' by the outline
+   *     object, and should thus be freed when it is destroyed.
+   *
+   *   FT_OUTLINE_EVEN_ODD_FILL ::
+   *     By default, outlines are filled using the non-zero winding rule.  If
+   *     set to 1, the outline will be filled using the even-odd fill rule
+   *     (only works with the smooth rasterizer).
+   *
+   *   FT_OUTLINE_REVERSE_FILL ::
+   *     By default, outside contours of an outline are oriented in
+   *     clock-wise direction, as defined in the TrueType specification.
+   *     This flag is set if the outline uses the opposite direction
+   *     (typically for Type~1 fonts).  This flag is ignored by the scan
+   *     converter.
+   *
+   *   FT_OUTLINE_IGNORE_DROPOUTS ::
+   *     By default, the scan converter will try to detect drop-outs in an
+   *     outline and correct the glyph bitmap to ensure consistent shape
+   *     continuity.  If set, this flag hints the scan-line converter to
+   *     ignore such cases.  See below for more information.
+   *
+   *   FT_OUTLINE_SMART_DROPOUTS ::
+   *     Select smart dropout control.  If unset, use simple dropout control.
+   *     Ignored if @FT_OUTLINE_IGNORE_DROPOUTS is set.  See below for more
+   *     information.
+   *
+   *   FT_OUTLINE_INCLUDE_STUBS ::
+   *     If set, turn pixels on for 'stubs', otherwise exclude them.  Ignored
+   *     if @FT_OUTLINE_IGNORE_DROPOUTS is set.  See below for more
+   *     information.
+   *
+   *   FT_OUTLINE_OVERLAP ::
+   *     [Since 2.10.3] This flag indicates that this outline contains
+   *     overlapping contours and the anti-aliased renderer should perform
+   *     oversampling to mitigate possible artifacts.  This flag should _not_
+   *     be set for well designed glyphs without overlaps because it quadruples
+   *     the rendering time.
+   *
+   *   FT_OUTLINE_HIGH_PRECISION ::
+   *     This flag indicates that the scan-line converter should try to
+   *     convert this outline to bitmaps with the highest possible quality.
+   *     It is typically set for small character sizes.  Note that this is
+   *     only a hint that might be completely ignored by a given
+   *     scan-converter.
+   *
+   *   FT_OUTLINE_SINGLE_PASS ::
+   *     This flag is set to force a given scan-converter to only use a
+   *     single pass over the outline to render a bitmap glyph image.
+   *     Normally, it is set for very large character sizes.  It is only a
+   *     hint that might be completely ignored by a given scan-converter.
+   *
+   * @note:
+   *   The flags @FT_OUTLINE_IGNORE_DROPOUTS, @FT_OUTLINE_SMART_DROPOUTS, and
+   *   @FT_OUTLINE_INCLUDE_STUBS are ignored by the smooth rasterizer.
+   *
+   *   There exists a second mechanism to pass the drop-out mode to the B/W
+   *   rasterizer; see the `tags` field in @FT_Outline.
+   *
+   *   Please refer to the description of the 'SCANTYPE' instruction in the
+   *   OpenType specification (in file `ttinst1.doc`) how simple drop-outs,
+   *   smart drop-outs, and stubs are defined.

+   * @abstract:
+   *   How vectorial outlines are converted into bitmaps and pixmaps.
+   *
+   * @description:
+   *   A raster or a rasterizer is a scan converter in charge of producing a
+   *   pixel coverage bitmap that can be used as an alpha channel when
+   *   compositing a glyph with a background.  FreeType comes with two
+   *   rasterizers: bilevel `raster1` and anti-aliased `smooth` are two
+   *   separate modules.  They are usually called from the high-level
+   *   @FT_Load_Glyph or @FT_Render_Glyph functions and produce the entire
+   *   coverage bitmap at once, while staying largely invisible to users.
+   *
+   *   Instead of working with complete coverage bitmaps, it is also possible
+   *   to intercept consecutive pixel runs on the same scanline with the same
+   *   coverage, called _spans_, and process them individually.  Only the
+   *   `smooth` rasterizer permits this when calling @FT_Outline_Render with
+   *   @FT_Raster_Params as described below.
+   *
+   *   Working with either complete bitmaps or spans it is important to think
+   *   of them as colorless coverage objects suitable as alpha channels to
+   *   blend arbitrary colors with a background.  For best results, it is
+   *   recommended to use gamma correction, too.
+   *
+   *   This section also describes the public API needed to set up alternative
+   *   @FT_Renderer modules.

-   *   LCD Filtering
+   *   Subpixel Rendering
    *
    * @abstract:
-   *   Reduce color fringes of subpixel-rendered bitmaps.
+   *   API to control subpixel rendering.
    *
    * @description:
-   *   Should you #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your
-   *   `ftoption.h', which enables patented ClearType-style rendering,
-   *   the LCD-optimized glyph bitmaps should be filtered to reduce color
-   *   fringes inherent to this technology.  The default FreeType LCD
-   *   rendering uses different technology, and API described below,
-   *   although available, does nothing.
+   *   FreeType provides two alternative subpixel rendering technologies.
+   *   Should you define `FT_CONFIG_OPTION_SUBPIXEL_RENDERING` in your
+   *   `ftoption.h` file, this enables ClearType-style rendering.
+   *   Otherwise, Harmony LCD rendering is enabled.  These technologies are
+   *   controlled differently and API described below, although always
+   *   available, performs its function when appropriate method is enabled
+   *   and does nothing otherwise.
    *
    *   ClearType-style LCD rendering exploits the color-striped structure of
    *   LCD pixels, increasing the available resolution in the direction of
-   *   the stripe (usually horizontal RGB) by a factor of~3.  Since these
-   *   subpixels are color pixels, using them unfiltered creates severe
-   *   color fringes.  Use the @FT_Library_SetLcdFilter API to specify a
-   *   low-pass filter, which is then applied to subpixel-rendered bitmaps
-   *   generated through @FT_Render_Glyph.  The filter sacrifices some of
-   *   the higher resolution to reduce color fringes, making the glyph image
-   *   slightly blurrier.  Positional improvements will remain.
-   *
-   *   A filter should have two properties:
-   *
-   *   1) It should be normalized, meaning the sum of the 5~components
-   *      should be 256 (0x100).  It is possible to go above or under this
-   *      target sum, however: going under means tossing out contrast, going
-   *      over means invoking clamping and thereby non-linearities that
-   *      increase contrast somewhat at the expense of greater distortion
-   *      and color-fringing.  Contrast is better enhanced through stem
-   *      darkening.
-   *
-   *   2) It should be color-balanced, meaning a filter `{~a, b, c, b, a~}'
-   *      where a~+ b~=~c.  It distributes the computed coverage for one
-   *      subpixel to all subpixels equally, sacrificing some won resolution
-   *      but drastically reducing color-fringing.  Positioning improvements
-   *      remain!  Note that color-fringing can only really be minimized
-   *      when using a color-balanced filter and alpha-blending the glyph
-   *      onto a surface in linear space; see @FT_Render_Glyph.
-   *
-   *   Regarding the form, a filter can be a `boxy' filter or a `beveled'
-   *   filter.  Boxy filters are sharper but are less forgiving of non-ideal
-   *   gamma curves of a screen (viewing angles!), beveled filters are
-   *   fuzzier but more tolerant.
-   *
-   *   Examples:
-   *
-   *   - [0x10 0x40 0x70 0x40 0x10] is beveled and neither balanced nor
-   *     normalized.
-   *
-   *   - [0x1A 0x33 0x4D 0x33 0x1A] is beveled and balanced but not
-   *     normalized.
-   *
-   *   - [0x19 0x33 0x66 0x4c 0x19] is beveled and normalized but not
-   *     balanced.
-   *
-   *   - [0x00 0x4c 0x66 0x4c 0x00] is boxily beveled and normalized but not
-   *     balanced.
-   *
-   *   - [0x00 0x55 0x56 0x55 0x00] is boxy, normalized, and almost
-   *     balanced.
-   *
-   *   - [0x08 0x4D 0x56 0x4D 0x08] is beveled, normalized and, almost
-   *     balanced.
-   *
-   *   The filter affects glyph bitmaps rendered through @FT_Render_Glyph,
-   *   @FT_Load_Glyph, and @FT_Load_Char.  It does _not_ affect the output
-   *   of @FT_Outline_Render and @FT_Outline_Get_Bitmap.
-   *
-   *   If this feature is activated, the dimensions of LCD glyph bitmaps are
-   *   either wider or taller than the dimensions of the corresponding
-   *   outline with regard to the pixel grid.  For example, for
-   *   @FT_RENDER_MODE_LCD, the filter adds 3~subpixels to the left, and
-   *   3~subpixels to the right.  The bitmap offset values are adjusted
-   *   accordingly, so clients shouldn't need to modify their layout and
-   *   glyph positioning code when enabling the filter.
-   *
-   *   It is important to understand that linear alpha blending and gamma
-   *   correction is critical for correctly rendering glyphs onto surfaces
-   *   without artifacts and even more critical when subpixel rendering is
-   *   involved.
-   *
-   *   Each of the 3~alpha values (subpixels) is independently used to blend
-   *   one color channel.  That is, red alpha blends the red channel of the
-   *   text color with the red channel of the background pixel.  The
-   *   distribution of density values by the color-balanced filter assumes
-   *   alpha blending is done in linear space; only then color artifacts
-   *   cancel out.
+   *   the stripe (usually horizontal RGB) by a factor of~3.  Using the
+   *   subpixel coverages unfiltered can create severe color fringes
+   *   especially when rendering thin features.  Indeed, to produce
+   *   black-on-white text, the nearby color subpixels must be dimmed
+   *   evenly.  Therefore, an equalizing 5-tap FIR filter should be applied
+   *   to subpixel coverages regardless of pixel boundaries and should have
+   *   these properties:
+   *
+   *   1. It should be symmetrical, like {~a, b, c, b, a~}, to avoid
+   *      any shifts in appearance.
+   *
+   *   2. It should be color-balanced, meaning a~+ b~=~c, to reduce color
+   *      fringes by distributing the computed coverage for one subpixel to
+   *      all subpixels equally.
+   *
+   *   3. It should be normalized, meaning 2a~+ 2b~+ c~=~1.0 to maintain
+   *      overall brightness.
+   *
+   *   Boxy 3-tap filter {0, 1/3, 1/3, 1/3, 0} is sharper but is less
+   *   forgiving of non-ideal gamma curves of a screen (and viewing angles),
+   *   beveled filters are fuzzier but more tolerant.
+   *
+   *   Use the @FT_Library_SetLcdFilter or @FT_Library_SetLcdFilterWeights
+   *   API to specify a low-pass filter, which is then applied to
+   *   subpixel-rendered bitmaps generated through @FT_Render_Glyph.
+   *
+   *   Harmony LCD rendering is suitable to panels with any regular subpixel
+   *   structure, not just monitors with 3 color striped subpixels, as long
+   *   as the color subpixels have fixed positions relative to the pixel
+   *   center.  In this case, each color channel can be rendered separately
+   *   after shifting the outline opposite to the subpixel shift so that the
+   *   coverage maps are aligned.  This method is immune to color fringes
+   *   because the shifts do not change integral coverage.
+   *
+   *   The subpixel geometry must be specified by xy-coordinates for each
+   *   subpixel. By convention they may come in the RGB order: {{-1/3, 0},
+   *   {0, 0}, {1/3, 0}} for standard RGB striped panel or {{-1/6, 1/4},
+   *   {-1/6, -1/4}, {1/3, 0}} for a certain PenTile panel.
+   *
+   *   Use the @FT_Library_SetLcdGeometry API to specify subpixel positions.
+   *   If one follows the RGB order convention, the same order applies to the
+   *   resulting @FT_PIXEL_MODE_LCD and @FT_PIXEL_MODE_LCD_V bitmaps.  Note,
+   *   however, that the coordinate frame for the latter must be rotated
+   *   clockwise.  Harmony with default LCD geometry is equivalent to
+   *   ClearType with light filter.
+   *
+   *   As a result of ClearType filtering or Harmony shifts, the resulting
+   *   dimensions of LCD bitmaps can be slightly wider or taller than the
+   *   dimensions the original outline with regard to the pixel grid.
+   *   For example, for @FT_RENDER_MODE_LCD, the filter adds 2~subpixels to
+   *   the left, and 2~subpixels to the right.  The bitmap offset values are
+   *   adjusted accordingly, so clients shouldn't need to modify their layout
+   *   and glyph positioning code when enabling the filter.
+   *
+   *   The ClearType and Harmony rendering is applicable to glyph bitmaps
+   *   rendered through @FT_Render_Glyph, @FT_Load_Glyph, @FT_Load_Char, and
+   *   @FT_Glyph_To_Bitmap, when @FT_RENDER_MODE_LCD or @FT_RENDER_MODE_LCD_V
+   *   is specified.  This API does not control @FT_Outline_Render and
+   *   @FT_Outline_Get_Bitmap.
+   *
+   *   The described algorithms can completely remove color artefacts when
+   *   combined with gamma-corrected alpha blending in linear space.  Each of
+   *   the 3~alpha values (subpixels) must by independently used to blend one
+   *   color channel.  That is, red alpha blends the red channel of the text
+   *   color with the red channel of the background pixel.

+   *   driver can be registered and prioritized.  Additionally, some module
+   *   properties can also be controlled.

+   *   Here is a list of existing values of the `module_name` field in the
+   *   @FT_Module_Class structure.

+   *
+   * This file is used to define the FreeType module error codes.
+   *
+   * If the macro `FT_CONFIG_OPTION_USE_MODULE_ERRORS` in `ftoption.h` is
+   * set, the lower byte of an error value identifies the error code as
+   * usual.  In addition, the higher byte identifies the module.  For
+   * example, the error `FT_Err_Invalid_File_Format` has value 0x0003, the
+   * error `TT_Err_Invalid_File_Format` has value 0x1303, the error
+   * `T1_Err_Invalid_File_Format` has value 0x1403, etc.
+   *
+   * Note that `FT_Err_Ok`, `TT_Err_Ok`, etc. are always equal to zero,
+   * including the high byte.
+   *
+   * If `FT_CONFIG_OPTION_USE_MODULE_ERRORS` isn't set, the higher byte of an
+   * error value is set to zero.
+   *
+   * To hide the various `XXX_Err_` prefixes in the source code, FreeType
+   * provides some macros in `fttypes.h`.
+   *
+   *   FT_ERR( err )
+   *
+   *     Add current error module prefix (as defined with the `FT_ERR_PREFIX`
+   *     macro) to `err`.  For example, in the BDF module the line
+   *
+   *     ```
+   *       error = FT_ERR( Invalid_Outline );
+   *     ```
+   *
+   *     expands to
+   *
+   *     ```
+   *       error = BDF_Err_Invalid_Outline;
+   *     ```
+   *
+   *     For simplicity, you can always use `FT_Err_Ok` directly instead of
+   *     `FT_ERR( Ok )`.
+   *
+   *   FT_ERR_EQ( errcode, err )
+   *   FT_ERR_NEQ( errcode, err )
+   *
+   *     Compare error code `errcode` with the error `err` for equality and
+   *     inequality, respectively.  Example:
+   *
+   *     ```
+   *       if ( FT_ERR_EQ( error, Invalid_Outline ) )
+   *         ...
+   *     ```
+   *
+   *     Using this macro you don't have to think about error prefixes.  Of
+   *     course, if module errors are not active, the above example is the
+   *     same as
+   *
+   *     ```
+   *       if ( error == FT_Err_Invalid_Outline )
+   *         ...
+   *     ```
+   *
+   *   FT_ERROR_BASE( errcode )
+   *   FT_ERROR_MODULE( errcode )
+   *
+   *     Get base error and module error code, respectively.
+   *
+   * It can also be used to create a module error message table easily with
+   * something like
+   *
+   * ```
+   *   #undef FTMODERR_H_
+   *   #define FT_MODERRDEF( e, v, s )  { FT_Mod_Err_ ## e, s },
+   *   #define FT_MODERR_START_LIST     {
+   *   #define FT_MODERR_END_LIST       { 0, 0 } };

-   * @title:
-   *   The TrueType driver
-   *
-   * @abstract:
-   *   Controlling the TrueType driver module.
-   *
-   * @description:
-   *   While FreeType's TrueType driver doesn't expose API functions by
-   *   itself, it is possible to control its behaviour with @FT_Property_Set
-   *   and @FT_Property_Get.  The following lists the available properties
-   *   together with the necessary macros and structures.
-   *
-   *   The TrueType driver's module name is `truetype'.
-   *
-   *   We start with a list of definitions, kindly provided by Greg
-   *   Hitchcock.
-   *
-   *   _Bi-Level_ _Rendering_
-   *
-   *   Monochromatic rendering, exclusively used in the early days of
-   *   TrueType by both Apple and Microsoft.  Microsoft's GDI interface
-   *   supported hinting of the right-side bearing point, such that the
-   *   advance width could be non-linear.  Most often this was done to
-   *   achieve some level of glyph symmetry.  To enable reasonable
-   *   performance (e.g., not having to run hinting on all glyphs just to
-   *   get the widths) there was a bit in the head table indicating if the
-   *   side bearing was hinted, and additional tables, `hdmx' and `LTSH', to
-   *   cache hinting widths across multiple sizes and device aspect ratios.
-   *
-   *   _Font_ _Smoothing_
-   *
-   *   Microsoft's GDI implementation of anti-aliasing.  Not traditional
-   *   anti-aliasing as the outlines were hinted before the sampling.  The
-   *   widths matched the bi-level rendering.
-   *
-   *   _ClearType_ _Rendering_
-   *
-   *   Technique that uses physical subpixels to improve rendering on LCD
-   *   (and other) displays.  Because of the higher resolution, many methods
-   *   of improving symmetry in glyphs through hinting the right-side
-   *   bearing were no longer necessary.  This lead to what GDI calls
-   *   `natural widths' ClearType, see
-   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec21.  Since hinting
-   *   has extra resolution, most non-linearity went away, but it is still
-   *   possible for hints to change the advance widths in this mode.
-   *
-   *   _ClearType_ _Compatible_ _Widths_
-   *
-   *   One of the earliest challenges with ClearType was allowing the
-   *   implementation in GDI to be selected without requiring all UI and
-   *   documents to reflow.  To address this, a compatible method of
-   *   rendering ClearType was added where the font hints are executed once
-   *   to determine the width in bi-level rendering, and then re-run in
-   *   ClearType, with the difference in widths being absorbed in the font
-   *   hints for ClearType (mostly in the white space of hints); see
-   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec20.  Somewhat by
-   *   definition, compatible width ClearType allows for non-linear widths,
-   *   but only when the bi-level version has non-linear widths.
-   *
-   *   _ClearType_ _Subpixel_ _Positioning_
-   *
-   *   One of the nice benefits of ClearType is the ability to more crisply
-   *   display fractional widths; unfortunately, the GDI model of integer
-   *   bitmaps did not support this.  However, the WPF and Direct Write
-   *   frameworks do support fractional widths.  DWrite calls this `natural
-   *   mode', not to be confused with GDI's `natural widths'.  Subpixel
-   *   positioning, in the current implementation of Direct Write,
-   *   unfortunately does not support hinted advance widths, see
-   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec22.  Note that the
-   *   TrueType interpreter fully allows the advance width to be adjusted in
-   *   this mode, just the DWrite client will ignore those changes.
-   *
-   *   _ClearType_ _Backwards_ _Compatibility_
-   *
-   *   This is a set of exceptions made in the TrueType interpreter to
-   *   minimize hinting techniques that were problematic with the extra
-   *   resolution of ClearType; see
-   *   http://www.beatstamm.com/typography/RTRCh4.htm#Sec1 and
-   *   http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
-   *   This technique is not to be confused with ClearType compatible
-   *   widths.  ClearType backwards compatibility has no direct impact on
-   *   changing advance widths, but there might be an indirect impact on
-   *   disabling some deltas.  This could be worked around in backwards
-   *   compatibility mode.
-   *
-   *   _Native_ _ClearType_ _Mode_
-   *
-   *   (Not to be confused with `natural widths'.)  This mode removes all
-   *   the exceptions in the TrueType interpreter when running with
-   *   ClearType.  Any issues on widths would still apply, though.

-   * @property:
-   *   interpreter-version
-   *
-   * @description:
-   *   Currently, two versions are available, representing the bytecode
-   *   interpreter with and without subpixel hinting support,
-   *   respectively.  The default is subpixel support if
-   *   TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel
-   *   support otherwise (since it isn't available then).
-   *
-   *   If subpixel hinting is on, many TrueType bytecode instructions behave
-   *   differently compared to B/W or grayscale rendering (except if `native
-   *   ClearType' is selected by the font).  The main idea is to render at a
-   *   much increased horizontal resolution, then sampling down the created
-   *   output to subpixel precision.  However, many older fonts are not
-   *   suited to this and must be specially taken care of by applying
-   *   (hardcoded) font-specific tweaks.
-   *
-   *   Details on subpixel hinting and some of the necessary tweaks can be
-   *   found in Greg Hitchcock's whitepaper at
-   *   `http://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'.
-   *
-   *   The following example code demonstrates how to activate subpixel
-   *   hinting (omitting the error handling).
-   *
-   *   {
-   *     FT_Library  library;
-   *     FT_Face     face;
-   *     FT_UInt     interpreter_version = TT_INTERPRETER_VERSION_38;

-   *                               &interpreter_version );
-   *   }
-   *

-   *   This property can be used with @FT_Property_Get also.

-   * @enum:
-   *   TT_INTERPRETER_VERSION_XXX
-   *
-   * @description:
-   *   A list of constants used for the @interpreter-version property to
-   *   select the hinting engine for Truetype fonts.
-   *
-   *   The numeric value in the constant names represents the version
-   *   number as returned by the `GETINFO' bytecode instruction.
-   *
-   * @values:
-   *   TT_INTERPRETER_VERSION_35 ::
-   *     Version~35 corresponds to MS rasterizer v.1.7 as used e.g. in
-   *     Windows~98; only grayscale and B/W rasterizing is supported.
-   *
-   *   TT_INTERPRETER_VERSION_38 ::
-   *     Version~38 corresponds to MS rasterizer v.1.9; it is roughly
-   *     equivalent to the hinting provided by DirectWrite ClearType (as
-   *     can be found, for example, in the Internet Explorer~9 running on
-   *     Windows~7).
-   *
-   * @note:
-   *   This property controls the behaviour of the bytecode interpreter
-   *   and thus how outlines get hinted.  It does *not* control how glyph
-   *   get rasterized!  In particular, it does not control subpixel color
-   *   filtering.
-   *
-   *   If FreeType has not been compiled with configuration option
-   *   FT_CONFIG_OPTION_SUBPIXEL_HINTING, selecting version~38 causes an
-   *   `FT_Err_Unimplemented_Feature' error.
-   *
-   *   Depending on the graphics framework, Microsoft uses different
-   *   bytecode and rendering engines.  As a consequence, the version
-   *   numbers returned by a call to the `GETINFO' bytecode instruction are
-   *   more convoluted than desired.
-   *
-   *   Here are two tables that try to shed some light on the possible
-   *   values for the MS rasterizer engine, together with the additional

-   *   feature is `symmetric smoothing'.  `Classic ClearType' is the
-   *   original algorithm used before introducing a modified version in
-   *   Win~XP.  Another name for v1.6's grayscale rendering is `font
-   *   smoothing', and `Color ClearType' is sometimes also called `DWrite
-   *   ClearType'.  To differentiate between today's Color ClearType and the
-   *   earlier ClearType variant with B/W rendering along the vertical axis,
-   *   the latter is sometimes called `GDI ClearType'.
-   *
-   *   `Normal' and `high' sampling describe the (virtual) resolution to
-   *   access the rasterized outline after the hinting process.  `Normal'
-   *   means 1 sample per grid line (i.e., B/W).  In the current Microsoft
-   *   implementation, `high' means an extra virtual resolution of 16x16 (or
-   *   16x1) grid lines per pixel for bytecode instructions like `MIRP'.
-   *   After hinting, these 16 grid lines are mapped to 6x5 (or 6x1) grid
-   *   lines for color filtering if Color ClearType is activated.
-   *
-   *   Note that `Gray ClearType' is essentially the same as v1.6's
-   *   grayscale rendering.  However, the GETINFO instruction handles it
-   *   differently: v1.6 returns bit~12 (hinting for grayscale), while v2.1
-   *   returns bits~13 (hinting for ClearType), 18 (symmetrical smoothing),
-   *   and~19 (Gray ClearType).  Also, this mode respects bits 2 and~3 for
-   *   the version~1 gasp table exclusively (like Color ClearType), while
-   *   v1.6 only respects the values of version~0 (bits 0 and~1).
-   *
-   *   FreeType doesn't provide all capabilities of the most recent
-   *   ClearType incarnation, thus we identify our subpixel support as
-   *   version~38.

+   * A small technical note regarding automatic hinting in order to clarify
+   * this module interface.
+   *
+   * An automatic hinter might compute two kinds of data for a given face:
+   *
+   * - global hints: Usually some metrics that describe global properties
+   *                 of the face.  It is computed by scanning more or less
+   *                 aggressively the glyphs in the face, and thus can be
+   *                 very slow to compute (even if the size of global hints
+   *                 is really small).
+   *
+   * - glyph hints: These describe some important features of the glyph
+   *                 outline, as well as how to align them.  They are
+   *                 generally much faster to compute than global hints.
+   *
+   * The current FreeType auto-hinter does a pretty good job while performing
+   * fast computations for both global and glyph hints.  However, we might be
+   * interested in introducing more complex and powerful algorithms in the
+   * future, like the one described in the John D. Hobby paper, which
+   * unfortunately requires a lot more horsepower.
+   *
+   * Because a sufficiently sophisticated font management system would
+   * typically implement an LRU cache of opened face objects to reduce memory
+   * usage, it is a good idea to be able to avoid recomputing global hints
+   * every time the same face is re-opened.
+   *
+   * We thus provide the ability to cache global hints outside of the face
+   * object, in order to speed up font re-opening time.  Of course, this
+   * feature is purely optional, so most client programs won't even notice
+   * it.
+   *
+   * I initially thought that it would be a good idea to cache the glyph
+   * hints too.  However, my general idea now is that if you really need to
+   * cache these too, you are simply in need of a new font format, where all
+   * this information could be stored within the font file and decoded on the
+   * fly.

+   *     loaded from the font.  Only used by the convenience functions.
+   *
+   *   transform_flags ::
+   *     Some flags used to classify the transform.  Only used by the
+   *     convenience functions.
+   *
+   *   services ::
+   *     A cache for frequently used services.  It should be only accessed
+   *     with the macro `FT_FACE_LOOKUP_SERVICE`.
+   *
+   *   incremental_interface ::
+   *     If non-null, the interface through which glyph data and metrics are
+   *     loaded incrementally for faces that do not provide all of this data
+   *     when first opened.  This field exists only if
+   *     @FT_CONFIG_OPTION_INCREMENTAL is defined.
+   *
+   *   no_stem_darkening ::
+   *     Overrides the module-level default, see @stem-darkening[cff], for
+   *     example.  FALSE and TRUE toggle stem darkening on and off,
+   *     respectively, value~-1 means to use the module/driver default.
+   *
+   *   random_seed ::
+   *     If positive, override the seed value for the CFF 'random' operator.
+   *     Value~0 means to use the font's value.  Value~-1 means to use the
+   *     CFF driver's default.
+   *
+   *   lcd_weights ::
+   *   lcd_filter_func ::
+   *     These fields specify the LCD filtering weights and callback function
+   *     for ClearType-style subpixel rendering.
+   *
+   *   refcount ::
+   *     A counter initialized to~1 at the time an @FT_Face structure is
+   *     created.  @FT_Reference_Face increments this counter, and
+   *     @FT_Done_Face only destroys a face if the counter is~1, otherwise it
+   *     simply decrements it.

-     * agnostic of OpenType features after the feature analysis has been
-     * completed: The engine then simply receives a glyph index and returns a
-     * hinted and usually rendered glyph.
-     *
-     * Consider the superscript feature of font `pala.ttf': Some of the
-     * glyphs are `real', this is, they have a zero vertical offset, but
-     * most of them are small caps glyphs shifted up to the superscript
-     * position (this is, the `sups' feature is present in both the GSUB and
-     * GPOS tables).  The code for blue zones computation actually uses a
-     * feature's y offset so that the `real' glyphs get correct hints.  But
-     * later on it is impossible to decide whether a glyph index belongs to,
-     * say, the small caps or superscript feature.
-     *
-     * For this reason, we don't assign a style to a glyph if the current
-     * feature covers the glyph in both the GSUB and the GPOS tables.  This
-     * is quite a broad condition, assuming that
-     *
-     *   (a) glyphs that get used in multiple features are present in a
-     *       feature without vertical shift,
-     *
-     * and
-     *
-     *   (b) a feature's GPOS data really moves the glyph vertically.
-     *
-     * Not fulfilling condition (a) makes a font larger; it would also
-     * reduce the number of glyphs that could be addressed directly without
-     * using OpenType features, so this assumption is rather strong.
-     *
-     * Condition (b) is much weaker, and there might be glyphs which get
-     * missed.  However, the OpenType features we are going to handle are
-     * primarily located in GSUB, and HarfBuzz doesn't provide an API to
-     * directly get the necessary information from the GPOS table.  A
-     * possible solution might be to directly parse the GPOS table to find
-     * out whether a glyph gets shifted vertically, but this is something I
-     * would like to avoid if not really necessary.
-     *
-     * Note that we don't follow this logic for the default coverage.
-     * Complex scripts like Devanagari have mandatory GPOS features to
-     * position many glyph elements, using mark-to-base or mark-to-ligature
-     * tables; the number of glyphs missed due to condition (b) would be far
-     * too large.

+   * debugging of the FreeType engine.  Its main purpose is in assertion
+   * checking, tracing, and error detection.
+   *
+   * There are now three debugging modes:
+   *
+   * - trace mode
+   *
+   *   Error and trace messages are sent to the log file (which can be the
+   *   standard error output).
+   *
+   * - error mode
+   *
+   *   Only error messages are generated.
+   *
+   * - release mode:
+   *
+   *   No error message is sent or generated.  The code is free from any
+   *   debugging parts.

-   * by `BlueValues', `OtherBlues', `FamilyBlues', and `FamilyOtherBlues'.
-   * Each zone is defined by a top and bottom edge in character space.
-   * Further, each zone is either a top zone or a bottom zone, as recorded
-   * by `bottomZone'.
-   *
-   * The maximum number of `BlueValues' and `FamilyBlues' is 7 each.
-   * However, these are combined to produce a total of 7 zones.
-   * Similarly, the maximum number of `OtherBlues' and `FamilyOtherBlues'
-   * is 5 and these are combined to produce an additional 5 zones.
-   *
-   * Blue zones are used to `capture' hints and force them to a common

-   * `dsFlatEdge'.  Except for this value, a `CF2_Blues' object could be
-   * constructed independently of scaling.  Construction may occur once
-   * the matrix is known.  Other features implemented in the Capture
-   * method are overshoot suppression, overshoot enforcement, and Blue
-   * Boost.
-   *
-   * Capture is determined by `BlueValues' and `OtherBlues', but the
-   * alignment point may be adjusted to the scaled flat edge of
-   * `FamilyBlues' or `FamilyOtherBlues'.  No alignment is done to the
-   * curved edge of a zone.

-   * A poor-man error facility.
-   *
-   * This code being written in vanilla C, doesn't have the luxury of a
-   * language-supported exception mechanism such as the one available in
-   * Java.  Instead, we are stuck with using error codes that must be
-   * carefully managed and preserved.  However, it is convenient for us to
-   * model our error mechanism on a Java-like exception mechanism.
-   * When we assign an error code we are thus `throwing' an error.
-   *
-   * The perservation of an error code is done by coding convention.
-   * Upon a function call if the error code is anything other than
-   * `FT_Err_Ok', which is guaranteed to be zero, we
-   * will return without altering that error.  This will allow the
-   * error to propogate and be handled at the appropriate location in
-   * the code.
-   *
-   * This allows a style of code where the error code is initialized
-   * up front and a block of calls are made with the error code only
-   * being checked after the block.  If a new error occurs, the original
-   * error will be preserved and a functional no-op should result in any
-   * subsequent function that has an initial error code not equal to
-   * `FT_Err_Ok'.
-   *
-   * Errors are encoded by calling the `FT_THROW' macro.  For example,
-   *
-   * {
-   *   FT_Error  e;
-   *
-   *
-   *   ...
-   *   e = FT_THROW( Out_Of_Memory );

+Name: zlib
+Short Name: zlib
+URL: http://zlib.net/
+Version: 1.2.13
+License: see `zlib.h`
+
+Description:
+"A massively spiffy yet delicately unobtrusive compression library."
+
+'zlib' is a free, general-purpose, legally unencumbered lossless
+data-compression library.  'zlib' implements the "deflate" compression
+algorithm described by RFC 1951, which combines the LZ77 (Lempel-Ziv)
+algorithm with Huffman coding.  zlib also implements the zlib (RFC 1950) and
+gzip (RFC 1952) wrapper formats.
+
+Local Modifications:
+The files in this directory have been prepared as follows.
+
+ - Take the unmodified source code files from the zlib distribution that are
+   included by `ftgzip.c`.
+ - Copy `zconf.h` to `ftzconf.h` (which stays unmodified otherwise).
+ - Run zlib's `zlib2ansi` script on all `.c` files.
+ - Apply the diff file(s) in the `patches` folder.

+  Polynomials over GF(2) are represented in binary, one bit per coefficient,

+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder. The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by x
+  (which is shifting right by one and adding x^32 mod p if the bit shifted out
+  is a one). We start with the highest power (least significant bit) of q and
+  repeat for all eight bits of q.
+
+  The table is simply the CRC of all possible eight bit values. This is all the

-   Notes beyond the 1.93a appnote.txt:
-
-   1. Distance pointers never point before the beginning of the output
-      stream.
-   2. Distance pointers can point back across blocks, up to 32k away.
-   3. There is an implied maximum of 7 bits for the bit length table and
-      15 bits for the actual data.
-   4. If only one code exists, then it is encoded using one bit.  (Zero
-      would be more efficient, but perhaps a little confusing.)  If two
-      codes exist, they are coded using one bit each (0 and 1).
-   5. There is no way of sending zero distance codes--a dummy must be
-      sent if there are none.  (History: a pre 2.0 version of PKZIP would
-      store blocks with no distance codes, but this was discovered to be
-      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
-      zero distance codes, which is sent as one code of zero bits in
-      length.
-   6. There are up to 286 literal/length codes.  Code 256 represents the
-      end-of-block.  Note however that the static length tree defines
-      288 codes just to fill out the Huffman codes.  Codes 286 and 287
-      cannot be used though, since there is no length base or extra bits
-      defined for them.  Similarily, there are up to 30 distance codes.
-      However, static trees define 32 codes (all 5 bits) to fill out the
-      Huffman codes, but the last two had better not show up in the data.
-   7. Unzip can check dynamic Huffman blocks for complete code sets.
-      The exception is that a single code would not be complete (see #4).
-   8. The five bits following the block type is really the number of
-      literal codes sent minus 257.
-   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
-      (1+6+6).  Therefore, to output three times the length, you output
-      three codes (1+1+1), whereas to output four times the same length,
-      you only need two codes (1+3).  Hmm.
-  10. In the tree reconstruction algorithm, Code = Code + Increment
-      only if BitLength(i) is not zero.  (Pretty obvious.)
-  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
-  12. Note: length code 284 can represent 227-258, but length code 285
-      really is 258.  The last length deserves its own, short code
-      since it gets used a lot in very redundant files.  The length
-      258 is special since 258 - 3 (the min match length) is 255.
-  13. The literal/length and distance code bit lengths are read as a
-      single stream of lengths.  It is possible (and advantageous) for
-      a repeat code (16, 17, or 18) to go across the boundary between
-      the two sets of lengths.

+   Decode literal, length, and distance codes and write out the resulting
+   literal and match bytes until either not enough input or output is
+   available, an end-of-block is encountered, or a data error is encountered.
+   When large enough input and output buffers are supplied to inflate(), for
+   example, a 16K input buffer and a 64K output buffer, more than 95% of the
+   inflate execution time is spent in this routine.
+
+   Entry assumptions:
+
+        state->mode == LEN
+        strm->avail_in >= 6
+        strm->avail_out >= 258
+        start >= strm->avail_out
+        state->bits < 8
+
+   On return, state->mode is one of:
+
+        LEN -- ran out of enough output space or enough available input
+        TYPE -- reached end of block code, inflate() to interpret next block
+        BAD -- error in block data
+
+   Notes:
+
+    - The maximum input bits used by a length/distance pair is 15 bits for the
+      length code, 5 bits for the length extra, 15 bits for the distance code,
+      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
+      Therefore if strm->avail_in >= 6, then there is enough input to avoid
+      checking for available input while decoding.
+
+    - The maximum bytes that a single length/distance pair can output is 258
+      bytes, which is the maximum length that can be coded.  inflate_fast()
+      requires strm->avail_out >= 258 for each loop to avoid checking for
+      output space.

  */
 
+/*
+ * Change history:
+ *
+ * 1.2.beta0    24 Nov 2002
+ * - First version -- complete rewrite of inflate to simplify code, avoid
+ *   creation of window when not needed, minimize use of window when it is
+ *   needed, make inffast.c even faster, implement gzip decoding, and to
+ *   improve code readability and style over the previous zlib inflate code
+ *
+ * 1.2.beta1    25 Nov 2002
+ * - Use pointers for available input and output checking in inffast.c
+ * - Remove input and output counters in inffast.c
+ * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
+ * - Remove unnecessary second byte pull from length extra in inffast.c
+ * - Unroll direct copy to three copies per loop in inffast.c
+ *
+ * 1.2.beta2    4 Dec 2002
+ * - Change external routine names to reduce potential conflicts
+ * - Correct filename to inffixed.h for fixed tables in inflate.c
+ * - Make hbuf[] unsigned char to match parameter type in inflate.c
+ * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
+ *   to avoid negation problem on Alphas (64 bit) in inflate.c
+ *
+ * 1.2.beta3    22 Dec 2002
+ * - Add comments on state->bits assertion in inffast.c
+ * - Add comments on op field in inftrees.h
+ * - Fix bug in reuse of allocated window after inflateReset()
+ * - Remove bit fields--back to byte structure for speed
+ * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
+ * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
+ * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
+ * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
+ * - Use local copies of stream next and avail values, as well as local bit
+ *   buffer and bit count in inflate()--for speed when inflate_fast() not used
+ *
+ * 1.2.beta4    1 Jan 2003
+ * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
+ * - Move a comment on output buffer sizes from inffast.c to inflate.c
+ * - Add comments in inffast.c to introduce the inflate_fast() routine
+ * - Rearrange window copies in inflate_fast() for speed and simplification
+ * - Unroll last copy for window match in inflate_fast()
+ * - Use local copies of window variables in inflate_fast() for speed
+ * - Pull out common wnext == 0 case for speed in inflate_fast()
+ * - Make op and len in inflate_fast() unsigned for consistency
+ * - Add FAR to lcode and dcode declarations in inflate_fast()
+ * - Simplified bad distance check in inflate_fast()
+ * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
+ *   source file infback.c to provide a call-back interface to inflate for
+ *   programs like gzip and unzip -- uses window as output buffer to avoid
+ *   window copying
+ *
+ * 1.2.beta5    1 Jan 2003
+ * - Improved inflateBack() interface to allow the caller to provide initial
+ *   input in strm.
+ * - Fixed stored blocks bug in inflateBack()
+ *
+ * 1.2.beta6    4 Jan 2003
+ * - Added comments in inffast.c on effectiveness of POSTINC
+ * - Typecasting all around to reduce compiler warnings
+ * - Changed loops from while (1) or do {} while (1) to for (;;), again to
+ *   make compilers happy
+ * - Changed type of window in inflateBackInit() to unsigned char *
+ *
+ * 1.2.beta7    27 Jan 2003
+ * - Changed many types to unsigned or unsigned short to avoid warnings
+ * - Added inflateCopy() function
+ *
+ * 1.2.0        9 Mar 2003
+ * - Changed inflateBack() interface to provide separate opaque descriptors
+ *   for the in() and out() functions
+ * - Changed inflateBack() argument and in_func typedef to swap the length
+ *   and buffer address return values for the input function
+ * - Check next_in and next_out for Z_NULL on entry to inflate()
+ *
+ * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

+   inflate() uses a state machine to process as much input data and generate as
+   much output data as possible before returning.  The state machine is
+   structured roughly as follows:
+
+    for (;;) switch (state) {
+    ...
+    case STATEn:
+        if (not enough input data or output space to make progress)
+            return;
+        ... make progress ...
+        state = STATEm;
         break;
-      }
-      Tracev((stderr, "inflate: zlib check ok\n"));
-      z->state->mode = DONE;
-    case DONE:
-      return Z_STREAM_END;
-    case BAD:
-      return Z_DATA_ERROR;
-    default:
-      return Z_STREAM_ERROR;
-  }
-#ifdef NEED_DUMMY_RETURN
-  return Z_STREAM_ERROR;  /* Some dumb compilers complain without this */
+    ...
+    }
+
+   so when inflate() is called again, the same case is attempted again, and
+   if the appropriate resources are provided, the machine proceeds to the
+   next state.  The NEEDBITS() macro is usually the way the state evaluates
+   whether it can proceed or should return.  NEEDBITS() does the return if
+   the requested bits are not available.  The typical use of the BITS macros
+   is:
+
+        NEEDBITS(n);
+        ... do something with BITS(n) ...
+        DROPBITS(n);
+
+   where NEEDBITS(n) either returns from inflate() if there isn't enough
+   input left to load n bits into the accumulator, or it continues.  BITS(n)
+   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
+   the low n bits off the accumulator.  INITBITS() clears the accumulator
+   and sets the number of available bits to zero.  BYTEBITS() discards just
+   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
+   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
+
+   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
+   if there is no input available.  The decoding of variable length codes uses
+   PULLBYTE() directly in order to pull just enough bytes to decode the next
+   code, and no more.
+
+   Some states loop until they get enough input, making sure that enough
+   state information is maintained to continue the loop where it left off
+   if NEEDBITS() returns in the loop.  For example, want, need, and keep
+   would all have to actually be part of the saved state in case NEEDBITS()
+   returns:
+
+    case STATEw:
+        while (want < need) {
+            NEEDBITS(n);
+            keep[want++] = BITS(n);
+            DROPBITS(n);
+        }
+        state = STATEx;
+    case STATEx:
+
+   As shown above, if the next state is also the next case, then the break
+   is omitted.
+
+   A state may also return if there is not enough output space available to
+   complete that state.  Those states are copying stored data, writing a
+   literal byte, and copying a matching string.
+
+   When returning, a "goto inf_leave" is used to update the total counters,
+   update the check value, and determine whether any progress has been made
+   during that inflate() call in order to return the proper return code.
+   Progress is defined as a change in either strm->avail_in or strm->avail_out.
+   When there is a window, goto inf_leave will update the window with the last
+   output written.  If a goto inf_leave occurs in the middle of decompression
+   and there is no window currently, goto inf_leave will create one and copy
+   output to the window for the next call of inflate().
+
+   In this implementation, the flush parameter of inflate() only affects the
+   return code (per zlib.h).  inflate() always writes as much as possible to
+   strm->next_out, given the space available and the provided input--the effect
+   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
+   the allocation of and copying into a sliding window until necessary, which
+   provides the effect documented in zlib.h for Z_FINISH when the entire input
+   stream available.  So the only thing the flush parameter actually does is:
+   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
+   will return Z_BUF_ERROR if it has not reached the end of the stream.

-   Huffman code decoding is performed using a multi-level table lookup.
-   The fastest way to decode is to simply build a lookup table whose
-   size is determined by the longest code.  However, the time it takes
-   to build this table can also be a factor if the data being decoded
-   is not very long.  The most common codes are necessarily the
-   shortest codes, so those codes dominate the decoding time, and hence
-   the speed.  The idea is you can have a shorter table that decodes the
-   shorter, more probable codes, and then point to subsidiary tables for
-   the longer codes.  The time it costs to decode the longer codes is
-   then traded against the time it takes to make longer tables.
-
-   This results of this trade are in the variables lbits and dbits
-   below.  lbits is the number of bits the first level table for literal/
-   length codes can decode in one step, and dbits is the same thing for
-   the distance codes.  Subsequent tables are also less than or equal to
-   those sizes.  These values may be adjusted either when all of the
-   codes are shorter than that, in which case the longest code length in
-   bits is used, or when the shortest code is *longer* than the requested
-   table size, in which case the length of the shortest code in bits is
-   used.
-
-   There are two different values for the two tables, since they code a
-   different number of possibilities each.  The literal/length table
-   codes 286 possible values, or in a flat code, a little over eight
-   bits.  The distance table codes 30 possible values, or a little less
-   than five bits, flat.  The optimum values for speed end up being
-   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
-   The optimum values may differ though from machine to machine, and
-   possibly even between compilers.  Your mileage may vary.

+
+    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
+  decide how much data to accumulate before producing output, in order to
+  maximize compression.
 
     If the parameter flush is set to Z_SYNC_FLUSH, all pending output is

-  that the decompressor can get all input data available so far. (In particular

+  completes the current deflate block and follows it with an empty stored block
+  that is three bits plus filler bits to the next byte, followed by four bytes
+  (00 00 ff ff).
+
+    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
+  output buffer, but the output is not aligned to a byte boundary.  All of the
+  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
+  This completes the current deflate block and follows it with an empty fixed
+  codes block that is 10 bits long.  This assures that enough bytes are output
+  in order for the decompressor to finish the block before the empty fixed
+  codes block.
+
+    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
+  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
+  seven bits of the current block are held to be written as the next byte after
+  the next deflate block is completed.  In this case, the decompressor may not

+  the data provided so far to the compressor.  It may need to wait for the next
+  block to be emitted.  This is for advanced applications that need to control
+  the emission of deflate blocks.
 
     If flush is set to Z_FULL_FLUSH, all output is flushed as with
   Z_SYNC_FLUSH, and the compression state is reset so that decompression can
   restart from this point if previous compressed data has been damaged or if

+
+    The Z_BLOCK option assists in appending to or combining deflate streams.

+  inflate() is currently decoding the last block in the deflate stream, plus
+  128 if inflate() returned immediately after decoding an end-of-block code or

+  unused bits may in general be greater than seven, except when bit 7 of
+  data_type is set, in which case the number of unused bits will be less than
+  eight.  data_type is set as noted here every time inflate() returns for all
+  flush options, and so can be used to determine the amount of currently
+  consumed input in bits.
+
+    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
+  end of each deflate block header is reached, before any actual data in that
+  block is decoded.  This allows the caller to determine the length of the
+  deflate block header for later use in random access within a deflate block.

     inflate() should normally be called until it returns Z_STREAM_END or an
-  error. However if all decompression is to be performed in a single step
-  (a single call of inflate), the parameter flush should be set to
-  Z_FINISH. In this case all pending input is processed and all pending
-  output is flushed; avail_out must be large enough to hold all the
-  uncompressed data. (The size of the uncompressed data may have been saved
-  by the compressor for this purpose.) The next operation on this stream must
-  be inflateEnd to deallocate the decompression state. The use of Z_FINISH
-  is never required, but can be used to inform inflate that a faster routine
-  may be used for the single inflate() call.
-
-     If a preset dictionary is needed at this point (see inflateSetDictionary
-  below), inflate sets strm-adler to the adler32 checksum of the
-  dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise
-  it sets strm->adler to the adler32 checksum of all output produced
-  so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or
-  an error code as described below. At the end of the stream, inflate()

+
+     In this implementation, inflate() always flushes as much output as

+
+    inflate() can decompress and check either zlib-wrapped or gzip-wrapped

+   size is given as input, inflate() will return with the error code

+
+     windowBits can also be zero to request that inflate use the window size in

+
+     windowBits can also be -8..-15 for raw inflate.  In this case, -windowBits
+   determines the window size.  inflate() will then process raw deflate data,
+   not looking for a zlib or gzip header, not generating a check value, and not
+   looking for any check values for comparison at the end of the stream.  This
+   is for use with other formats that use the deflate compressed data format
+   such as zip.  Those formats provide their own check values.  If a custom
+   format is developed using the raw deflate format for compressed data, it is
+   recommended that a check value such as an Adler-32 or a CRC-32 be applied to
+   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
+   most applications, the zlib format should be used as is.  Note that comments
+   above on the use in deflateInit2() applies to the magnitude of windowBits.
+
+     windowBits can also be greater than 15 for optional gzip decoding.  Add
+   32 to windowBits to enable zlib and gzip decoding with automatic header
+   detection, or add 16 to decode only the gzip format (the zlib format will
+   return a Z_DATA_ERROR).  If a gzip stream is being decoded, strm->adler is a
+   CRC-32 instead of an Adler-32.  Unlike the gunzip utility and gzread() (see
+   below), inflate() will *not* automatically decode concatenated gzip members.

+   no gzip header information forthcoming.  Note that Z_BLOCK or Z_TREES can be
+   used to force inflate() to return immediately after header processing is
+   complete and before any actual data is decompressed.
+
+     The text, time, xflags, and os fields are filled in with the gzip header
+   contents.  hcrc is set to true if there is a header CRC.  (The header CRC
+   was valid if done is set to one.) If extra is not Z_NULL, then extra_max
+   contains the maximum number of bytes to write to extra.  Once done is true,
+   extra_len contains the actual extra field length, and extra contains the
+   extra field, or that field truncated if extra_max is less than extra_len.
+   If name is not Z_NULL, then up to name_max characters are written there,
+   terminated with a zero unless the length is greater than name_max.  If
+   comment is not Z_NULL, then up to comm_max characters are written there,
+   terminated with a zero unless the length is greater than comm_max.  When any
+   of extra, name, or comment are not Z_NULL and the respective field is not
+   present in the header, then that field is set to Z_NULL to signal its
+   absence.  This allows the use of deflateSetHeader() with the returned
+   structure to duplicate the header.  However if those fields are set to
+   allocated memory, then the application will need to save those pointers

+
+     If inflateGetHeader is not used, then the header information is simply

+     inflateBack() does a raw inflate with a single call using a call-back
+   interface for input and output.  This is potentially more efficient than
+   inflate() for file i/o applications, in that it avoids copying between the
+   output and the sliding window by simply making the window itself the output
+   buffer.  inflate() can be faster on modern CPUs when used with large
+   buffers.  inflateBack() trusts the application to not change the output
+   buffer passed by the output function, at least until inflateBack() returns.
+
+     inflateBackInit() must be called first to allocate the internal state
+   and to initialize the state with the user-provided window buffer.
+   inflateBack() may then be used multiple times to inflate a complete, raw
+   deflate stream with each call.  inflateBackEnd() is then called to free the
+   allocated state.
+
+     A raw deflate stream is one with no zlib or gzip header or trailer.
+   This routine would normally be used in a utility that reads zip or gzip
+   files and writes out uncompressed files.  The utility would decode the
+   header and process the trailer on its own, hence this routine expects only
+   the raw deflate stream to decompress.  This is different from the default
+   behavior of inflate(), which expects a zlib header and trailer around the
+   deflate stream.
+
+     inflateBack() uses two subroutines supplied by the caller that are then
+   called by inflateBack() for input and output.  inflateBack() calls those
+   routines until it reads a complete deflate stream and writes out all of the
+   uncompressed data, or until it encounters an error.  The function's
+   parameters and return types are defined above in the in_func and out_func
+   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
+   number of bytes of provided input, and a pointer to that input in buf.  If
+   there is no input available, in() must return zero -- buf is ignored in that
+   case -- and inflateBack() will return a buffer error.  inflateBack() will
+   call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].
+   out() should return zero on success, or non-zero on failure.  If out()
+   returns non-zero, inflateBack() will return with an error.  Neither in() nor
+   out() are permitted to change the contents of the window provided to
+   inflateBackInit(), which is also the buffer that out() uses to write from.
+   The length written by out() will be at most the window size.  Any non-zero
+   amount of input may be provided by in().
+
+     For convenience, inflateBack() can be provided input on the first call by
+   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
+   in() will be called.  Therefore strm->next_in must be initialized before
+   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
+   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
+   must also be initialized, and then if strm->avail_in is not zero, input will
+   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
+
+     The in_desc and out_desc parameters of inflateBack() is passed as the
+   first parameter of in() and out() respectively when they are called.  These
+   descriptors can be optionally used to pass any information that the caller-
+   supplied in() and out() functions need to do their job.
+
+     On return, inflateBack() will set strm->next_in and strm->avail_in to
+   pass back any unused input that was provided by the last in() call.  The
+   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
+   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
+   in the deflate stream (in which case strm->msg is set to indicate the nature
+   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
+   In the case of Z_BUF_ERROR, an input or output error can be distinguished
+   using strm->next_in which will be Z_NULL only if in() returned an error.  If
+   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
+   non-zero.  (in() will always be called before out(), so strm->next_in is
+   assured to be defined if out() returns non-zero.)  Note that inflateBack()
+   cannot return Z_OK.

+   *
+   *   Converting an outline into a bitmap is achieved in several steps:
+   *
+   *   1 - Decomposing the outline into successive `profiles'.  Each
+   *       profile is simply an array of scanline intersections on a given
+   *       dimension.  A profile's main attributes are
+   *
+   *       o its scanline position boundaries, i.e. `Ymin' and `Ymax'
+   *
+   *       o an array of intersection coordinates for each scanline
+   *         between `Ymin' and `Ymax'
+   *
+   *       o a direction, indicating whether it was built going `up' or
+   *         `down', as this is very important for filling rules
+   *
+   *       o its drop-out mode
+   *
+   *   2 - Sweeping the target map's scanlines in order to compute segment
+   *       `spans' which are then filled.  Additionally, this pass
+   *       performs drop-out control.
+   *
+   *   The outline data is parsed during step 1 only.  The profiles are
+   *   built from the bottom of the render pool, used as a stack.  The
+   *   following graphics shows the profile list under construction:

+   *   The top of the profile stack is kept in the `top' variable.
+   *
+   *   As you can see, a profile record is pushed on top of the render
+   *   pool, which is then followed by its coordinates/intersections.  If
+   *   a change of direction is detected in the outline, a new profile is
+   *   generated until the end of the outline.
+   *
+   *   Note that when all profiles have been generated, the function
+   *   Finalize_Profile_Table() is used to record, for each profile, its
+   *   bottom-most scanline as well as the scanline above its upmost
+   *   boundary.  These positions are called `y-turns' because they (sort

+   *
+   * A brief technical overview of how the BSDF rasterizer works
+   * -----------------------------------------------------------
+   *
+   * [Notes]:
+   *   * SDF stands for Signed Distance Field everywhere.
+   *
+   *   * BSDF stands for Bitmap to Signed Distance Field rasterizer.
+   *
+   *   * This renderer converts rasterized bitmaps to SDF.  There is another
+   *     renderer called 'sdf', which generates SDF directly from outlines;
+   *     see file `ftsdf.c` for more.
+   *
+   *   * The idea of generating SDF from bitmaps is taken from two research
+   *     papers, where one is dependent on the other:
+   *
+   *     - Per-Erik Danielsson: Euclidean Distance Mapping
+   *       http://webstaff.itn.liu.se/~stegu/JFA/Danielsson.pdf
+   *
+   *       From this paper we use the eight-point sequential Euclidean
+   *       distance mapping (8SED).  This is the heart of the process used
+   *       in this rasterizer.
+   *
+   *     - Stefan Gustavson, Robin Strand: Anti-aliased Euclidean distance transform.
+   *       http://weber.itn.liu.se/~stegu/aadist/edtaa_preprint.pdf
+   *
+   *       The original 8SED algorithm discards the pixels' alpha values,
+   *       which can contain information about the actual outline of the
+   *       glyph.  This paper takes advantage of those alpha values and
+   *       approximates outline pretty accurately.
+   *
+   *   * This rasterizer also works for monochrome bitmaps.  However, the
+   *     result is not as accurate since we don't have any way to
+   *     approximate outlines from binary bitmaps.
+   *
+   * ========================================================================
+   *
+   * Generating SDF from bitmap is done in several steps.
+   *
+   * (1) The only information we have is the bitmap itself.  It can
+   *     be monochrome or anti-aliased.  If it is anti-aliased, pixel values
+   *     are nothing but coverage values.  These coverage values can be used
+   *     to extract information about the outline of the image.  For
+   *     example, if the pixel's alpha value is 0.5, then we can safely
+   *     assume that the outline passes through the center of the pixel.
+   *
+   * (2) Find edge pixels in the bitmap (see `bsdf_is_edge` for more).  For
+   *     all edge pixels we use the Anti-aliased Euclidean distance
+   *     transform algorithm and compute approximate edge distances (see
+   *     `compute_edge_distance` and/or the second paper for more).
+   *
+   * (3) Now that we have computed approximate distances for edge pixels we
+   *     use the 8SED algorithm to basically sweep the entire bitmap and
+   *     compute distances for the rest of the pixels.  (Since the algorithm
+   *     is pretty convoluted it is only explained briefly in a comment to
+   *     function `edt8`.  To see the actual algorithm refer to the first
+   *     paper.)
+   *
+   * (4) Finally, compute the sign for each pixel.  This is done in function
+   *     `finalize_sdf`.  The basic idea is that if a pixel's original
+   *     alpha/coverage value is greater than 0.5 then it is 'inside' (and
+   *     'outside' otherwise).
+   *
+   * Pseudo Code:
+   *
+   * ```
+   * b  = source bitmap;
+   * t  = target bitmap;
+   * dm = list of distances; // dimension equal to b
+   *
+   * foreach grid_point (x, y) in b:
+   * {
+   *   if (is_edge(x, y)):
+   *     dm = approximate_edge_distance(b, x, y);
+   *
+   *   // do the 8SED on the distances
+   *   edt8(dm);
+   *
+   *   // determine the signs
+   *   determine_signs(dm):
+   *
+   *   // copy SDF data to the target bitmap
+   *   copy(dm to t);
+   * }
+   *

+     * anti-aliased bitmaps.
+     *
+     * The algorithm is as follows.
+     *
+     * (1) In anti-aliased images, the pixel's alpha value is the coverage
+     *     of the pixel by the outline.  For example, if the alpha value is
+     *     0.5f we can assume that the outline passes through the center of
+     *     the pixel.
+     *
+     * (2) For this reason we can use that alpha value to approximate the real
+     *     distance of the pixel to edge pretty accurately.  A simple
+     *     approximation is `(0.5f - alpha)`, assuming that the outline is
+     *     parallel to the x or y~axis.  However, in this algorithm we use a
+     *     different approximation which is quite accurate even for
+     *     non-axis-aligned edges.
+     *
+     * (3) The only remaining piece of information that we cannot

+   * A brief technical overview of how the SDF rasterizer works
+   * ----------------------------------------------------------
+   *
+   * [Notes]:
+   *   * SDF stands for Signed Distance Field everywhere.
+   *
+   *   * This renderer generates SDF directly from outlines.  There is
+   *     another renderer called 'bsdf', which converts bitmaps to SDF; see
+   *     file `ftbsdf.c` for more.
+   *
+   *   * The basic idea of generating the SDF is taken from Viktor Chlumsky's
+   *     research paper.  The paper explains both single and multi-channel
+   *     SDF, however, this implementation only generates single-channel SDF.

+   *       Fields.  Master's thesis.  Czech Technical University in Prague,
+   *       Faculty of InformationTechnology, 2015.
+   *
+   *     For more information: https://github.com/Chlumsky/msdfgen
+   *
+   * ========================================================================
+   *
+   * Generating SDF from outlines is pretty straightforward.
+   *
+   * (1) We have a set of contours that make the outline of a shape/glyph.
+   *     Each contour comprises of several edges, with three types of edges.
+   *
+   *     * line segments
+   *     * conic Bezier curves
+   *     * cubic Bezier curves
+   *
+   * (2) Apart from the outlines we also have a two-dimensional grid, namely
+   *     the bitmap that is used to represent the final SDF data.
+   *
+   * (3) In order to generate SDF, our task is to find shortest signed
+   *     distance from each grid point to the outline.  The 'signed
+   *     distance' means that if the grid point is filled by any contour
+   *     then its sign is positive, otherwise it is negative.  The pseudo
+   *     code is as follows.
+   *
+   *     ```
+   *     foreach grid_point (x, y):
+   *     {
+   *       int min_dist = INT_MAX;
+   *
+   *       foreach contour in outline:
+   *       {
+   *         foreach edge in contour:
+   *         {
+   *           // get shortest distance from point (x, y) to the edge
+   *           d = get_min_dist(x, y, edge);
+   *
+   *           if (d < min_dist)
+   *             min_dist = d;
+   *         }
+   *
+   *         bitmap[x, y] = min_dist;
+   *       }
+   *     }
+   *     ```
+   *
+   * (4) After running this algorithm the bitmap contains information about
+   *     the shortest distance from each point to the outline of the shape.
+   *     Of course, while this is the most straightforward way of generating
+   *     SDF, we use various optimizations in our implementation.  See the
+   *     `sdf_generate_*' functions in this file for all details.
+   *
+   *     The optimization currently used by default is subdivision; see
+   *     function `sdf_generate_subdivision` for more.
+   *
+   *     Also, to see how we compute the shortest distance from a point to
+   *     each type of edge, check out the `get_min_distance_*' functions.

+   *
+   * @Description:
+   *   At some places on the grid two edges can give opposite directions;
+   *   this happens when the closest point is on one of the endpoint.  In
+   *   that case we need to check the proper sign.
+   *
+   *   This can be visualized by an example:
+   *
+   *   ```
+   *                x
+   *
+   *                   o
+   *                  ^ \
+   *                 /   \
+   *                /     \
+   *           (a) /       \  (b)
+   *              /         \
+   *             /           \
+   *            /             v
+   *   ```
+   *
+   *   Suppose `x` is the point whose shortest distance from an arbitrary
+   *   contour we want to find out.  It is clear that `o` is the nearest
+   *   point on the contour.  Now to determine the sign we do a cross
+   *   product of the shortest distance vector and the edge direction, i.e.,
+   *
+   *   ```
+   *   => sign = cross(x - o, direction(a))
+   *   ```
+   *
+   *   Using the right hand thumb rule we can see that the sign will be
+   *   positive.
+   *
+   *   If we use `b', however, we have
+   *
+   *   ```
+   *   => sign = cross(x - o, direction(b))
+   *   ```
+   *
+   *   In this case the sign will be negative.  To determine the correct
+   *   sign we thus divide the plane in two halves and check which plane the
+   *   point lies in.
+   *
+   *   ```
+   *                   |
+   *                x  |
+   *                   |
+   *                   o
+   *                  ^|\
+   *                 / | \
+   *                /  |  \
+   *           (a) /   |   \  (b)
+   *              /    |    \
+   *             /           \
+   *            /             v
+   *   ```
+   *
+   *   We can see that `x` lies in the plane of `a`, so we take the sign
+   *   determined by `a`.  This test can be easily done by calculating the
+   *   orthogonality and taking the greater one.
+   *
+   *   The orthogonality is simply the sinus of the two vectors (i.e.,
+   *   x - o) and the corresponding direction.  We efficiently pre-compute
+   *   the orthogonality with the corresponding `get_min_distance_*`
+   *   functions.
+   *
+   * @Input:
+   *   sdf1 ::
+   *     First signed distance (can be any of `a` or `b`).
+   *

+   *
+   * @Return:
+   *   The correct signed distance, which is computed by using the above
+   *   algorithm.
+   *
+   * @Note:
+   *   The function does not care about the actual distance, it simply
+   *   returns the signed distance which has a larger cross product.  As a
+   *   consequence, this function should not be used if the two distances
+   *   are fairly apart.  In that case simply use the signed distance with
+   *   a shorter absolute distance.

+     * In order to calculate the shortest distance from a point to

+     * b = end point of the line segment
+     * p = point from which shortest distance is to be calculated
+     * ```
+     *
+     * (1) Write the parametric equation of the line.
+     *
+     *     ```
+     *     point_on_line = a + (b - a) * t   (t is the factor)
+     *     ```
+     *
+     * (2) Find the projection of point `p` on the line.  The projection
+     *     will be perpendicular to the line, which allows us to get the
+     *     solution by making the dot product zero.
+     *
+     *     ```
+     *     (point_on_line - a) . (p - point_on_line) = 0
+     *
+     *                (point_on_line)

+     *                 (p)
+     *     ```
+     *
+     * (3) Simplification of the above equation yields the factor of
+     *     `point_on_line`:
+     *
+     *     ```
+     *     t = ((p - a) . (b - a)) / |b - a|^2
+     *     ```
+     *
+     * (4) We clamp factor `t` between [0.0f, 1.0f] because `point_on_line`
+     *     can be outside of the line segment:
+     *
+     *     ```

+     *     ```
+     *
+     * (5) Finally, the distance we are interested in is

+     * difference from line is that there can be more than one
+     * perpendicular, and we also have to check the endpoints, because the
+     * perpendicular may not be the shortest.
+     *
+     * Let's assume that

+     * p1 = control point
+     * p2 = second endpoint
+     * p  = point from which shortest distance is to be calculated
+     * ```
+     *
+     * (1) The equation of a quadratic Bezier curve can be written as
+     *
+     *     ```
+     *     B(t) = (1 - t)^2 * p0 + 2(1 - t)t * p1 + t^2 * p2
+     *     ```
+     *
+     *     with `t` a factor in the range [0.0f, 1.0f].  This equation can
+     *     be rewritten as
+     *
+     *     ```
+     *     B(t) = t^2 * (p0 - 2p1 + p2) + 2t * (p1 - p0) + p0
+     *     ```

+     *     B = p1 - p0
+     *     ```
+     *
+     *     we have
+     *
+     *     ```
+     *     B(t) = t^2 * A + 2t * B + p0
+     *     ```
+     *
+     * (2) The derivative of the last equation above is
+     *
+     *     ```
+     *     B'(t) = 2 *(tA + B)
+     *     ```
+     *
+     * (3) To find the shortest distance from `p` to `B(t)` we find the
+     *     point on the curve at which the shortest distance vector (i.e.,
+     *     `B(t) - p`) and the direction (i.e., `B'(t)`) make 90 degrees.
+     *     In other words, we make the dot product zero.
+     *
+     *     ```
+     *     (B(t) - p) . (B'(t)) = 0
+     *     (t^2 * A + 2t * B + p0 - p) . (2 * (tA + B)) = 0
+     *     ```
+     *
+     *     After simplifying we get a cubic equation
+     *
+     *     ```
+     *     at^3 + bt^2 + ct + d = 0
+     *     ```
+     *
+     *     with
+     *

+     *     a = A.A
+     *     b = 3A.B
+     *     c = 2B.B + A.p0 - A.p
+     *     d = p0.B - p.B
+     *     ```
+     *
+     * (4) Now the roots of the equation can be computed using 'Cardano's
+     *     Cubic formula'; we clamp the roots in the range [0.0f, 1.0f].

+     * This method uses Newton-Raphson's approximation to find the shortest
+     * distance from a point to a conic curve.  It does not involve solving
+     * any cubic equation, that is why there is no risk of underflow.
+     *
+     * Let's assume that
+     *
+     * ```
+     * p0 = first endpoint
+     * p1 = control point
+     * p3 = second endpoint
+     * p  = point from which shortest distance is to be calculated
+     * ```
+     *
+     * (1) The equation of a quadratic Bezier curve can be written as
+     *
+     *     ```
+     *     B(t) = (1 - t)^2 * p0 + 2(1 - t)t * p1 + t^2 * p2
+     *     ```
+     *
+     *     with `t` the factor in the range [0.0f, 1.0f].  The above
+     *     equation can be rewritten as
+     *
+     *     ```
+     *     B(t) = t^2 * (p0 - 2p1 + p2) + 2t * (p1 - p0) + p0
+     *     ```
+     *
+     *     With
+     *
+     *     ```
+     *     A = p0 - 2p1 + p2
+     *     B = 2 * (p1 - p0)
+     *     ```
+     *
+     *     we have
+     *
+     *     ```
+     *     B(t) = t^2 * A + t * B + p0
+     *     ```
+     *
+     * (2) The derivative of the above equation is
+     *
+     *     ```
+     *     B'(t) = 2t * A + B
+     *     ```
+     *
+     * (3) The second derivative of the above equation is
+     *
+     *     ```
+     *     B''(t) = 2A
+     *     ```
+     *
+     * (4) The equation `P(t)` of the distance from point `p` to the curve
+     *     can be written as
+     *
+     *     ```
+     *     P(t) = t^2 * A + t^2 * B + p0 - p
+     *     ```

+     *     ```
+     *     C = p0 - p
+     *     ```
+     *
+     *     we have
+     *
+     *     ```
+     *     P(t) = t^2 * A + t * B + C
+     *     ```
+     *
+     * (5) Finally, the equation of the angle between `B(t)` and `P(t)` can
+     *     be written as
+     *
+     *     ```
+     *     Q(t) = P(t) . B'(t)
+     *     ```
+     *
+     * (6) Our task is to find a value of `t` such that the above equation
+     *     `Q(t)` becomes zero, that is, the point-to-curve vector makes
+     *     90~degrees with the curve.  We solve this with the Newton-Raphson
+     *     method.
+     *
+     * (7) We first assume an arbitrary value of factor `t`, which we then
+     *     improve.
+     *
+     *     ```
+     *     t := Q(t) / Q'(t)
+     *     ```
+     *
+     *     Putting the value of `Q(t)` from the above equation gives
+     *
+     *     ```
+     *     t := P(t) . B'(t) / derivative(P(t) . B'(t))
+     *     t := P(t) . B'(t) /
+     *            (P'(t) . B'(t) + P(t) . B''(t))
+     *     ```
+     *
+     *     Note that `P'(t)` is the same as `B'(t)` because the constant is
+     *     gone due to the derivative.
+     *
+     * (8) Finally we get the equation to improve the factor as
+     *
+     *     ```
+     *     t := P(t) . B'(t) /
+     *            (B'(t) . B'(t) + P(t) . B''(t))
+     *     ```
+     *
+     * [note]: `B` and `B(t)` are different in the above equations.

+   *   Instead of checking all pixels against all edges, we loop over all
+   *   edges and only check pixels around the control box of the edge; the
+   *   control box is increased by the spread in all directions.  Anything
+   *   outside of the control box that exceeds `spread` doesn't need to be
+   *   computed.
+   *
+   *   Lastly, to determine the sign of unchecked pixels, we do a single
+   *   pass of all rows starting with a '+' sign and flipping when we come
+   *   across a '-' sign and continue.  This also eliminates the possibility
+   *   of overflow because we only check the proximity of the curve.
+   *   Therefore we can use squared distanced safely.

+   *
+   *   spread ::
+   *     This is an essential parameter/property required by the renderer.
+   *     `spread` defines the maximum unsigned value that is present in the
+   *     final SDF output.  For the default value check file
+   *     `ftsdfcommon.h`.
+   *
+   *   flip_sign ::
+   *     By default positive values indicate positions inside of contours,
+   *     i.e., filled by a contour.  If this property is true then that
+   *     output will be the opposite of the default, i.e., negative values
+   *     indicate positions inside of contours.
+   *
+   *   flip_y ::
+   *     Setting this parameter to true maked the output image flipped
+   *     along the y-axis.
+   *
+   *   overlaps ::
+   *     Set this to true to generate SDF for glyphs having overlapping
+   *     contours.  The overlapping support is limited to glyphs that do not
+   *     have self-intersecting contours.  Also, removing overlaps require a
+   *     considerable amount of extra memory; additionally, it will not work
+   *     if generating SDF from bitmap.
+   *
+   * @note:
+   *   All properties are valid for both the 'sdf' and 'bsdf' renderers; the
+   *   exception is `overlaps`, which gets ignored by the 'bsdf' renderer.

+   * @description:
+   *   This struct extends the native renderer struct `FT_RendererRec`.  It
+   *   is basically used to store various parameters required by the
+   *   renderer and some additional parameters that can be used to tweak the
+   *   output of the renderer.
+   *
+   * @fields:
+   *   root ::
+   *     The native rendere struct.
+   *
+   *   spread ::
+   *     This is an essential parameter/property required by the renderer.
+   *     `spread` defines the maximum unsigned value that is present in the
+   *     final SDF output.  For the default value check file
+   *     `ftsdfcommon.h`.
+   *
+   *   flip_sign ::
+   *     By default positive values indicate positions inside of contours,
+   *     i.e., filled by a contour.  If this property is true then that
+   *     output will be the opposite of the default, i.e., negative values
+   *     indicate positions inside of contours.
+   *
+   *   flip_y ::
+   *     Setting this parameter to true makes the output image flipped
+   *     along the y-axis.
+   *
+   *   overlaps ::
+   *     Set this to true to generate SDF for glyphs having overlapping
+   *     contours.  The overlapping support is limited to glyphs that do not
+   *     have self-intersecting contours.  Also, removing overlaps require a
+   *     considerable amount of extra memory; additionally, it will not work
+   *     if generating SDF from bitmap.
+   *
+   * @note:
+   *   All properties except `overlaps` are valid for both the 'sdf' and
+   *   'bsdf' renderers.

+         *
+         *   [OS/2's] sTypoAscender, sTypoDescender and sTypoLineGap fields
+         *   are intended to allow applications to lay out documents in a
+         *   typographically-correct and portable fashion.
+         *
+         * This is somewhat at odds with the decades of backwards
+         * compatibility, operating systems and applications doing whatever
+         * they want, not to mention broken fonts.
+         *
+         * Not all fonts have an OS/2 table; in this case, we take the values
+         * in the horizontal header, although there is nothing stopping the
+         * values from being unreliable. Even with a OS/2 table, certain fonts
+         * set the sTypoAscender, sTypoDescender and sTypoLineGap fields to 0
+         * and instead correctly set usWinAscent and usWinDescent.
+         *
+         * As an example, Arial Narrow is shipped as four files ARIALN.TTF,
+         * ARIALNI.TTF, ARIALNB.TTF and ARIALNBI.TTF. Strangely, all fonts have
+         * the same values in their sTypo* fields, except ARIALNB.ttf which
+         * sets them to 0. All of them have different usWinAscent/Descent
+         * values. The OS/2 table therefore cannot be trusted for computing the
+         * text height reliably.
+         *
+         * As a compromise, do the following:
+         *
+         * 1. If the OS/2 table exists and the fsSelection bit 7 is set
+         *    (USE_TYPO_METRICS), trust the font and use the sTypo* metrics.
+         * 2. Otherwise, use the `hhea' table's metrics.
+         * 3. If they are zero and the OS/2 table exists,
+         *    1. use the OS/2 table's sTypo* metrics if they are non-zero.
+         *    2. Otherwise, use the OS/2 table's usWin* metrics.

+   *
+   * It is based on ideas that I initially found in Raph Levien's

+   * different way, and I don't use sorted vector paths.  Also, it doesn't
+   * use floating point values.
+   *
+   * Bézier segments are flattened by splitting them until their deviation
+   * from straight line becomes much smaller than a pixel.  Therefore, the
+   * pixel coverage by a Bézier curve is calculated approximately.  To
+   * estimate the deviation, we use the distance from the control point
+   * to the conic chord centre or the cubic chord trisection.  These
+   * distances vanish fast after each split.  In the conic case, they vanish
+   * predictably and the number of necessary splits can be calculated.
+   *
+   * This renderer has the following advantages:
+   *
+   * - It doesn't need an intermediate bitmap.  Instead, one can supply a
+   *   callback function that will be called by the renderer to draw gray
+   *   spans on any target surface.  You can thus do direct composition on
+   *   any kind of bitmap, provided that you give the renderer the right

-##  The `column' pattern must contain a group to `unbox' the content of
-##  documentation comment blocks.
-##
-##  Later on, paragraphs are converted to long lines, which simplifies the
-##  regular expressions that act upon the text.

------------
-
-This file contains a target function  for FreeType fuzzing.  It can be
-used   with    libFuzzer   (https://llvm.org/docs/LibFuzzer.html)   or
-potentially any other similar fuzzer.
-
-Usage:
-
-  1. Build  `libfreetype.a' and  `ftfuzzer.cc' using  the most  recent
-     clang compiler with these flags:
-
-       # for fuzzer coverage feedback
-       -fsanitize-coverage=edge,8bit-counters
-       # for bug checking
-       -fsanitize=address,signed-integer-overflow,shift
-
-     You  also need  the header  files from  the `libarchive'  library
-     (https://www.libarchive.org/)  for handling  tar files  (see file
-     `ftmutator.cc' below for more).
-
-  2. Link with `libFuzzer' (it contains `main') and `libarchive'.
-
-  3. Run the fuzzer on some test corpus.
-
-The exact flags and commands may vary.
-
-  https://github.com/google/oss-fuzz/tree/master/projects/freetype2
-
-There is a continuous fuzzing bot that runs ftfuzzer.
-
-  https://oss-fuzz.com
-
-(You need an account  to be able to see coverage  reports and the like
-on oss-fuzz.com.)
-
-Check the bot configuration for the most current settings.

-providing additional information.  The main usage is to load AFM files
-for PostScript Type 1 fonts.
-
-However, libFuzzer currently only supports  mutation of a single input
-file.   For  this  reason,  `ftmutator.cc' contains  a  custom  fuzzer
-mutator that uses an uncompressed tar  file archive as the input.  The
-first file in  such a tarball gets  opened by FreeType as  a font, all
-other files are treated as input for `FT_Attach_Stream'.
-
-Compilation is similar to `ftfuzzer.c'.
-
-
-runinput.cc
------------
-
-To run the target function on a set of input files, this file contains
-a   convenience  `main'   function.   Link   it  with   `ftfuzzer.cc',
-`libfreetype.a', and `libarchive' and run like
-
-  ./a.out my_tests_inputs/*

+/* vms_shorten_symbol
+ * 
+ * This program provides shortening of long symbols (> 31 characters) using the
+ * same mechanism as the OpenVMS C compiler.  The basic procedure is to compute
+ * an AUTODIN II checksum of the entire symbol, encode the checksum in base32,
+ * and glue together a shortened symbol from the first 23 characters of the 
+ * original symbol plus the encoded checksum appended.  The output format is
+ * the same used in the name mangler database, stored by default in 
+ * [.CXX_REPOSITORY]CXX$DEMANGLER_DB.
+ *
+ * To obtain the same result as CC/NAMES=SHORTENED, run like so:
+ * 
+ * $ mcr []vms_shorten_symbol "Please_forgive_this_absurdly_long_symbol_name"
+ * PLEASE_FORGIVE_THIS_ABS1ARO4QU$Please_forgive_this_absurdly_long_symbol_name
+ *
+ * To obtain the same result as CC/NAMES=(SHORTENED,AS_IS), pass a non-zero
+ * value as the second argument, like so:
+ *
+ * $ mcr []vms_shorten_symbol "Please_forgive_this_absurdly_long_symbol_name" 1
