+base::MRUCache is a few collections of most-recently-used caching structures.
+base::SHA1 is a secure hashing algorithm.
+
+To update the checkout, simply overwrite the folder with Chromium's latest, apply
+the appropriate namespace, and make sure the paths are correct (anglebase/ instead of
+base/), and update the header guards and macros.
+
+Modifications:
+
+- the file scope is now anglebase/ from base/ to prevent include conflicts.
+- anglebase/logging.h defines (D)CHECK to be ASSERT to be compatible with ANGLE.
+- the headers use namespace angle::base instead of base:: to avoid ODR
+  violations when ANGLE code is mixed with Chromium code.
+- header guards and macros are changed from BASE to ANGLEBASE to prevent conflicts.

+// The following helper template addresses a corner case in range checks for

+//   1. Integral maximum is always one less than a power of two, so it must be
+//      truncated to fit the mantissa of the floating point. The direction of
+//      rounding is implementation defined, but by default it's always IEEE
+//      floats, which round to nearest and thus result in a value of larger
+//      magnitude than the integral value.
+//      Example: float f = UINT_MAX; // f is 4294967296f but UINT_MAX
+//                                   // is 4294967295u.
+//   2. If the floating point value is equal to the promoted integral maximum
+//      value, a range check will erroneously pass.
+//      Example: (4294967296f <= 4294967295u) // This is true due to a precision
+//                                            // loss in rounding up to float.
+//   3. When the floating point value is then converted to an integral, the
+//      resulting value is out of range for the target integral type and
+//      thus is implementation defined.
+//      Example: unsigned u = (float)INT_MAX; // u will typically overflow to 0.
+// To fix this bug we manually truncate the maximum value when the destination
+// type is an integral of larger precision than the source floating-point type,
+// such that the resulting maximum is represented exactly as a floating point.

+// CheckedNumeric implements all the logic and operators for detecting integer
+// boundary conditions such as overflow, underflow, and invalid conversions.
+// The CheckedNumeric type implicitly converts from floating point and integer
+// data types, and contains overloads for basic arithmetic operations (i.e.: +,
+// -, *, /, %).
+//
+// The following methods convert from CheckedNumeric to standard numeric values:
+// IsValid() - Returns true if the underlying numeric value is valid (i.e. has
+//             has not wrapped and is not the result of an invalid conversion).
+// ValueOrDie() - Returns the underlying value. If the state is not valid this
+//                call will crash on a CHECK.
+// ValueOrDefault() - Returns the current value, or the supplied default if the
+//                    state is not valid.
+// ValueFloating() - Returns the underlying floating point value (valid only
+//                   only for floating point CheckedNumeric types).
+//
+// Bitwise operations are explicitly not supported, because correct
+// handling of some cases (e.g. sign manipulation) is ambiguous. Comparison
+// operations are explicitly not supported because they could result in a crash
+// on a CHECK condition. You should use patterns like the following for these
+// operations:
+// Bitwise operation:
+//     CheckedNumeric<int> checked_int = untrusted_input_value;
+//     int x = checked_int.ValueOrDefault(0) | kFlagValues;
+// Comparison:
+//   CheckedNumeric<size_t> checked_size = untrusted_input_value;

+ * MurmurHash3 was written by Austin Appleby, and is placed in the public

+ *
+ * This implementation was written by Shane Day, and is also public domain.
+ *
+ * This is a portable ANSI C implementation of MurmurHash3_x86_32 (Murmur3A)
+ * with support for progressive processing.

+
+/*-----------------------------------------------------------------------------
+ 
+If you want to understand the MurmurHash algorithm you would be much better
+off reading the original source. Just point your browser at:
+http://code.google.com/p/smhasher/source/browse/trunk/MurmurHash3.cpp
+
+
+What this version provides?
+
+1. Progressive data feeding. Useful when the entire payload to be hashed
+does not fit in memory or when the data is streamed through the application.
+Also useful when hashing a number of strings with a common prefix. A partial
+hash of a prefix string can be generated and reused for each suffix string.
+
+2. Portability. Plain old C so that it should compile on any old compiler.
+Both CPU endian and access-alignment neutral, but avoiding inefficient code
+when possible depending on CPU capabilities.
+
+3. Drop in. I personally like nice self contained public domain code, making it
+easy to pilfer without loads of refactoring to work properly in the existing
+application code & makefile structure and mucking around with licence files.
+Just copy PMurHash.h and PMurHash.c and you're ready to go.
+
+
+How does it work?
+
+We can only process entire 32 bit chunks of input, except for the very end
+that may be shorter. So along with the partial hash we need to give back to
+the caller a carry containing up to 3 bytes that we were unable to process.
+This carry also needs to record the number of bytes the carry holds. I use
+the low 2 bits as a count (0..3) and the carry bytes are shifted into the
+high byte in stream order.
+
+To handle endianess I simply use a macro that reads a uint32_t and define
+that macro to be a direct read on little endian machines, a read and swap
+on big endian machines, or a byte-by-byte read if the endianess is unknown.

+//     The root problem is that if the HLSL compiler is applying aliasing information even on
+//     incomplete simulations (in this case, a single pass). The bug is triggered by an assignment
+//     that comes from a series of assignments, possibly with swizzled or ternary operators with
+//     known conditionals, where the source is before the loop.
+//     So, a workaround is to add a +0 term to variables the first time they are assigned to in
+//     an inner loop (if they are declared in an outside scope, otherwise there is no need).
+//     This will break the aliasing chain.
+
+// For simplicity here we add a +0 to any assignment that is in at least two nested loops. Because
+// the bug only shows up with swizzles, and ternary assignment, whole array or whole structure
+// assignment don't need a workaround.

+ * XNVCTRLQueryValidAttributeValues() and/or
+ * XNVCTRLQueryValidTargetAttributeValues()
+ *
+ * Key to Integer Attribute "Permissions":
+ *
+ * R: The attribute is readable (in general, all attributes will be
+ *    readable)
+ *
+ * W: The attribute is writable (attributes may not be writable for
+ *    various reasons: they represent static system information, they
+ *    can only be changed by changing an XF86Config option, etc).
+ *
+ * D: The attribute requires the display mask argument.  The
+ *    attributes NV_CTRL_CONNECTED_DISPLAYS and NV_CTRL_ENABLED_DISPLAYS
+ *    will be a bitmask of what display devices are connected and what
+ *    display devices are enabled for use in X, respectively.  Each bit
+ *    in the bitmask represents a display device; it is these bits which
+ *    should be used as the display_mask when dealing with attributes
+ *    designated with "D" below.  For attributes that do not require the
+ *    display mask, the argument is ignored.
+ *
+ *    Alternatively, NV-CONTROL versions 1.27 and greater allow these
+ *    attributes to be accessed via display target types, in which case
+ *    the display_mask is ignored.

+ * G: The attribute may be queried using an NV_CTRL_TARGET_TYPE_GPU
+ *    target type via XNVCTRLQueryTargetAttribute().
+ *
+ * F: The attribute may be queried using an NV_CTRL_TARGET_TYPE_FRAMELOCK
+ *    target type via XNVCTRLQueryTargetAttribute().
+ *
+ * X: When Xinerama is enabled, this attribute is kept consistent across
+ *    all Physical X Screens;  assignment of this attribute will be
+ *    broadcast by the NVIDIA X Driver to all X Screens.
+ *
+ * V: The attribute may be queried using an NV_CTRL_TARGET_TYPE_VCSC
+ *    target type via XNVCTRLQueryTargetAttribute().
+ *
+ * I: The attribute may be queried using an NV_CTRL_TARGET_TYPE_GVI target type
+ *    via XNVCTRLQueryTargetAttribute().
+ *
+ * Q: The attribute is a 64-bit integer attribute;  use the 64-bit versions

+ * The NV_CTRL_GVO_* integer attributes are used to configure GVO

+ *
+ * The following is a typical usage pattern for the GVO attributes:
+ *
+ * - query NV_CTRL_GVO_SUPPORTED to determine if the X screen supports GV0.
+ *
+ * - specify NV_CTRL_GVO_SYNC_MODE (one of FREE_RUNNING, GENLOCK, or
+ * FRAMELOCK); if you specify GENLOCK or FRAMELOCK, you should also
+ * specify NV_CTRL_GVO_SYNC_SOURCE.
+ *
+ * - Use NV_CTRL_GVO_COMPOSITE_SYNC_INPUT_DETECTED and
+ * NV_CTRL_GVO_SDI_SYNC_INPUT_DETECTED to detect what input syncs are
+ * present.
+ *
+ * (If no analog sync is detected but it is known that a valid
+ * bi-level or tri-level sync is connected set
+ * NV_CTRL_GVO_COMPOSITE_SYNC_INPUT_DETECT_MODE appropriately and
+ * retest with NV_CTRL_GVO_COMPOSITE_SYNC_INPUT_DETECTED).
+ *
+ * - if syncing to input sync, query the
+ * NV_CTRL_GVIO_DETECTED_VIDEO_FORMAT attribute; note that Input video
+ * format can only be queried after SYNC_SOURCE is specified.
+ *
+ * - specify the NV_CTRL_GVIO_REQUESTED_VIDEO_FORMAT
+ *
+ * - specify the NV_CTRL_GVO_DATA_FORMAT
+ *
+ * - specify any custom Color Space Conversion (CSC) matrix, offset,
+ * and scale with XNVCTRLSetGvoColorConversion().
+ *
+ * - if using the GLX_NV_video_out extension to display one or more
+ * pbuffers, call glXGetVideoDeviceNV() to lock the GVO output for use
+ * by the GLX client; then bind the pbuffer(s) to the GVO output with
+ * glXBindVideoImageNV() and send pbuffers to the GVO output with
+ * glXSendPbufferToVideoNV(); see the GLX_NV_video_out spec for more
+ * details.
+ *
+ * - if using the GLX_NV_present_video extension, call
+ * glXBindVideoDeviceNV() to bind the GVO video device to current
+ * OpenGL context.
+ *
+ * Note that setting most GVO attributes only causes the value to be
+ * cached in the X server.  The values will be flushed to the hardware
+ * either when the next MetaMode is set that uses the GVO display
+ * device, or when a GLX pbuffer is bound to the GVO output (with
+ * glXBindVideoImageNV()).
+ *
+ * Note that GLX_NV_video_out/GLX_NV_present_video and X screen use
+ * are mutually exclusive.  If a MetaMode is currently using the GVO
+ * device, then glXGetVideoDeviceNV and glXBindVideoImageNV() will
+ * fail.  Similarly, if a GLX client has locked the GVO output (via
+ * glXGetVideoDeviceNV or glXBindVideoImageNV), then setting a

+ *
+ * NV-CONTROL Protocol Version History
+ *
+ * 1.0 - 1.5   NVIDIA Internal development versions
+ * 1.6         Initial public version
+ * 1.7         Added QueryBinaryData request
+ * 1.8         Added TargetTypes
+ * 1.9         Added QueryTargetCount request
+ * 1.10        Fixed target type/id byte ordering for compatibility with
+ *             pre-1.8 NV-CONTROL clients
+ * 1.11        NVIDIA Internal development version
+ * 1.12        Added StringOperation request
+ * 1.13        NVIDIA Internal development version
+ * 1.14        Fixed an NV_CTRL_BINARY_DATA_MODELINES double scan modeline
+ *             reporting bug (vsyncstart, vsyncend, and vtotal were incorrectly
+ *             doubled)
+ * 1.15        Added AVAILABILITY_TARGET_ATTRIBUTE_CHANGED_EVENT
+ * 1.16        Added TARGET_STRING_ATTRIBUTE_CHANGED_EVENT
+ * 1.17        Added TARGET_BINARY_ATTRIBUTE_CHANGED_EVENT
+ * 1.18        Updated QueryTargetCount to return a count of 0, rather than
+ *             BadMatch, if an unknown TargetType is specified
+ * 1.19        Added TargetType support for SetAttributeAndGetStatus and
+ *             SetStringAttribute requests
+ * 1.20        Added COOLER TargetType
+ * 1.21        Added initial 64-bit integer attribute support (read-only)
+ * 1.22        Added X_nvCtrlQueryValidStringAttributeValues to check
+ *             string attribute permissions.
+ * 1.23        Added SENSOR TargetType
+ * 1.24        Fixed a bug where SLI_MOSAIC_MODE_AVAILABLE attribute would
+ *             report false positives via the GPU and X screen target types
+ * 1.25        Added 3D_VISION_PRO_TRANSCEIVER TargetType
+ * 1.26        Added XNVCTRLQueryXXXAttributePermissions.
+ * 1.27        Added DISPLAY TargetType
+ * 1.28        Added NV_CTRL_CURRENT_METAMODE_ID: clients should use this
+ *             attribute to switch MetaModes, rather than pass the MetaMode ID
+ *             through the RRSetScreenConfig protocol request.

+CHANGES BETWEEN 2.9 and 2.9.1
+
+  I. IMPORTANT BUG FIXES
+
+    - Type  1  fonts  containing   flex  features  were  not  rendered
+      correctly (bug introduced in version 2.9).
+
+    - CVE-2018-6942: Older  FreeType versions  can crash  with certain
+      malformed variation fonts.
+
+        http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-6942
+
+
+  II. MISCELLANEOUS
+
+    - Bug fix: Multiple calls to `FT_Get_MM_Var' returned garbage.
+
+    - The base  extensions `ftlcdfil' and  `ftfntfmt' are now  part of
+      the  base  module  (and  thus no  longer  configurable  in  file
+      `modules.cfg').
+
+    - Emboldening of bitmaps didn't work correctly sometimes,  showing
+      various artifacts (bug introduced in version 2.8.1).
+
+    - Use  of  the `freetype-config'  script  to  get compilation  and
+      linking  options   is  deprecated   since  it   doesn't  support
+      cross-compiling, among other  deficiencies.  Instead, you should
+      use the `pkg-config' interface.
+
+      The `configure'  script no longer installs  `freetype-config' by
+      default.  For  backwards compatibility,  a new  configure option
+      `--enable-freetype-config'   is  provided   that  reverts   this
+      decision.
+
+    - The auto-hinter script ranges have  been updated for Unicode 11.
+      No support  for new scripts  have been added, however,  with the
+      exception of Georgian Mtavruli.
+
+    - Support for cmake has been improved.
+
+    - The next  release will  remove support for  Position Independent
+      Code  as  needed  by  systems that  prohibit  automatic  address
+      fixups, such  as BREW.  [Compilation with  modern compilers that
+      use flags like `-fPIC' or `-fPIE' is not affected.]
+
+
+======================================================================
+
+CHANGES BETWEEN 2.8.1 and 2.9
+
+  I. IMPORTANT BUG FIXES
+
+    - Advance width values of variation fonts were often wrong.
+
+    - More fixes for variation font support; you should update to this
+      version if you want to support them.
+
+
+  II. IMPORTANT CHANGES
+
+    - As a GSoC project, Ewald Hew extended the new (Adobe) CFF engine
+      to  handle  Type  1  fonts  also,  thus  greatly  improving  the
+      rendering of  this format.   This is the  new default.   The old
+      engine   is  still   available   if   the  configuration   macro
+      `T1_CONFIG_OPTION_OLD_ENGINE'    gets    defined;   using    the
+      `hinting-engine' property  of the `type1' driver  module you can
+      then switch between the two engines.
+
+    - A new function,  `FT_Set_Named_Instance', can be used  to set or
+      change the current named instance.
+
+    - Starting  with   this  FreeType  version,   resetting  variation
+      coordinates  will   return  to  the  currently   selected  named
+      instance.  Previously, FreeType returned to the base font (i.e.,
+      no instance set).
+
+
+  III. MISCELLANEOUS
+
+    - The `face_flags' field of the `FT_Face' structure has a new bit,
+      `FT_FACE_FLAG_VARIATION', which  is set if a  variation font has
+      been      altered      with      `FT_Set_MM_Design_Coordinates',
+      `FT_Set_Var_Design_Coordinates',                              or
+      `FT_Set_Var_Blend_Coordinates'.
+
+    - If  the  current  face  is  a  named  instance,  the  new  macro
+      `FT_IS_NAMED_INSTANCE' returns true.
+
+    - `FT_IS_VARIATION' is  a new macro  that returns true  whenever a
+      face object has  been altered by `FT_Set_MM_Design_Coordinates',
+      `FT_Set_Var_Design_Coordinates',                              or
+      `FT_Set_Var_Blend_Coordinates'.
+
+    - Changing  the  design  coordinates  of  a  variation  font  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).
+
+    - Special PostScript  names for named instances  are only returned
+      if the  named instance is set  with `FT_Set_Named_Instance' (and
+      the font  has corresponding  entries in  its `fvar'  table).  If
+      `FT_IS_VARIATION'  returns  true,  the  algorithmically  derived
+      PostScript name is provided, not  looking up special entries for
+      named instances.
+
+    - A new function  `FT_Done_MM_Var' is provided to  free the memory
+      returned in a call to `FT_Get_MM_Var'.
+
+    - On  platforms  using  the   `configure'  script,  the  installed
+      `ftoption.h' file  now correctly reflects  configuration options
+      like `--with-harfbuzz'.
+
+    - Better  support to  build FreeType  as  a DLL  on Windows  using
+      Visual C.
+
+    - All data specific to driver modules is now collected in a single
+      file,      `FT_DRIVER_H'.      Consequently,      the     macros
+      `FT_AUTOHINTER_H',   `FT_CFF_DRIVER_H',  `FT_TRUETYPE_DRIVER_H',
+      and `FT_PCF_DRIVER_H' still work but are deprecated.
+
+    - Some fuzzer fixes to better reject malformed fonts.
+
+    - The `ftbench' demo program has a new test for opening a new face
+      and loading some glyphs.
+
+    - The `ftbench' demo program has a  new option `-j' to specify the
+      last glyph index to be used in the tests.
+
+    - The  `ftgrid' demo  program has  a new  option `-n'  to suppress
+      display of named instances of variation fonts.
+
+    - The `ttdebug' demo program can now  show a stack trace (key `K')
+      and switch  between hexadecimal and decimal  display of integers
+      (key `I').
+
+
+======================================================================
+
+CHANGES BETWEEN 2.8 and 2.8.1
+
+  I. IMPORTANT BUG FIXES
+
+    - B/W  hinting   of  TrueType   fonts  didn't  work   properly  if
+      interpreter version 38 or 40 was selected.
+
+    - Some severe  problems within the handling  of TrueType Variation
+      Fonts were found and fixed.
+
+    - Function `FT_Set_Var_Design_Coordinates' didn't correctly handle
+      the case with less input coordinates than axes.
+
+
+  II. IMPORTANT CHANGES
+
+    - By  default,  FreeType  now offers  high  quality  LCD-optimized
+      output without  resorting to ClearType techniques  of resolution
+      tripling and  filtering.  In  this method, called  Harmony, each
+      color channel  is generated separately after  shifting the glyph
+      outline, capitalizing  on the fact  that the color grids  on LCD
+      panels  are shifted  by  a third  of a  pixel.   This output  is
+      indistinguishable from ClearType with a light 3-tap filter.
+
+
+  III. MISCELLANEOUS
+
+    - Using the  new function `FT_Get_Var_Axis_Flags',  an application
+      can access the `flags' field  of a variation axis (introduced in
+      OpenType version 1.8.2)
+
+    - More sanity checks.
+
+    - The  internal representation  of buffers  for LCD  rendering has
+      changed (to be more precise, the amount of padding gets computed
+      differently).  Applications  that use  the FreeType API  are not
+      affected.
+
+    - To  reset all  design axis  values of  a variation  font to  its
+      default values you can now say
+
+        error = FT_Set_Var_Design_Coordinates( face, 0, NULL );
+
+      This  also works  with functions  `FT_Set_MM_Design_Coordinates'
+      and `FT_Set_MM_Blend_Coordinates'.
+
+    - FreeType  now synthesizes  a  missing Unicode  cmap for  (older)
+      TrueType fonts also if glyph names are available.
+
+    - FreeType  has  improved  handling   of  BDF  fonts  without  the
+      `POINT_SIZE', `RESOLUTION_X', or  `RESOLUTION_Y' properties; the
+      library now  uses the values of  the `SIZE' keyword if  they are
+      missing.   Previously,   `SIZE'  was  completely   ignored,  and
+      FreeType used heuristic values instead.
+
+    - Multiple calls to `FT_Bitmap_Convert' do work now as advertised.
+      Previously,  they failed with an assertion error if there was an
+      empty bitmap between non-empty ones.
+
+    - The warping option  has moved  from `light'  to `normal' hinting
+      where  it replaces  the original hinting algorithm.  The `light'
+      mode is now always void of any hinting in x-direction.
+
+    - 16bit  compiler  support is  now  officially  ended.  We  didn't
+      provide any maintenance  since many years,  and given that there
+      were no error  or problem reports either it seems  that it is no
+      longer needed.
+
+    - The `ftgrid'  demo program  can now toggle  the display  of grid
+      lines with the `G' key.
+
+    - The `ftgrid' demo  program can toggle a different  set of colors
+      (suitable to color-blind people) with the `C' key.
+
+    - The `ftgrid'  demo program  now supports  the `-e'  command line
+      option to select a cmap.
+
+    - The `ftdump' demo program has a  new command line option `-t' to
+      output the SFNT table list.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.7.1 and 2.8
+
+  I. IMPORTANT CHANGES
+
+    - Support for OpenType Variation Fonts is now complete.   The last
+      missing part was handling the `VVAR' and `MVAR' tables, which is
+      available with this release.
+
+    - A new  function `FT_Face_Properties' allows the  control of some
+      module  and   library  properties  per  font.    Currently,  the
+      following properties can be  handled: stem darkening, LCD filter
+      weights, and the random seed for the `random' CFF operator.
+
+    - The PCF change to show more `colourful' family names (introduced
+      in version 2.7.1) was too radical; it can now be configured with
+      PCF_CONFIG_OPTION_LONG_FAMILY_NAMES   at   compile   time.    If
+      activated, it can  be switched off at run time  with the new pcf
+      property  `no-long-family-names'.  If  the `FREETYPE_PROPERTIES'
+      environment variable is available, you can say
+
+        FREETYPE_PROPERTIES=pcf:no-long-family-names=1
+
+    - Support  for  the  following  scripts  has  been  added  to  the
+      auto-hinter.
+
+        Adlam, Avestan, Bamum, Buhid, Carian, Chakma, Coptic, Cypriot,
+        Deseret, Glagolitic, Gothic, Kayah, Lisu, N'Ko, Ol Chiki, Old
+        Turkic, Osage, Osmanya, Saurashtra, Shavian, Sundanese, Tai
+        Viet, Tifinagh, Unified Canadian Syllabics, Vai
+
+
+  II. IMPORTANT BUG FIXES
+
+    - `Light' auto-hinting  mode no  longer uses TrueType  metrics for
+      TrueType  fonts.   This bug  was  introduced  in version  2.4.6,
+      causing   horizontal  scaling   also.    Almost  all   GNU/Linux
+      distributions (with Fedora as  a notable exception) disabled the
+      corresponding patch for good reasons; chances are thus high that
+      you won't notice a difference.
+
+      If  optical backward  compatibility for  legacy applications  is
+      necessary, you might enable the AF_CONFIG_OPTION_TT_SIZE_METRICS
+      configuration option.   However, it  is strongly  recommended to
+      avoid that, adjusting font sizes instead.
+
+    - Global size  metrics values  in the  `FT_Size_Metrics' structure
+      can be  different for TrueType  fonts.  Reason is that  in older
+      FreeType  versions  the  metrics  were  rounded  differently  to
+      integer pixels compared  to all other font  formats, yielding an
+      inconsistent behaviour if you used non-native hinting.  Starting
+      with this  version, global size  metrics for TrueType  fonts are
+      handled the same as other  font formats: `ascender' gets rounded
+      up,  `descender'  gets  rounded  down,  `height'  gets  normally
+      rounded, and `max_advance' gets normally rounded, too.
+
+      If you need more precise values of (global) ascender, descender,
+      height, or  `max_advance', please take the  corresponding values
+      from the `FT_Face' structure and scale them manually.
+
+    - If a TrueType font gets loaded with FT_LOAD_NO_HINTING, FreeType
+      now scales  the font linearly  again (bug introduced  in version
+      2.4.6).
+
+    - CVE-2017-8105,  CVE-2017-8287:  Older   FreeType  versions  have
+      out-of-bounds  writes  caused  by  heap-based  buffer  overflows
+      related to Type 1 fonts.
+
+        https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8105
+        https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-8287
+
+
+  III. MISCELLANEOUS
+
+    - A  new function  `FT_Set_Default_Properties' has  been added  to
+      parse    the    `FREETYPE_PROPERTIES'    environment    variable
+      (previously, it  was internal only).   `FT_Init_FreeType' always
+      call this  function, but  `FT_New_Library' does not  (similar to
+      `FT_Add_Default_Modules').
+
+    - To be in sync with OpenType version 1.7 and newer, macros
+
+        FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY,
+        FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY,
+        TT_NAME_ID_PREFERRED_FAMILY
+        TT_NAME_ID_PREFERRED_SUBFAMILY
+
+      are renamed to
+
+        FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY,
+        FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY,
+        TT_NAME_ID_TYPOGRAPHIC_FAMILY
+        TT_NAME_ID_TYPOGRAPHIC_SUBFAMILY
+
+      The old macro names are deprecated (but still available).
+
+    - Support for SFNT `name' tables has been improved.
+
+      . Format  1 `name' tables  are now supported.  Use  new function
+        `FT_Get_Sfnt_LangTag' to access associated language tags.
+
+      . Language, encoding, and name IDs have been updated to OpenType
+        version 1.8.1.
+
+    - The new CFF  engine now handles the `random'  operator.  All CFF
+      opcodes are now supported.
+
+    - The CFF module  has a new property `random-seed'  to control the
+      pseudo-random number generation for the `random' operator.
+
+    - The `freetype-config' script is now a wrapper of `pkg-config' if
+      this program is available in the path.
+
+    - FT_LOAD_TARGET_LCD  is now  a  variant of  FT_LOAD_TARGET_LIGHT;
+      this should provide better rendering results.
+
+    - A mode to display  light auto-hinting with  subpixel positioning
+      has been added to `ftdiff'.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.7 and 2.7.1
+
+  I. IMPORTANT CHANGES
+
+    - Support for the new CFF2 font format as introduced with OpenType
+      1.8 has been contributed by Dave Arnolds from Adobe.
+
+    - Preliminary support for variation fonts as specified in OpenType
+      1.8 (in addition to the  already existing support for Adobe's MM
+      and Apple's  GX formats).  Dave Arnolds  contributed handling of
+      advance  width change  variation;  more will  come  in the  next
+      version.
+
+
+  II. IMPORTANT BUG FIXES
+
+    - Handling of  raw CID fonts was partially  broken (bug introduced
+      in 2.6.4).
+
+    - CVE-2016-10328:  Older  FreeType versions had  an  out-of-bounds
+      write caused by a heap-based  buffer overflow related to the CFF
+      fonts.
+
+        https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-10328
+
+
+  III. MISCELLANEOUS
+
+    - Some limits for TrueType  bytecode execution have been tightened
+      to  speed   up  FreeType's  handling  of   malformed  fonts,  in
+      particular to quickly abort endless loops.
+
+      - The  number of  twilight points  can no  longer be  set to  an
+        arbitrarily large value.
+
+      - The total number of jump  opcode instructions (like JMPR) with
+        negative arguments  is dynamically restricted; the  same holds
+        for the total number of iterations in LOOPCALL opcodes.
+
+      The dynamic limits are based on  the number of points in a glyph
+      and the number of CVT entries.  Please report if you encounter a
+      font where the selected values are not adequate.
+
+    - PCF family names are made more `colourful'; they now include the
+      foundry  and information  whether they contain  wide characters.
+      For example,  you no longer get `Fixed' but  rather `Sony Fixed'
+      or `Misc Fixed Wide'.
+
+    - A new  function `FT_Get_Var_Blend_Coordinates'  (with its  alias
+      name  `FT_Get_MM_Blend_Coordinates') to retrieve the  normalized
+      blend  coordinates of the currently  selected variation instance
+      has been added to the Multiple Masters interface.
+
+    - A new  function `FT_Get_Var_Design_Coordinates' to  retrieve the
+      design coordinates of the  currently selected variation instance
+      has been added to the Multiple Masters interface.
+
+    - A new load flag `FT_LOAD_BITMAP_METRICS_ONLY' to retrieve bitmap
+      information without loading the (embedded) bitmap itself.
+
+    - Retrieving   advance   widths   from   bitmap   strikes   (using
+      `FT_Get_Advance' and `FT_Get_Advances') have been sped up.
+
+    - The  usual round  of  fuzzer fixes  to  better reject  malformed
+      fonts.
+
+    - The `ftmulti' demo program can now switch engines with key `H'.
+
+    - The  `ftstring'  demo  program   can  now  show  some  built-in,
+      non-latin sample strings (to be selected with the TAB key).
+
+    - The  `ftview'  demo program  can  now  switch between  a  font's
+      charmaps using the TAB key.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.5 and 2.7
+
+  I. IMPORTANT CHANGES
+
+    - As announced earlier, the 2.7.x series now uses the new subpixel
+      hinting  mode as  the  default, emulating  a  modern version  of
+      ClearType.
+
+      This change inevitably leads to different rendering results, and
+      you   might   change   the   `TT_CONFIG_OPTION_SUBPIXEL_HINTING'
+      configuration option to  adapt it to your taste (or  use the new
+      `FREETYPE_PROPERTIES'    environment    variable).    See    the
+      corresponding entry  below for  version 2.6.4, which  gives more
+      information.
+
+    - A new option  `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' has been
+      introduced.   If  set (which  is  the  default), an  environment
+      variable  `FREETYPE_PROPERTIES' can  be used  to control  driver
+      properties.  Example:
+
+        FREETYPE_PROPERTIES=truetype:interpreter-version=35 \
+                            cff:no-stem-darkening=1 \
+                            autofitter:warping=1
+
+      This allows to select, say, the subpixel hinting mode at runtime
+      for a given application.  See file `ftoption.h' for more.
+
+
+  II. IMPORTANT BUG FIXES
+
+    - After  loading a  named instance  of  a GX  variation font,  the
+      `face_index'  value  in  the returned  `FT_Face'  structure  now
+      correctly holds the named instance  index in the upper 16bits as
+      documented.
+
+
+  III. MISCELLANEOUS
+
+    - A new macro `FT_IS_NAMED_INSTANCE' to  test whether a given face
+      is a named instance.
+
+    - More fixes to GX font handling.
+
+    - Apple's   `GETVARIATION'  bytecode   operator  (needed   for  GX
+      variation font support) has been implemented.
+
+    - Another round  of fuzzer fixes,  mainly to reject  invalid fonts
+      faster.
+
+    - Handling of raw CID fonts  was broken (bug introduced in version
+      2.6.4).
+
+    - The smooth rasterizer has been streamlined  to make it faster by
+      approx. 20%.
+
+    - The `ftgrid'  demo program now  understands command  line option
+      `-d' to give start-up design coordinates.
+
+    - The `ftdump' demo program has  a new command line option `-p' to
+      dump TrueType bytecode instructions.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.4 and 2.6.5
+
+  I. IMPORTANT BUG FIXES
+
+    - Compilation works again  on Mac OS X (bug introduced  in version
+      2.6.4).
+
+
+  II. IMPORTANT CHANGES
+
+    - The new  subpixel hinting  mode is now  disabled by  default; it
+      will  be enabled  by default  in the  forthcoming 2.7.x  series.
+      Main reason for reverting this feature is the principle of least
+      surprise: a  sudden change in  appearance of all fonts  (even if
+      the rendering improves  for almost all recent  fonts) should not
+      be expected in a new micro version of a series.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.3 and 2.6.4
+
+  I. IMPORTANT CHANGES
+
+    - A new  subpixel hinting  mode has  been contributed  by Nikolaus
+      Waxweiler, which is now the  default rendering mode for TrueType
+      fonts.  It implements  (almost everything of) version  40 of the
+      bytecode engine.
+
+      The existing code  base in FreeType (the  `Infinality code') was
+      stripped to the bare minimum  and all configurability removed in
+      the  name  of speed  and  simplicity.   The configurability  was
+      mainly aimed  at legacy  fonts like Arial,  Times New  Roman, or
+      Courier.  [Legacy fonts are fonts  that modify vertical stems to
+      achieve clean black-and-white bitmaps.]  The new mode focuses on
+      applying a minimal set of rules to all fonts indiscriminately so
+      that modern and web fonts  render well while legacy fonts render
+      okay.
+
+      Activation  of the  subpixel hinting  support can  be controlled
+      with   the   `TT_CONFIG_OPTION_SUBPIXEL_HINTING'   configuration
+      option  at compile  time: If  set to  value 1,  you get  the old
+      Infinality  mode  (which  was  never  the  default  due  to  its
+      slowness).  Value 2 activates the new subpixel hinting mode, and
+      value 3 activates both.  The default is value 2.
+
+      At run time,  you can select the subpixel hinting  mode with the
+      `interpreter-version'  property (provided  you have  compiled in
+      the corresponding hinting mode); see `ftttdrv.h' for more.
+
+    - Support  for  the  following  scripts  has  been  added  to  the
+      auto-hinter.
+
+        Armenian, Cherokee, Ethiopic, Georgian, Gujarati, Gurmukhi,
+        Malayalam, Sinhala, Tamil
+
+
+  II. MISCELLANEOUS
+
+    - Type 42 fonts as created by LilyPond are now supported.
+
+    - Minor rendering improvements in the auto-hinter.
+
+    - For experimental  reasons, the old  CFF engine now  supports all
+      CFF operators except `random', including the deprecated Multiple
+      Masters  instructions.  This  allows the  display of  fonts like
+      `ITCGaramondMM-It.otf' (without font variations, though).
+
+    - Another round of fixes to improve handling of invalid fonts.
+
+    - The `ftgrid' demo program now displays the rendered pixels also;
+      this can be switched off with the `b' key.  Selection of various
+      LCD filtering modes can be done with the `L' key.
+
+    - The demo programs  have been extended to allow  selection of all
+      available TrueType bytecode engines.
+
+    - A very early beta version of a new, Qt based demo program called
+      `ftinspect'  is  part  of  the   source  code  bundle;  it  will
+      eventually supersede  the other  demo programs.   Currently, you
+      have to compile  it manually with `qmake; make';  note that many
+      features are still missing.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.2 and 2.6.3
+
+  I. IMPORTANT CHANGES
+
+    - Khmer,  Myanmar, Bengali,  and Kannada  script support  has been
+      added to the auto-hinter.
+
+
+  II. MISCELLANEOUS
+
+    - Better  support of  Indic  scripts like  Devanagari  by using  a
+      top-to-bottom hinting flow.
+
+    - All  FreeType macros  starting  with two  underscores have  been
+      renamed to  avoid a violation of  both the C and  C++ standards.
+      Example: Header  macros of the  form `__FOO_H__' are  now called
+      `FOO_H_'.  In most cases,  this should be completely transparent
+      to the user.   The exception to this  is `__FTERRORS_H__', which
+      must be  sometimes undefined by  the user to get  FreeType error
+      strings:  Both this  form and  the new  `FTERRORS_H_' macro  are
+      accepted for backward compatibility.
+
+    - Minor improvements mainly to the Type 1 driver.
+
+    - The  new CFF  engine now  supports all  Type 2  operators except
+      `random'.
+
+    - The macro `_STANDALONE_', used for  compiling the B/W and smooth
+      rasterizers  as   stand-alone  modules,  has  been   renamed  to
+      `STANDALONE_', since macro names starting with an underscore and
+      followed by an uppercase letter are reserved in both C and C++.
+
+    - Function  `FT_Library_SetLcdFilterWeights'  now  also  activates
+      custom LCD filter weights (instead of just adjusting them).
+
+    - Support for  `unpatented hinting'  has been  completely removed:
+      Consequently,  the two  functions `FT_Face_CheckTrueTypePatents'
+      and  `FT_Face_SetUnpatentedHinting'  now  return  always  false,
+      doing nothing.
+
+    - The `ftgamma' demo  program has been modernized;  the gamma grid
+      display has been moved from `ftview' to this program.
+
+    - In `ftview',  it is now possible to cycle through  the available
+      LCD filtering modes.
+
+
+======================================================================
+
+CHANGES BETWEEN 2.6.1 and 2.6.2
+
+  I. IMPORTANT CHANGES
+
+    - The auto-hinter now supports stem darkening, to be controlled by
+      the    new   `no-stem-darkening'    and   `darkening-parameters'
+      properties.   This is  an  experimental  feature contributed  by
+      Nikolaus Waxweiler, and  the interface might change  in a future
+      release.
+
+    - By default, stem darkening is now switched off (for both the CFF
+      engine and the  auto-hinter).  The main reason is  that you need
+      linear  alpha  blending  and  gamma correction  to  get  correct
+      rendering results, and  the latter is not yet  available in most
+      freely  available  rendering  stacks like  X11.   Applying  stem
+      darkening without proper gamma correction  leads to far too dark
+      rendering results.
+
+    - The   meaning  of   `FT_RENDER_MODE_LIGHT'  has   been  slightly
+      modified.   It  now  essentially  means `no  hinting  along  the
+      horizontal  axis'; in  particular,  no change  of glyph  advance
+      widths.  Consequently, the auto-hinter  is used for all scalable
+      font  formats  except  for  CFF.    It  is  planned  that  other
+      font-specific rendering engines (TrueType, Type 1) will follow.
+
+
+  II. MISCELLANEOUS
+
+    - The default  LCD filter  has been changed  to be  normalized and
+      color-balanced.
+
+    - For    better    compatibility   with    FontConfig,    function
+      `FT_Library_SetLcdFilter'  accepts   a  new   enumeration  value
+      `FT_LCD_FILTER_LEGACY1'   (which  has   the   same  meaning   as
+      `FT_LCD_FILTER_LEGACY').
+
+    - A large number of bugs have been detected by using the libFuzzer
+      framework,  which should  further  improve  handling of  invalid
+      fonts.  Thanks again to Kostya Serebryany and Bungeman!
+
+    - `TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES',  a   new  configuration
+      option, controls the maximum number of executed opcodes within a
+      bytecode program.  You don't want to change this except for very
+      special  situations (e.g.,  making a  library fuzzer  spend less
+      time to handle broken fonts).
+
+    - The smooth renderer has been made faster.
+
+    - The `ftstring' demo program now supports subpixel rendering; use
+      key `l' to cycle through the LCD modes.
+
+    - The `ftstring'  demo program now supports  colour rendering; use
+      the `space' key to cycle through various colour combinations.
+
+    - The graphical demo programs now use a default gamma value of 1.8
+      (instead of 1.2).

+   * @description:
+   *   Set or override certain (library or module-wide) properties on a
+   *   face-by-face basis.  Useful for finer-grained control and avoiding
+   *   locks on shared structures (threads can modify their own faces as
+   *   they see fit).
+   *
+   *   Contrary to @FT_Property_Set, this function uses @FT_Parameter so
+   *   that you can pass multiple properties to the target face in one call.
+   *   Note that only a subset of the available properties can be
+   *   controlled.
+   *
+   *   * @FT_PARAM_TAG_STEM_DARKENING (stem darkening, corresponding to the
+   *     property `no-stem-darkening' provided by the `autofit', `cff',
+   *     `type1', and `t1cid' modules; see @no-stem-darkening).
+   *
+   *   * @FT_PARAM_TAG_LCD_FILTER_WEIGHTS (LCD filter weights, corresponding
+   *     to function @FT_Library_SetLcdFilterWeights).
+   *
+   *   * @FT_PARAM_TAG_RANDOM_SEED (seed value for the CFF, Type~1, and CID
+   *     `random' operator, corresponding to the `random-seed' property
+   *     provided by the `cff', `type1', and `t1cid' modules; see
+   *     @random-seed).
+   *
+   *   Pass NULL as `data' in @FT_Parameter for a given tag to reset the
+   *   option and use the library or module default again.

+   *
+   * @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 CFF driver's module name is `cff'.
+   *
+   *   Available properties are @hinting-engine, @no-stem-darkening,
+   *   @darkening-parameters, and @random-seed, as documented in the
+   *   @properties section.
+   *
+   *
+   *   *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 subpixels 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 subpixels 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) Alignment 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.

+   *   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'.
+   *
+   *   A single property @interpreter-version is available, as documented in
+   *   the @properties section.
+   *
+   *   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_ _Backward_ _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
+   *   https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx.
+   *   This technique is not to be confused with ClearType compatible
+   *   widths.  ClearType backward 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 backward
+   *   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.

+   *   unless this property is set to TRUE.  The same is true for the CFF,
+   *   Type~1, and CID font modules if the `Adobe' engine is selected (which
+   *   is the default).
+   *
+   *   Stem darkening emboldens glyphs at smaller sizes to make them more
+   *   readable on common low-DPI screens when using linear alpha blending
+   *   and gamma correction, see @FT_Render_Glyph.  When not using linear
+   *   alpha blending and gamma correction, glyphs will appear heavy and
+   *   fuzzy!
+   *
+   *   Gamma correction essentially lightens fonts since shades of grey are
+   *   shifted to higher pixel values (=~higher brightness) to match the
+   *   original intention to the reality of our screens.  The side-effect is
+   *   that glyphs `thin out'.  Mac OS~X and Adobe's proprietary font
+   *   rendering library implement a counter-measure: stem darkening at
+   *   smaller sizes where shades of gray dominate.  By emboldening a glyph
+   *   slightly in relation to its pixel size, individual pixels get higher
+   *   coverage of filled-in outlines and are therefore `blacker'.  This
+   *   counteracts the `thinning out' of glyphs, making text remain readable
+   *   at smaller sizes.
+   *
+   *   By default, the Adobe engines for CFF, Type~1, and CID fonts darken
+   *   stems at smaller sizes, regardless of hinting, to enhance contrast. 
+   *   Setting this property, stem darkening gets switched off.
+   *
+   *   For the auto-hinter, stem-darkening is experimental currently and
+   *   thus switched off by default (this is, `no-stem-darkening' is set to
+   *   TRUE by default).  Total consistency with the CFF driver is not
+   *   achieved right now because the emboldening method differs and glyphs
+   *   must be scaled down on the Y-axis to keep outline points inside their
+   *   precomputed blue zones.  The smaller the size (especially 9ppem and
+   *   down), the higher the loss of emboldening versus the CFF driver.

+   *   Color and Gray ClearType are the two available variants of

+   *   Y-direction; the name used in the TrueType specification for this
+   *   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).
+   *
+   *   Keep in mind that the features of the above interpreter versions
+   *   might not map exactly to FreeType features or behavior because it is
+   *   a fundamentally different library with different internals.

+   *   If subpixel hinting is on, many TrueType bytecode instructions behave

+   *   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.

+   *
+   *   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
+   *   warping (omitting the error handling).
+   *
+   *   {
+   *     FT_Library  library;
+   *     FT_Bool     warping = 1;

+   *   }
+   *
+   * @note:
+   *   This property can be used with @FT_Property_Get also.
+   *
+   *   This property can be set via the `FREETYPE_PROPERTIES' environment
+   *   variable (using values 1 and 0 for `on' and `off', respectively).
+   *
+   *   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
+   *   change its value before rendering any face.  Otherwise, you should
+   *   reload all faces that get auto-hinted in `normal' hinting mode.

    *   LCD Filtering
    *
    * @abstract:
-   *   Reduce color fringes of LCD-optimized bitmaps.
+   *   Reduce color fringes of subpixel-rendered bitmaps.
    *
    * @description:
-   *   The @FT_Library_SetLcdFilter API can be used to specify a low-pass
-   *   filter, which is then applied to LCD-optimized bitmaps generated
-   *   through @FT_Render_Glyph.  This is useful to reduce color fringes
-   *   that would occur with unfiltered rendering.
-   *
-   *   Note that no filter is active by default, and that this function is
-   *   *not* implemented in default builds of the library.  You need to
-   *   #define FT_CONFIG_OPTION_SUBPIXEL_RENDERING in your `ftoption.h' file
-   *   in order to activate it.
-   *
-   *   FreeType generates alpha coverage maps, which are linear by nature.
-   *   For instance, the value 0x80 in bitmap representation means that
-   *   (within numerical precision) 0x80/0xFF fraction of that pixel is
-   *   covered by the glyph's outline.  The blending function for placing
-   *   text over a background is
-   *
-   *   {
-   *     dst = alpha * src + (1 - alpha) * dst    ,
-   *   }
-   *
-   *   which is known as OVER.  However, when calculating the output of the
-   *   OVER operator, the source colors should first be transformed to a
-   *   linear color space, then alpha blended in that space, and transformed
-   *   back to the output color space.
-   *
-   *   When linear light blending is used, the default FIR5 filtering
-   *   weights (as given by FT_LCD_FILTER_DEFAULT) are no longer optimal, as
-   *   they have been designed for black on white rendering while lacking
-   *   gamma correction.  To preserve color neutrality, weights for a FIR5
-   *   filter should be chosen according to two free parameters `a' and `c',
-   *   and the FIR weights should be
-   *
-   *   {
-   *     [a - c, a + c, 2 * a, a + c, a - c]    .
-   *   }
-   *
-   *   This formula generates equal weights for all the color primaries
-   *   across the filter kernel, which makes it colorless.  One suggested
-   *   set of weights is
-   *
-   *   {
-   *     [0x10, 0x50, 0x60, 0x50, 0x10]    ,
-   *   }
-   *
-   *   where `a' has value 0x30 and `b' value 0x20.  The weights in filter
-   *   may have a sum larger than 0x100, which increases coloration slightly
-   *   but also improves contrast.
+   *   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.
+   *
+   *   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.

+     * 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.

+   * A `CF2_Blues' object stores the blue zones (horizontal alignment
+   * zones) of a font.  These are specified in the CFF private dictionary
+   * 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
+   * alignment point.  This alignment is recorded in device space in
+   * `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

+   * 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 preservation 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 propagate 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;
+   *

+ftfuzzer
+========
+
+
+ftfuzzer.cc
+-----------
+
+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.
+
+
+ftmutator.cc
+------------
+
+FreeType has the  ability to `attach' auxiliary files to  a font file,
+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/*

 This program expects a set of directories containing good fonts, and a set
 of extensions of fonts to be tested.  It will randomly pick a font, copy it,

   --error-count <cnt>      Introduce <cnt> single-byte errors into the
-                           erroneous fonts.
+                           erroneous fonts (default: 1).

+                           debugged more easily.
+
+The default font extensions tested by ftrandom are
+
+  .ttf .otf .ttc .cid .pfb .pfa .bdf .pcf .pfr .fon .otb .cff
+
+The default font directory is controlled by the macro `GOOD_FONTS_DIR' in
+the source code (and can be thus specified during compilation); its default
+value is
+
+  /usr/local/share/fonts
+
+The default result directory is `results' (in the current directory).
+
+
+Compilation
+-----------
+
+Two possible solutions.
+
+. Run ftrandom within a debugging tool like `valgrind' to catch various
+  memory issues.
+
+. Compile FreeType with sanitizer flags as provided by gcc or clang, for
+  example, then link it with ftrandom.

+     * FreeType supports ClearType-like hinting of TrueType fonts through
+     * the version 40 interpreter.  This is achieved through several hacks
+     * in the base (v35) interpreter, as detailed below.
+     *
+     * ClearType is an umbrella term for several rendering techniques
+     * employed by Microsoft's various GUI and rendering toolkit
+     * implementations, most importantly: subpixel rendering for using the
+     * RGB subpixels of LCDs to approximately triple the perceived
+     * resolution on the x-axis and subpixel hinting for positioning stems
+     * on subpixel borders.  TrueType programming is explicit, i.e., fonts
+     * must be programmed to take advantage of ClearType's possibilities.
+     *
+     * When ClearType was introduced, it seemed unlikely that all fonts
+     * would be reprogrammed, so Microsoft decided to implement a backward
+     * compatibility mode.  It employs several simple to complicated
+     * assumptions and tricks, many of them font-dependent, that modify the
+     * interpretation of the bytecode contained in these fonts to retrofit
+     * them into a ClearType-y look.  The quality of the results varies.
+     * Most (web)fonts that were released since then have come to rely on
+     * these hacks to render correctly, even some of Microsoft's flagship
+     * fonts (e.g., Calibri, Cambria, Segoe UI).
+     *
+     * FreeType's minimal subpixel hinting code (interpreter version 40)
+     * employs a small list of font-agnostic hacks loosely based on the
+     * public information available on Microsoft's compatibility mode[2].
+     * The focus is on modern (web)fonts rather than legacy fonts that were
+     * made for monochrome rendering.  It will not match ClearType rendering
+     * exactly.  Unlike the `Infinality' code (interpreter version 38) that
+     * came before, it will not try to toggle hacks for specific fonts for
+     * performance and complexity reasons.  It will fall back to version 35
+     * behavior for tricky fonts[1] or when monochrome rendering is
+     * requested.
+     *
+     * Major hacks
+     *
+     * - Any point movement on the x axis is ignored (cf. `Direct_Move' and
+     *   `Direct_Move_X').  This has the smallest code footprint and single
+     *   biggest effect.  The ClearType way to increase resolution is
+     *   supersampling the x axis, the FreeType way is ignoring instructions
+     *   on the x axis, which gives the same result in the majority of
+     *   cases.
+     *
+     * - Points are not moved post-IUP (neither on the x nor on the y axis),
+     *   except the x component of diagonal moves post-IUP (cf.
+     *   `Direct_Move', `Direct_Move_Y', `Move_Zp2_Point').  Post-IUP
+     *   changes are commonly used to `fix' pixel patterns which has little
+     *   use outside monochrome rendering.
+     *
+     * - SHPIX and DELTAP don't execute unless moving a composite on the
+     *   y axis or moving a previously y touched point.  SHPIX additionally
+     *   denies movement on the x axis (cf. `Ins_SHPIX' and `Ins_DELTAP').
+     *   Both instructions are commonly used to `fix' pixel patterns for
+     *   monochrome or Windows's GDI rendering but make little sense for
+     *   FreeType rendering.  Both can distort the outline.  See [2] for
+     *   details.
+     *
+     * - The hdmx table and modifications to phantom points are ignored.
+     *   Bearings and advance widths remain unchanged (except rounding them
+     *   outside the interpreter!), cf. `compute_glyph_metrics' and
+     *   `TT_Hint_Glyph'.  Letting non-native-ClearType fonts modify spacing
+     *   might mess up spacing.
+     *
+     * Minor hacks
+     *
+     * - FLIPRGON, FLIPRGOFF, and FLIPPT don't execute post-IUP.  This
+     *   prevents dents in e.g. Arial-Regular's `D' and `G' glyphs at
+     *   various sizes.
+     *
+     * (Post-IUP is the state after both IUP[x] and IUP[y] have been
+     * executed.)
+     *
+     * The best results are achieved for fonts that were from the outset
+     * designed with ClearType in mind, meaning they leave the x axis mostly
+     * alone and don't mess with the `final' outline to produce more
+     * pleasing pixel patterns.  The harder the designer tried to produce
+     * very specific patterns (`superhinting') for pre-ClearType-displays,
+     * the worse the results.
+     *
+     * Microsoft defines a way to turn off backward compatibility and
+     * interpret instructions as before (called `native ClearType')[2][3].
+     * The font designer then regains full control and is responsible for
+     * making the font work correctly with ClearType without any
+     * hand-holding by the interpreter or rasterizer[4].  The v40
+     * interpreter assumes backward compatibility by default, which can be
+     * turned off the same way by executing the following in the control
+     * program (cf. `Ins_INSTCTRL').
+     *
+     *   #PUSH 4,3
+     *   INSTCTRL[]
+     *
+     * [1] Tricky fonts as FreeType defines them rely on the bytecode
+     *     interpreter to display correctly.  Hacks can interfere with them,
+     *     so they get treated like native ClearType fonts (v40 with
+     *     backward compatibility turned off).  Cf. `TT_RunIns'.
+     *
+     * [2] Proposed by Microsoft's Greg Hitchcock in
+     *     https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx
+     *
+     * [3] Beat Stamm describes it in more detail:
+     *     http://www.beatstamm.com/typography/RTRCh4.htm#Sec12
+     *
+     * [4] The list of `native ClearType' fonts is small at the time of this
+     *     writing; I found the following on a Windows 10 Update 1511
+     *     installation: Constantia, Corbel, Sitka, Malgun Gothic, Microsoft
+     *     JhengHei (Bold and UI Bold), Microsoft YaHei (Bold and UI Bold),
+     *     SimSun, NSimSun, and Yu Gothic.

+2.0.2
+=====
+
+### Significant changes relative to 2.0.1:
+
+1. Fixed a regression introduced by 2.0.1[5] that prevented a runtime search
+path (rpath) from being embedded in the libjpeg-turbo shared libraries and
+executables for macOS and iOS.  This caused a fatal error of the form
+"dyld: Library not loaded" when attempting to use one of the executables,
+unless `DYLD_LIBRARY_PATH` was explicitly set to the location of the
+libjpeg-turbo shared libraries.
+
+2. Fixed an integer overflow and subsequent segfault (CVE-2018-20330) that
+occurred when attempting to load a BMP file with more than 1 billion pixels
+using the `tjLoadImage()` function.
+
+3. Fixed a buffer overrun (CVE-2018-19664) that occurred when attempting to
+decompress a specially-crafted malformed JPEG image to a 256-color BMP using
+djpeg.
+
+4. Fixed a floating point exception that occurred when attempting to
+decompress a specially-crafted malformed JPEG image with a specified image
+width or height of 0 using the C version of TJBench.
+
+5. The TurboJPEG API will now decompress 4:4:4 JPEG images with 2x1, 1x2, 3x1,
+or 1x3 luminance and chrominance sampling factors.  This is a non-standard way
+of specifying 1x subsampling (normally 4:4:4 JPEGs have 1x1 luminance and
+chrominance sampling factors), but the JPEG format and the libjpeg API both
+allow it.
+
+6. Fixed a regression introduced by 2.0 beta1[7] that caused djpeg to generate
+incorrect PPM images when used with the `-colors` option.
+
+7. Fixed an issue whereby a static build of libjpeg-turbo (a build in which
+`ENABLE_SHARED` is `0`) could not be installed using the Visual Studio IDE.
+
+8. Fixed a severe performance issue in the Loongson MMI SIMD extensions that
+occurred when compressing RGB images whose image rows were not 64-bit-aligned.
+
+
+2.0.1
+=====
+
+### Significant changes relative to 2.0.0:
+
+1. Fixed a regression introduced with the new CMake-based Un*x build system,
+whereby jconfig.h could cause compiler warnings of the form
+`"HAVE_*_H" redefined` if it was included by downstream Autotools-based
+projects that used `AC_CHECK_HEADERS()` to check for the existence of locale.h,

+2. The `jsimd_quantize_float_dspr2()` and `jsimd_convsamp_float_dspr2()`
+functions in the MIPS DSPr2 SIMD extensions are now disabled at compile time
+if the soft float ABI is enabled.  Those functions use instructions that are
+incompatible with the soft float ABI.
+
+3. Fixed a regression in the SIMD feature detection code, introduced by
+the AVX2 SIMD extensions (2.0 beta1[1]), that caused libjpeg-turbo to crash on
+Windows 7 if Service Pack 1 was not installed.
+
+4. Fixed out-of-bounds read in cjpeg that occurred when attempting to compress
+a specially-crafted malformed color-index (8-bit-per-sample) Targa file in
+which some of the samples (color indices) exceeded the bounds of the Targa
+file's color table.
+
+5. Fixed an issue whereby installing a fully static build of libjpeg-turbo
+(a build in which `CFLAGS` contains `-static` and `ENABLE_SHARED` is `0`) would
+fail with "No valid ELF RPATH or RUNPATH entry exists in the file."

-XVI. Y2K Compliance in libpng
-
-Since the PNG Development group is an ad-hoc body, we can't make
-an official declaration.
-
-This is your unofficial assurance that libpng from version 0.71 and
-upward through 1.6.34 are Y2K compliant.  It is my belief that earlier
-versions were also Y2K compliant.
-
-Libpng only has two year fields.  One is a 2-byte unsigned integer
-that will hold years up to 65535.  The other, which is deprecated,
-holds the date in text format, and will hold years up to 9999.
-
-The integer is
-    "png_uint_16 year" in png_time_struct.
-
-The string is
-    "char time_buffer[29]" in png_struct.  This is no longer used
-in libpng-1.6.x and will be removed from libpng-1.7.0.
-
-There are seven time-related functions:
-
-    png_convert_to_rfc_1123_buffer() in png.c
-      (formerly png_convert_to_rfc_1152() in error, and
-      also formerly png_convert_to_rfc_1123())
-    png_convert_from_struct_tm() in pngwrite.c, called
-      in pngwrite.c
-    png_convert_from_time_t() in pngwrite.c
-    png_get_tIME() in pngget.c
-    png_handle_tIME() in pngrutil.c, called in pngread.c
-    png_set_tIME() in pngset.c
-    png_write_tIME() in pngwutil.c, called in pngwrite.c
-
-All appear to handle dates properly in a Y2K environment.  The
-png_convert_from_time_t() function calls gmtime() to convert from system
-clock time, which returns (year - 1900), which we properly convert to
-the full 4-digit year.  There is a possibility that applications using
-libpng are not passing 4-digit years into the png_convert_to_rfc_1123()
-function, or that they are incorrectly passing only a 2-digit year
-instead of "year - 1900" into the png_convert_from_struct_tm() function,
-but this is not under our control.  The libpng documentation has always
-stated that it works with 4-digit years, and the APIs have been
-documented as such.
-
-The tIME chunk itself is also Y2K compliant.  It uses a 2-byte unsigned
-integer to hold the year, and can hold years as large as 65535.
-
-zlib, upon which libpng depends, is also Y2K compliant.  It contains
-no date-related code.

- * Y2K compliance in libpng:
- * =========================
- *
- *    September 29, 2017
- *
- *    Since the PNG Development group is an ad-hoc body, we can't make
- *    an official declaration.
- *
- *    This is your unofficial assurance that libpng from version 0.71 and
- *    upward through 1.6.34 are Y2K compliant.  It is my belief that
- *    earlier versions were also Y2K compliant.
- *
- *    Libpng only has two year fields.  One is a 2-byte unsigned integer
- *    that will hold years up to 65535.  The other, which is deprecated,
- *    holds the date in text format, and will hold years up to 9999.
- *
- *    The integer is
- *        "png_uint_16 year" in png_time_struct.
- *
- *    The string is
- *        "char time_buffer[29]" in png_struct.  This is no longer used
- *    in libpng-1.6.x and will be removed from libpng-1.7.0.
- *
- *    There are seven time-related functions:
- *        png.c: png_convert_to_rfc_1123_buffer() in png.c
- *          (formerly png_convert_to_rfc_1123() prior to libpng-1.5.x and
- *          png_convert_to_rfc_1152() in error prior to libpng-0.98)
- *        png_convert_from_struct_tm() in pngwrite.c, called in pngwrite.c
- *        png_convert_from_time_t() in pngwrite.c
- *        png_get_tIME() in pngget.c
- *        png_handle_tIME() in pngrutil.c, called in pngread.c
- *        png_set_tIME() in pngset.c
- *        png_write_tIME() in pngwutil.c, called in pngwrite.c
- *
- *    All handle dates properly in a Y2K environment.  The
- *    png_convert_from_time_t() function calls gmtime() to convert from system
- *    clock time, which returns (year - 1900), which we properly convert to
- *    the full 4-digit year.  There is a possibility that libpng applications
- *    are not passing 4-digit years into the png_convert_to_rfc_1123_buffer()
- *    function, or that they are incorrectly passing only a 2-digit year
- *    instead of "year - 1900" into the png_convert_from_struct_tm() function,
- *    but this is not under our control.  The libpng documentation has always
- *    stated that it works with 4-digit years, and the APIs have been
- *    documented as such.
- *
- *    The tIME chunk itself is also Y2K compliant.  It uses a 2-byte unsigned
- *    integer to hold the year, and can hold years as large as 65535.
- *
- *    zlib, upon which libpng depends, is also Y2K compliant.  It contains
- *    no date-related code.

+** The cells in this array are the divider cell or cells from the pParent
+** page plus up to three child pages.  There are a total of nCell cells.
+**
+** pRef is a pointer to one of the pages that contributes cells.  This is
+** used to access information such as MemPage.intKey and MemPage.pBt->pageSize
+** which should be common to all pages that contribute cells to this array.
+**
+** apCell[] and szCell[] hold, respectively, pointers to the start of each
+** cell and the size of each cell.  Some of the apCell[] pointers might refer
+** to overflow cells.  In other words, some apCel[] pointers might not point
+** to content area of the pages.
+**
+** A szCell[] of zero means the size of that cell has not yet been computed.
+**
+** The cells come from as many as four different pages:
+**
+**             -----------
+**             | Parent  |
+**             -----------
+**            /     |     \
+**           /      |      \
+**  ---------   ---------   ---------
+**  |Child-1|   |Child-2|   |Child-3|
+**  ---------   ---------   ---------
+**
+** The order of cells is in the array is for an index btree is:
+**
+**       1.  All cells from Child-1 in order
+**       2.  The first divider cell from Parent
+**       3.  All cells from Child-2 in order
+**       4.  The second divider cell from Parent
+**       5.  All cells from Child-3 in order
+**
+** For a table-btree (with rowids) the items 2 and 4 are empty because
+** content exists only in leaves and there are no divider cells.
+**
+** For an index btree, the apEnd[] array holds pointer to the end of page
+** for Child-1, the Parent, Child-2, the Parent (again), and Child-3,
+** respectively. The ixNx[] array holds the number of cells contained in
+** each of these 5 stages, and all stages to the left.  Hence:
+**
+**    ixNx[0] = Number of cells in Child-1.
+**    ixNx[1] = Number of cells in Child-1 plus 1 for first divider.
+**    ixNx[2] = Number of cells in Child-1 and Child-2 + 1 for 1st divider.
+**    ixNx[3] = Number of cells in Child-1 and Child-2 + both divider cells
+**    ixNx[4] = Total number of cells.
+**
+** For a table-btree, the concept is similar, except only apEnd[0]..apEnd[2]
+** are used and they point to the leaf pages only, and the ixNx value are:
+**
+**    ixNx[0] = Number of cells in Child-1.
+**    ixNx[1] = Number of cells in Child-1 and Child-2 + 1 for 1st divider.
+**    ixNx[2] = Number of cells in Child-1 and Child-2 + both divider cells

+** AND-connected terms that are not part of a ON clause from a LEFT JOIN)
+** then throughout the query replace all other occurrences of COLUMN
+** with CONSTANT within the WHERE clause.
+**
+** For example, the query:
+**
+**      SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=t1.a AND t3.c=t2.b
+**
+** Is transformed into

+**      SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=39 AND t3.c=39
+**
+** Return true if any transformations where made and false if not.
+**
+** Implementation note:  Constant propagation is tricky due to affinity
+** and collating sequence interactions.  Consider this example:
+**
+**    CREATE TABLE t1(a INT,b TEXT);
+**    INSERT INTO t1 VALUES(123,'0123');
+**    SELECT * FROM t1 WHERE a=123 AND b=a;
+**    SELECT * FROM t1 WHERE a=123 AND b=123;
+**
+** The two SELECT statements above should return different answers.  b=a
+** is alway true because the comparison uses numeric affinity, but b=123
+** is false because it uses text affinity and '0123' is not the same as '123'.
+** To work around this, the expression tree is not actually changed from
+** "b=a" to "b=123" but rather the "a" in "b=a" is tagged with EP_FixedCol
+** and the "123" value is hung off of the pLeft pointer.  Code generator
+** routines know to generate the constant "123" instead of looking up the
+** column value.  Also, to avoid collation problems, this optimization is
+** only attempted if the "a=123" term uses the default BINARY collation.

+** SELECT REWRITING
+**
+**   Any SELECT statement that contains one or more window functions in
+**   either the select list or ORDER BY clause (the only two places window
+**   functions may be used) is transformed by function sqlite3WindowRewrite()
+**   in order to support window function processing. For example, with the
+**   schema:
+**
+**     CREATE TABLE t1(a, b, c, d, e, f, g);
+**
+**   the statement:
+**
+**     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM t1 ORDER BY e;
+**
+**   is transformed to:
+**
+**     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM (
+**         SELECT a, e, c, d, b FROM t1 ORDER BY c, d
+**     ) ORDER BY e;
+**
+**   The flattening optimization is disabled when processing this transformed
+**   SELECT statement. This allows the implementation of the window function
+**   (in this case max()) to process rows sorted in order of (c, d), which
+**   makes things easier for obvious reasons. More generally:
+**
+**     * FROM, WHERE, GROUP BY and HAVING clauses are all moved to 
+**       the sub-query.
+**
+**     * ORDER BY, LIMIT and OFFSET remain part of the parent query.
+**
+**     * Terminals from each of the expression trees that make up the 
+**       select-list and ORDER BY expressions in the parent query are
+**       selected by the sub-query. For the purposes of the transformation,
+**       terminals are column references and aggregate functions.
+**
+**   If there is more than one window function in the SELECT that uses
+**   the same window declaration (the OVER bit), then a single scan may
+**   be used to process more than one window function. For example:
+**
+**     SELECT max(b) OVER (PARTITION BY c ORDER BY d), 
+**            min(e) OVER (PARTITION BY c ORDER BY d) 
+**     FROM t1;
+**
+**   is transformed in the same way as the example above. However:
+**
+**     SELECT max(b) OVER (PARTITION BY c ORDER BY d), 
+**            min(e) OVER (PARTITION BY a ORDER BY b) 
+**     FROM t1;
+**
+**   Must be transformed to:
+**
+**     SELECT max(b) OVER (PARTITION BY c ORDER BY d) FROM (
+**         SELECT e, min(e) OVER (PARTITION BY a ORDER BY b), c, d, b FROM
+**           SELECT a, e, c, d, b FROM t1 ORDER BY a, b
+**         ) ORDER BY c, d
+**     ) ORDER BY e;
+**
+**   so that both min() and max() may process rows in the order defined by
+**   their respective window declarations.
+**
+** INTERFACE WITH SELECT.C
+**
+**   When processing the rewritten SELECT statement, code in select.c calls
+**   sqlite3WhereBegin() to begin iterating through the results of the
+**   sub-query, which is always implemented as a co-routine. It then calls
+**   sqlite3WindowCodeStep() to process rows and finish the scan by calling
+**   sqlite3WhereEnd().
+**
+**   sqlite3WindowCodeStep() generates VM code so that, for each row returned
+**   by the sub-query a sub-routine (OP_Gosub) coded by select.c is invoked.
+**   When the sub-routine is invoked:
+**
+**     * The results of all window-functions for the row are stored
+**       in the associated Window.regResult registers.
+**
+**     * The required terminal values are stored in the current row of
+**       temp table Window.iEphCsr.
+**
+**   In some cases, depending on the window frame and the specific window
+**   functions invoked, sqlite3WindowCodeStep() caches each entire partition
+**   in a temp table before returning any rows. In other cases it does not.
+**   This detail is encapsulated within this file, the code generated by
+**   select.c is the same in either case.
+**
+** BUILT-IN WINDOW FUNCTIONS
+**
+**   This implementation features the following built-in window functions:
+**
+**     row_number()
+**     rank()
+**     dense_rank()
+**     percent_rank()
+**     cume_dist()
+**     ntile(N)
+**     lead(expr [, offset [, default]])
+**     lag(expr [, offset [, default]])
+**     first_value(expr)
+**     last_value(expr)
+**     nth_value(expr, N)
+**   
+**   These are the same built-in window functions supported by Postgres. 
+**   Although the behaviour of aggregate window functions (functions that
+**   can be used as either aggregates or window funtions) allows them to
+**   be implemented using an API, built-in window functions are much more
+**   esoteric. Additionally, some window functions (e.g. nth_value()) 
+**   may only be implemented by caching the entire partition in memory.
+**   As such, some built-in window functions use the same API as aggregate
+**   window functions and some are implemented directly using VDBE 
+**   instructions. Additionally, for those functions that use the API, the
+**   window frame is sometimes modified before the SELECT statement is
+**   rewritten. For example, regardless of the specified window frame, the
+**   row_number() function always uses:
+**
+**     ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
+**
+**   See sqlite3WindowUpdate() for details.
+**
+**   As well as some of the built-in window functions, aggregate window
+**   functions min() and max() are implemented using VDBE instructions if
+**   the start of the window frame is declared as anything other than 
+**   UNBOUNDED PRECEDING.

-libxkbcommon 0.4.1
-==================
-
-- Converted README to markdown and added a Quick Guide to the
-  documentation, which breezes through the most common parts of
-  xkbcommon.
-
-- Added two new functions, xkb_state_key_get_utf{8,32}(). They
-  combine the operations of xkb_state_key_get_syms() and
-  xkb_keysym_to_utf{8,32}(), and provide a nicer interface for it
-  (espcially for multiple-keysyms-per-level).
-
-- The xkb_state_key_get_utf{8,32}() functions now apply Control
-  transformation: when the Control modifier is active, the string
-  is converted to an appropriate control character.
-  This matches the behavior of libX11's XLookupString(3), and
-  required by the XKB specification:
-  http://www.x.org/releases/current/doc/kbproto/xkbproto.html#Interpreting_the_Control_Modifier
-
-  https://bugs.freedesktop.org/show_bug.cgi?id=75892
-
-- The consumed modifiers for a key are now calculated similarly
-  to libX11. The previous behavior caused a bug where Shift would
-  not cancel an active Caps Lock.
-
-- Make xkbcommon-x11 work with the keymap reported by the XQuartz
-  X server.
-
-  https://bugs.freedesktop.org/show_bug.cgi?id=75798
-
-- Reduce memory usage during keymap compilation some more.
-
-- New API:
-  xkb_state_key_get_consumed_mods()
-  xkb_state_key_get_utf8()
-  xkb_state_key_get_utf32()
-
-- Deprecated API:
-  XKB_MAP_COMPILE_PLACEHOLDER, XKB_MAP_NO_FLAGS
-    use XKB_KEYMAP_NO_FLAGS instead.
-
-- Bug fixes.
-
-libxkbcommon 0.4.0
-==================
-
-- Add a new add-on library, xkbcommon-x11, to support creating keymaps
-  with the XKB X11 protocol, by querying the X server directly.
-  See the xkbcommon/xkbcommon-x11.h header file for more details.
-  This library requires libxcb-xkb >= 1.10, and is enabled by default.
-  It can be disabled with the --disable-x11 configure switch.
-  Distributions are encouraged to split the necessary files for this
-  library (libxkbcommon-x11.so, xkbcommon-x11.pc, xkbcommon/xkbcommon-x11.h)
-  to a separate package, such that the main package does not depend on
-  X11 libraries.
-
-- Fix the keysym <-> name lookup table to not require huge amounts of
-  relocations.
-
-- Fix a bug in the keysym <-> name lookup, whereby lookup might fail in
-  some rare cases.
-
-- Reduce memory usage during keymap compilation.
-
-- New API:
-  New keysyms from xproto 7.0.25 (German T3 layout keysyms).
-  XKB_MOD_NAME_NUM for the usual NumLock modifier.
-  xkb_x11_* types and functions, XKB_X11_* constants.
-
-
-libxkbcommon 0.3.2
-==================
-
-- Log messages from the library now look like "xkbcommon: ERROR" by
-  default, instead of xkbcomp-like "Error:   ".
-
-- Apply capitalization transformation on keysyms in
-  xkb_keysym_get_one_sym(), to match the behavior specified in the XKB
-  specification:
-  http://www.x.org/releases/current/doc/kbproto/xkbproto.html#Interpreting_the_Lock_Modifier
-
-- Support byacc for generating the parser, in addition to Bison.
-
-- New API:
-  XKB_KEY_XF86AudioMicMute keysym from xproto 7.0.24.
-  XKB_KEYSYM_NO_FLAGS
-  XKB_CONTEXT_NO_FLAGS
-  XKB_MAP_COMPILE_NO_FLAGS
-
-- Bug fixes.
-
-
-libxkbcommon 0.3.1
-==================
-
-- Replace the flex scanner with a hand-written one. flex is no longer
-  a build requirement.
-
-- New API:
-  xkb_keymap_min_keycode()
-  xkb_keymap_max_keycode()
-  xkb_keymap_key_for_each()
-
-
-libxkbcommon 0.3.0
-==================
-
-- Allow passing NULL to *_unref() functions; do nothing instead of
-  crashing.
-
-- The functions xkb_keymap_num_levels_for_key() and
-  xkb_keymap_get_syms_by_level() now allow out-of-range values for the
-  'layout' parameter. The functions now wrap the value around the number
-  of layouts instead of failing.
-
-- The function xkb_keysym_get_name() now types unicode keysyms in
-  uppercase and 0-padding, to match the format used by XKeysymToString().
-
-- Building Linux-specific tests is no longer attempted on non-Linux
-  environments.
-
-- The function xkb_keymap_new_from_names() now accepts a NULL value for
-  the 'names' parameter, instead of failing. This is equivalent to passing
-  a 'struct xkb_rule_names' with all fields set to NULL.
-
-- New API:
-  xkb_keymap_new_from_buffer()
-
-- Bug fixes.

-# libxkbcommon
-
-xkbcommon is a keymap compiler and support library which processes a
-reduced subset of keymaps as defined by the XKB specification.  Primarily,
-a keymap is created from a set of Rules/Model/Layout/Variant/Options names,
-processed through an XKB ruleset, and compiled into a struct xkb_keymap,
-which is the base type for all xkbcommon operations.
-
-From an xkb_keymap, an xkb_state object is created which holds the current
-state of all modifiers, groups, LEDs, etc, relating to that keymap.  All
-key events must be fed into the xkb_state object using xkb_state_update_key().
-Once this is done, the xkb_state object will be properly updated, and the
-keysyms to use can be obtained with xkb_state_key_get_syms().
-
-libxkbcommon does not distribute a dataset itself, other than for testing
-purposes.  The most common dataset is xkeyboard-config, as used by all
-current distributions for their X11 XKB data.  More information on
-xkeyboard-config is available here:
-    http://www.freedesktop.org/wiki/Software/XKeyboardConfig
-
-## Quick Guide
-
-See [Quick Guide](doc/quick-guide.md).
-
-## API
-
-While xkbcommon's API is somewhat derived from the classic XKB API as found
-in X11/extensions/XKB.h and friends, it has been substantially reworked to
-expose fewer internal details to clients.  The supported API is available
-in the xkbcommon/xkbcommon-*.h files.  Additional support is provided for
-X11 (XCB) clients, in the xkbcommon-x11 library, xkbcommon/xkbcommon-x11.h.
-
-The xkbcommon API and ABI are stable. We will attempt to not break ABI during
-a minor release series, so applications written against 0.1.0 should be
-completely compatible with 0.5.3, but not necessarily with 1.0.0.  However, new
-symbols may be introduced in any release.  Thus, anyone packaging xkbcommon
-should make sure any package depending on it depends on a release greater than
-or equal to the version it was built against (or earlier, if it doesn't use
-any newly-introduced symbols), but less than the next major release.
-
-## Relation to X11
-
-Relative to the XKB 1.1 specification implemented in current X servers,
-xkbcommon has removed support for some parts of the specification which
-introduced unnecessary complications.  Many of these removals were in fact
-not implemented, or half-implemented at best, as well as being totally
-unused in the standard dataset.
-
-Notable removals:
-- geometry support
-  + there were very few geometry definitions available, and while
-    xkbcommon was responsible for parsing this insanely complex format,
-    it never actually did anything with it
-  + hopefully someone will develop a companion library which supports
-    keyboard geometries in a more useful format
-- KcCGST (keycodes/compat/geometry/symbols/types) API
-  + use RMLVO instead; KcCGST is now an implementation detail
-  + including pre-defined keymap files
-- XKM support
-  + may come in an optional X11 support/compatibility library
-- around half of the interpret actions
-  + pointer device, message and redirect actions in particular
-- non-virtual modifiers
-  + core and virtual modifiers have been collapsed into the same
-    namespace, with a 'significant' flag that largely parallels the
-    core/virtual split
-- radio groups
-  + completely unused in current keymaps, never fully implemented
-- overlays
-  + almost completely unused in current keymaps
-- key behaviors
-  + used to implement radio groups and overlays, and to deal with things
-    like keys that physically lock; unused in current keymaps
-- indicator behaviours such as LED-controls-key
-  + the only supported LED behaviour is key-controls-LED; again this
-    was never really used in current keymaps
-
-Notable additions:
-- 32-bit keycodes
-- extended number of modifiers
-- extended number of groups
-- multiple keysyms per level
-  + this requires incompatible dataset changes, such that X11 would
-    not be able to parse these
-

-/* This module converts keysym values into the corresponding ISO 10646
- * (UCS, Unicode) values.
- *
- * The array keysymtab[] contains pairs of X11 keysym values for graphical
- * characters and the corresponding Unicode value. The function
- * keysym2ucs() maps a keysym onto a Unicode value using a binary search,
- * therefore keysymtab[] must remain SORTED by keysym value.
- *
- * The keysym -> UTF-8 conversion will hopefully one day be provided
- * by Xlib via XmbLookupString() and should ideally not have to be
- * done in X applications. But we are not there yet.
- *
- * We allow to represent any UCS character in the range U-00000000 to
- * U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
- * This admittedly does not cover the entire 31-bit space of UCS, but
- * it does cover all of the characters up to U-10FFFF, which can be
- * represented by UTF-16, and more, and it is very unlikely that higher
- * UCS codes will ever be assigned by ISO. So to get Unicode character
- * U+ABCD you can directly use keysym 0x0100abcd.
- *
- * NOTE: The comments in the table below contain the actual character
- * encoded in UTF-8, so for viewing and editing best use an editor in
- * UTF-8 mode.

-/**
- * Parse an include statement. Each call returns a file name, along with
- * (possibly) a specific map in the file, an explicit group designator, and
- * the separator from the next file, used to determine the merge mode.
- *
- * @param str_inout Input statement, modified in-place. Should be passed in
- * repeatedly. If str_inout is NULL, the parsing has completed.
- *
- * @param file_rtrn Set to the name of the include file to be used. Combined
- * with an enum xkb_file_type, this determines which file to look for in the
- * include path.
- *
- * @param map_rtrn Set to the string between '(' and ')', if any. This will
- * result in the compilation of a specific named map within the file (e.g.
- * xkb_symbols "basic" { ... }) , as opposed to the default map of the file.
- *
- * @param nextop_rtrn Set to the next operation in the complete statement,
- * which is '\0' if it's the last file or '+' or '|' if there are more.
- * Separating the files with '+' sets the merge mode to MERGE_MODE_OVERRIDE,
- * while '|' sets the merge mode to MERGE_MODE_AUGMENT.
- *
- * @param extra_data Set to the string after ':', if any. Currently the
- * extra data is only used for setting an explicit group index for a symbols
- * file.
- *
- * @return true if parsing was successful, false for an illegal string.
- *
- * Example: "evdev+aliases(qwerty):2"
- *      str_inout = "aliases(qwerty):2"
- *      file_rtrn = "evdev"
- *      map_rtrn = NULL
- *      nextop_retrn = "+"
- *      extra_data = NULL
- *
- * 2nd run with "aliases(qwerty):2"
- *      str_inout = NULL
- *      file_rtrn = "aliases"
- *      map_rtrn = "qwerty"
- *      nextop_retrn = ""
- *      extra_data = "2"

-     - The only way there can be no lookahead present (in yychar) is if
-       this state is a consistent state with a default action.  Thus,
-       detecting the absence of a lookahead is sufficient to determine
-       that there is no unexpected or expected token to report.  In that
-       case, just report a simple "syntax error".
-     - Don't assume there isn't a lookahead just because this state is a
-       consistent state with a default action.  There might have been a

-/*
- * The "X11 Window System Protocol" standard defines in Appendix A the
- * keysym codes. These 29-bit integer values identify characters or
- * functions associated with each key (e.g., via the visible
- * engraving) of a keyboard layout. This file assigns mnemonic macro
- * names for these keysyms.
- *
- * This file is also compiled (by src/util/makekeys.c in libX11) into
- * hash tables that can be accessed with X11 library functions such as
- * XStringToKeysym() and XKeysymToString().
- *
- * Where a keysym corresponds one-to-one to an ISO 10646 / Unicode
- * character, this is noted in a comment that provides both the U+xxxx
- * Unicode position, as well as the official Unicode name of the
- * character.
- *
- * Where the correspondence is either not one-to-one or semantically
- * unclear, the Unicode position and name are enclosed in
- * parentheses. Such legacy keysyms should be considered deprecated
- * and are not recommended for use in future keyboard mappings.
- *
- * For any future extension of the keysyms with characters already
- * found in ISO 10646 / Unicode, the following algorithm shall be
- * used. The new keysym code position will simply be the character's
- * Unicode number plus 0x01000000. The keysym values in the range
- * 0x01000100 to 0x0110ffff are reserved to represent Unicode
- * characters in the range U+0100 to U+10FFFF.
- * 
- * While most newer Unicode-based X11 clients do already accept
- * Unicode-mapped keysyms in the range 0x01000100 to 0x0110ffff, it
- * will remain necessary for clients -- in the interest of
- * compatibility with existing servers -- to also understand the
- * existing legacy keysym values in the range 0x0100 to 0x20ff.
- *
- * Where several mnemonic names are defined for the same keysym in this
- * file, all but the first one listed should be considered deprecated.
- *
- * Mnemonic names for keysyms are defined in this file with lines
- * that match one of these Perl regular expressions:
- *

- * Before adding new keysyms, please do consider the following: In
- * addition to the keysym names defined in this file, the
- * XStringToKeysym() and XKeysymToString() functions will also handle
- * any keysym string of the form "U0020" to "U007E" and "U00A0" to
- * "U10FFFF" for all possible Unicode characters. In other words,
- * every possible Unicode character has already a keysym string
- * defined algorithmically, even if it is not listed here. Therefore,
- * defining an additional keysym macro is only necessary where a
- * non-hexadecimal mnemonic name is needed, or where the new keysym
- * does not represent any existing Unicode character.
- *
- * When adding new keysyms to this file, do not forget to also update the
- * following as needed:
- *
- *   - the mappings in src/KeyBind.c in the repo
- *     git://anongit.freedesktop.org/xorg/lib/libX11.git
- *
- *   - the protocol specification in specs/keysyms.xml
- *     in the repo git://anongit.freedesktop.org/xorg/proto/x11proto.git

- * generates the symbol 'A'.  If a different layout is used, say Greek,
- * it generates the symbol 'α'.  And so on.
- *
- * Each such symbol is represented by a keysym.  Note that keysyms are

-/**
- * Test whether a modifier is consumed by keyboard state translation for
- * a key.
- *
- * Some functions, like xkb_state_key_get_syms(), look at the state of
- * the modifiers in the keymap and derive from it the correct shift level
- * to use for the key.  For example, in a US layout, pressing the key
- * labeled \<A\> while the Shift modifier is active, generates the keysym 'A'.
- * In this case, the Shift modifier is said to be consumed.  However, the
- * Num Lock modifier does not affect this translation at all, even if it
- * active, so it is not consumed by this translation.
- *
- * It may be desirable for some application to not reuse consumed modifiers
- * for further processing, e.g. for hotkeys or keyboard shortcuts. To
- * understand why, consider some requirements from a standard shortcut
- * mechanism, and how they are implemented:
- *
- * 1. The shortcut's modifiers must match exactly to the state. For example,
- *    it is possible to bind separate actions to \<Alt\>\<Tab\> and to
- *    \<Alt\>\<Shift\>\<Tab\>. Further, if only \<Alt\>\<Tab\> is bound to
- *    an action, pressing \<Alt\>\<Shift\>\<Tab\> should not trigger the
- *    shortcut.
- *    Effectively, this means that the modifiers are compared using the
- *    equality operator (==).
- * 2. Only relevant modifiers are considered for the matching. For example,
- *    Caps Lock and Num Lock should not generally affect the matching, e.g.
- *    when matching \<Alt\>\<Tab\> against the state, it does not matter
- *    whether Num Lock is active or not. These relevant, or significant,
- *    modifiers usually include Alt, Control, Shift, Super and similar.
- *    Effectively, this means that non-significant modifiers are masked out,
- *    before doing the comparison as described above.
- * 3. The matching must be independent of the layout/keymap. For example,
- *    the \<Plus\> (+) symbol is found on the first level on some layouts,
- *    and requires holding Shift on others. If you simply bind the action
- *    to the \<Plus\> keysym, it would work for the unshifted kind, but
- *    not for the others, because the match against Shift would fail. If
- *    you bind the action to \<Shift\>\<Plus\>, only the shifted kind would
- *    work. So what is needed is to recognize that Shift is used up in the
- *    translation of the keysym itself, and therefore should not be included
- *    in the matching.
- *    Effectively, this means that consumed modifiers (Shift in this example)
- *    are masked out as well, before doing the comparison.
- *
- * To summarize, this is how the matching would be performed:
- * @code
- *   (keysym == shortcut_keysym) &&
- *   ((state_modifiers & ~consumed_modifiers & significant_modifiers) == shortcut_modifiers)
- * @endcode
- *
- * @c state_modifiers are the modifiers reported by
- * xkb_state_mod_index_is_active() and similar functions.
- * @c consumed_modifiers are the modifiers reported by
- * xkb_state_mod_index_is_consumed().
- * @c significant_modifiers are decided upon by the application/toolkit/user;
- * it is up to them to decide whether these are configurable or hard-coded.
- *
- * @returns 1 if the modifier is consumed, 0 if it is not.  If the modifier
- * index is not valid in the keymap, returns -1.

+Subject: [PATCH 1/8] ANGLE: Use pixel sizes in the XAML swap chain
+
+This is necessary for Qt applications, as they render to GL in physical
+pixels. This is consistent with the CoreWindow swap chain behavior.
+
+In order to achieve proper scaling, the scale factor has to be initialized
+properly in InspectableNativeWindow.
+
+This change only affects Windows Runtime targets.

-Subject: [PATCH 4/7] ANGLE: Allow Windows Phone to communicate swap region
-
-eglPostSubBufferNV is used to communicate the size of the window, as
-otherwise there is no way for the renderer to know if the last frame was
-rendered in landscape or portrait, causing rendering glitches when the
-orientation changes. The rotation flags are utilized in a few additional
-places now to fix some corner cases where the rotation was not applied.
-
-This patch should be squashed into "ANGLE-Improve-Windows-Phone-Support"
-during the next ANGLE rebase.

-
-This is necessary for Qt applications, as they render to GL in physical
-pixels. This is consistent with the CoreWindow swap chain behavior.
-
-This includes a partial revert of "ANGLE: Improve Windows Phone Support"
-as the modifications to SwapChain11 are incompatible with the XAML swap

+Subject: [PATCH] Revert "Fix scanForWantedComponents not ignoring
+ attribute values of 0."
+
+This patch reverts commit 2648d9297f25a0d1fa2837f020975a45d4e8a8b9 as a
+workaround for the "banding" artifacts we were seeing in Qt. Angle
+returns a list of supported graphic formats or configurations, sorting
+it in a way that the first one should be the one that fits better the
+requested format. In Qt we use the first thing we receive in the list.
+In the current Angle version, however, a fix has changed the way in
+which the list is sorted. In the old version the first element would be
+a 32-bit graphic format, while now it's a 16-bit one, resulting in the
+"banding" artifacts. The workaround reverts back to the previous sorting
+behavior.

+Subject: [PATCH] ANGLE: Disable multisampling to avoid crash in Qt
+ applications
+
+This patch adds a workaround for the crash that occurs with multisampling
+enabled in some Qt applications (e.g., the 2dpainting example). The old
+Angle release we were using lacked support for multisampling, so it was
+ignored when requested. This current version seems to support it, but is
+causing a crash in the D3D11 shaders, so this workaround disables that
+support.

+Subject: [PATCH] ANGLE: Dynamically load D3D compiler from a list
 
 If the default compiler cannot be found, load it from a list of DLL names,
 including a non-versioned proxy DLL provided by Qt. On Desktop Windows,
 the default compiler can also be specified by an environment variable,
 QT_D3DCOMPILER_DLL.

-
-Release builds of applications that used Qt configured with "link time
-code generation" crashed (memory access violation), when calling
-GetInternalFormatInfo in Context::initCaps.
-
-It looks like this is a compiler problem that can be avoided by not
-using a reference for the return value.

-    The \l QDataStream allows you to serialize some of the Qt data types.
-    The table below lists the data types that QDataStream can serialize
-    and how they are represented. The format described below is
-    \l{QDataStream::setVersion()}{version 13}.
+    The \l QDataStream class allows you to serialize the Qt data types
+    listed in this section as of \l{QDataStream::setVersion()}{version 18}.
 
     It is always best to cast integers to a Qt integer type, such as
-    qint16 or quint32, when reading and writing. This ensures that
+    \l{qint16} or \l{quint32}, when reading and writing. This ensures that
     you always know exactly what size integers you are reading and
     writing, no matter what the underlying platform and architecture
     the application happens to be running on.

     \section1 Compression
 
-    Resources are compressed by default (in the \c ZIP format). It is
-    possible to turn off compression. This can be useful if your
-    resources already contain a compressed format, such as \c .png
-    files. You do this by giving the \c {-no-compress} command line
-    argument.
+    \c rcc attempts to compress the content to optimize disk space usage in the
+    final binaries. By default, it will perform a heuristic check to determine
+    whether compressing is worth it and will store the content uncompressed if
+    it fails to sufficiently compress. To control the threshold, you can use
+    the \c {-threshold} option, which tells \c rcc the percentage of the
+    original file size that must be gained for it to store the file in
+    compressed form.
+
+    \code
+        rcc -threshold 25 myresources.qrc
+    \endcode
+
+    The default value is "70", indicating that the compressed file must be 70%
+    smaller than the original (no more than 30% of the original file size).
+
+    It is possible to turn off compression, if desired. This can be useful if
+    your resources already contain a compressed format, such as \c .png files,
+    and you do not want to incur the CPU cost at build time to confirm that it
+    can't be compressed. Another reason is if disk usage is not a problem and
+    the application would prefer to keep the content as clean memory pages at
+    runtime. You do this by giving the \c {-no-compress} command line argument.
 
     \code
         rcc -no-compress myresources.qrc
     \endcode
 
-    \c rcc also gives you some control over the compression. You can
-    specify the compression level and the threshold level to consider
-    while compressing files, for example:
+    \c rcc also gives you some control over the compression level and
+    compression algorithm, for example:
 
     \code
-        rcc -compress 2 -threshold 3 myresources.qrc
+        rcc -compress 2 -compress-algo zlib myresources.qrc
     \endcode
 
+    \c rcc supports the following compression algorithms and compression
+    levels:
+
+    \list
+      \li \c{best}: use the best algorithm among the ones below, at its highest
+      compression level, to achieve the most compression at the expense of
+      using a lot of CPU time during compilation. This value is useful in the
+      XML file to indicate a file should be most compressed, regardless of
+      which algorithms \c rcc supports.
+
+      \li \c{zstd}: use the \l{Zstandard}{https://zstd.net} library to compress
+      contents. Valid compression levels range from 1 to 19, 1 is least
+      compression (least CPU time) and 19 is the most compression (most CPU
+      time). The default level is 14. A special value of 0 tells the \c{zstd}
+      library to choose an implementation-defined default.
+
+      \li \c{zlib}: use the \l{zlib}{https://zlib.net} library to compress
+      contents. Valid compression levels range from 1 to 9, with 1the least
+      compression (least CPU time) and 9 the most compression (most CPU time).
+      The special value 0 means "no compression" and should not be used. The
+      default is implementation-defined, but usually is level 6.
+
+      \li \c{none}: no compression. This is the same as the \c{-no-compress}
+      option.
+    \endlist
+
+    Support for both Zstandard and zlib are optional. If a given library was
+    not detected at compile time, attempting to pass \c {-compress-algo} for
+    that library will result in an error. The default compression algorithm is
+    \c zstd if it is enabled, \c zlib if not.

     The files to be selected are placed in directories named with a \c'+' and a selector name. In the above
     example you could have the platform configurations selected by placing them in the following locations:
-    \code
-    data/defaults.conf

-    \endcode

     To find selected files, QFileSelector looks in the same directory as the base file. If there are
     any directories of the form +<selector> with an active selector, QFileSelector will prefer a file
     with the same file name from that directory over the base file. These directories can be nested to
     check against multiple selectors, for example:

     In the first line in snippet above, a file URL is constructed from a
     local, relative path. A file URL with a relative path only makes sense
     if there is a base URL to resolve it against. For example:
 
-    \code
-    QUrl url = QUrl::fromLocalFile("file.txt");
-    QUrl baseUrl = QUrl("file:/home/user/");
-    // wrong: prints QUrl("file:file.txt"), as url already has a scheme
-    qDebug() << baseUrl.resolved(url);
-    \endcode
+    \snippet code/src_corelib_io_qurl.cpp 17
 
     To resolve such a URL, it's necessary to remove the scheme beforehand:
 
-    \code
-    // correct: prints QUrl("file:///home/user/file.txt")
-    url.setScheme(QString());
-    qDebug() << baseUrl.resolved(url);
-    \endcode
+    \snippet code/src_corelib_io_qurl.cpp 18
 
     For this reason, it is better to use a relative URL (that is, no scheme)
     for relative file paths:
 
-    \code
-    QUrl url = QUrl("file.txt");
-    QUrl baseUrl = QUrl("file:/home/user/");
-    // prints QUrl("file:///home/user/file.txt")

     Applications which want to define custom MIME types need to install an
     XML file into the locations searched for MIME definitions.
     These locations can be queried with
-    \code
-    QStandardPaths::locateAll(QStandardPaths::GenericDataLocation, QLatin1String("mime/packages"),

     On a typical Unix system, this will be /usr/share/mime/packages/, but it is also
     possible to extend the list of directories by setting the environment variable
     \c XDG_DATA_DIRS. For instance adding /opt/myapp/share to \c XDG_DATA_DIRS will result
     in /opt/myapp/share/mime/packages/ being searched for MIME definitions.
 
     Here is an example of MIME XML:
-    \code
-    <?xml version="1.0" encoding="UTF-8"?>
-    <mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">

-  This function updates an internal state to keep the source compatibility. Documentation of
-  QGuiApplication::mouseButtons() states - "The current state is updated synchronously as
-  the event queue is emptied of events that will spontaneously change the mouse state
-  (QEvent::MouseButtonPress and QEvent::MouseButtonRelease events)". But internally we have
-  been updating these state variables from various places to keep buttons returned by
-  mouseButtons() in sync with the systems state. This is not the documented behavior.
-
-  ### Qt6 - Remove QGuiApplication::mouseButtons()/keyboardModifiers() API? And here
-  are the reasons:
-
-  - It is an easy to misuse API by:
-
-   a) Application developers: The only place where the values of this API can be trusted is
-      when using within mouse handling callbacks. In these callbacks we work with the state
-      that was provided directly by the windowing system. Anywhere else it might not reflect what
-      user wrongly expects. We might not always receive a matching mouse release for a press event
-      (e.g. When dismissing a popup window on X11. Or when dnd enter Qt application with mouse
-      button down, we update mouse_buttons and then dnd leaves Qt application and does a drop
-      somewhere else) and hence mouseButtons() will be out-of-sync from users perspective, see
-      for example QTBUG-33161. BUT THIS IS NOT HOW THE API IS SUPPOSED TO BE USED. Since the only
-      safe place to use this API is from mouse event handlers, we might as well deprecate it and
-      pass down the button state if we are not already doing that everywhere where it matters.
-
-   b) Qt framework developers:
-
-      We see users complaining, we start adding hacks everywhere just to keep buttons in sync ;)
-      There are corner cases that can not be solved and adding this kind of hacks is never ending
-      task.
-
-  - Real mouse events, tablet mouse events, etc: all go through QGuiApplication::processMouseEvent,
-    and all share mouse_buttons. What if we want to support multiple mice in future? The API must
-    go.
-
-  - Motivation why this API is public is not clear. Could the same be achieved by a user by
-    installing an event filter?
+  This function updates an internal state to keep the source compatibility.

+    \class QColorSpace
+    \brief The QColorSpace class provides a color space abstraction.
+    \since 5.14
+
+    \ingroup painting
+    \ingroup appearance
+    \inmodule QtGui
+
+    Color values can be interpreted in different ways, and based on the interpretation
+    can live in different spaces. We call this \e {color spaces}.
+
+    QColorSpace provides access to creating several predefined color spaces and
+    can generate QColorTransforms for converting colors from one color space to
+    another.
+
+    QColorSpace can also represent color spaces defined by ICC profiles or embedded
+    in images, that do not otherwise fit the predefined color spaces.
+
+    A color space can generally speaking be conceived as a combination of a transfer
+    function and a gamut. The gamut defines which colors the color space can represent.
+    A color space that can represent a wider range of colors is also known as a
+    wide-gamut color space. The gamut is defined by three primary colors that represent
+    exactly how red, green, and blue look in this particular color space, and a white
+    color that represents where and how bright pure white is.
+
+    The transfer function or gamma curve determines how each component in the
+    color space is encoded. These are used because human perception does not operate
+    linearly, and the transfer functions try to ensure that colors will seem evenly
+    spaced to human eyes.

+    QColorTransform is an instantiation of a transformation between color spaces.
+    It can be applied on color and pixels to convert them from one color space to

+

+    QColorTransforms that you need often is recommended, instead of generating

+    - Transmitting intermediate certificates
+        - Look for a way to avoid putting intermediate certificates in the certificate store
+        - No documentation on how to send the chain
+        - A stackoverflow question on this from 3 years ago implies schannel only sends intermediate
+            certificates if it's "in the system or user certificate store".
+                - https://stackoverflow.com/q/30156584/2493610
+                - This can be done by users, but we shouldn't add any and all local intermediate
+                    certs to the stores automatically.
+    - PSK support
+        - Was added in Windows 10 (it seems), documentation at time of writing is sparse/non-existent.
+            - Specifically about how to supply credentials when they're requested.
+            - Or how to recognize that they're requested in the first place.
+        - Skip certificate verification.
+        - Check if "PSK-only" is still required to do PSK _at all_ (all-around bad solution).
+        - Check if SEC_I_INCOMPLETE_CREDENTIALS is still returned for both "missing certificate" and
+            "missing PSK" when calling InitializeSecurityContext in "performHandshake".
+
+    Medium priority:
+    - Setting cipher-suites (or ALG_ID)

+    Apple has gone through many iterations of its font smoothing algorithms,
+    and there are many ways to enable or disable certain aspects of it. As
+    keeping up with all the different toggles and behavior differences between
+    macOS versions is tricky, we resort to rendering a single glyph in a few
+    configurations, picking up the font smoothing algorithm from the observed
+    result.
+
+    The possible values are:
+
+     - Disabled: No font smoothing is applied.
+
+       Possibly triggered by the user unchecking the "Use font smoothing when
+       available" checkbox in the system preferences or setting AppleFontSmoothing
+       to 0. Also controlled by the CGContextSetAllowsFontSmoothing() API,
+       which gets its default from the settings above. This API overrides
+       the more granular CGContextSetShouldSmoothFonts(), which we use to
+       enable (request) or disable font smoothing.
+
+       Note that this does not exclude normal antialiasing, controlled by
+       the CGContextSetShouldAntialias() API.
+
+     - Subpixel: Font smoothing is applied, and affects subpixels.
+
+       This was the default mode on macOS versions prior to 10.14 (Mojave).
+       The font dilation (stem darkening) parameters were controlled by the
+       AppleFontSmoothing setting, ranging from 1 to 3 (light to strong).
+
+       On Mojave it is no longer supported, but can be triggered by a legacy
+       override (CGFontRenderingFontSmoothingDisabled=NO), so we need to
+       still account for it, otherwise users will have a bad time.
+
+     - Grayscale: Font smoothing is applied, but does not affect subpixels.

+       setting, but are instead computed based on the fill color used when
+       drawing the glyphs (white fill gives a lighter dilation than black
+       fill). This affects how we build our glyph cache, since we produce
+       alpha maps by drawing white on black.

-    In short on how and why the "Compose" file is cached:
-
-    The "Compose" file is large, for en_US it's likely located at:
-    /usr/share/X11/locale/en_US.UTF-8/Compose
-    and it has about 6000 string lines.
-    Q(Gui)Applications parse this file each time they're created. On modern CPUs
-    it incurs a 4-10 ms startup penalty of each Qt gui app, on older CPUs -
-    tens of ms or more.
-    Since the "Compose" file (almost) never changes using a pre-parsed
-    cache file instead of the "Compose" file is a good idea to improve Qt5
-    application startup time by about 5+ ms (or tens of ms on older CPUs).
-
-    The cache file contains the contents of the QComposeCacheFileHeader struct at the
-    beginning followed by the pre-parsed contents of the "Compose" file.
-
-    struct QComposeCacheFileHeader stores
-    (a) The cache version - in the unlikely event that some day one might need
-    to break compatibility.
-    (b) The (cache) file size.
-    (c) The lastModified field tracks if anything changed since the last time
-    the cache file was saved.
-    If anything did change then we read the compose file and save (cache) it
-    in binary/pre-parsed format, which should happen extremely rarely if at all.

+    The reason for using this helper is to ensure that QNSView doesn't implement
+    the NSResponder callbacks for mouseEntered, mouseExited, and mouseMoved.
+
+    If it did, we would get mouse events though the responder chain as well,
+    for example if a subview has a tracking area of its own and calls super
+    in the handler, which results in forwarding the event though the responder
+    chain. The same applies if NSWindow.acceptsMouseMovedEvents is YES.
+
+    By having a helper as the target for our tracking areas, we know for sure
+    that the events we are getting stem from our own tracking areas.
+
+    FIXME: Ideally we wouldn't need this workaround, and would correctly
+    interact with the responder chain by e.g. calling super if Qt does not
+    accept the mouse event

+    \class QXcbEventQueue
+    \internal
+
+    Lock-free event passing:
+
+    The lock-free solution uses a singly-linked list to pass events from the
+    reader thread to the main thread. An atomic operation is used to sync the
+    tail node of the list between threads. The reader thread takes special care
+    when accessing the tail node. It does not dequeue the last node and does not
+    access (read or write) the tail node's 'next' member. This lets the reader
+    add more items at the same time as the main thread is dequeuing nodes from
+    the head. A custom linked list implementation is used, because QLinkedList
+    does not have any thread-safety guarantees and the custom list is more
+    lightweight - no reference counting, back links, etc.
+
+    Memory management:
+
+    In a normally functioning application, XCB plugin won't buffer more than few
+    batches of events, couple events per batch. Instead of constantly calling
+    new / delete, we can create a pool of nodes that we reuse. The main thread
+    uses an atomic operation to sync how many nodes have been restored (available
+    for reuse). If at some point a user application will block the main thread
+    for a long time, we might run out of nodes in the pool. Then we create nodes
+    on a heap. These will be automatically "garbage collected" out of the linked
+    list, once the main thread stops blocking.

     multibyte enabled PostgreSQL server can be found in the PostgreSQL

+    \section3 QPSQL Case Sensitivity
+
+    PostgreSQL databases will only respect case sensitivity if the table or field
+    name is quoted when the table is created. So for example, a SQL query such
+    as:
+
+    \snippet code/doc_src_sql-driver.qdoc 39
+
+    will ensure that it can be accessed with the same case that was used. If the
+    table or field name is not quoted when created, the actual table name
+    or field name will be lower-case. When QSqlDatabase::record() or
+    QSqlDatabase::primaryIndex() access a table or field that was unquoted
+    when created, the name passed to the function must be lower-case to
+    ensure it is found. For example:
+
+    \snippet code/doc_src_sql-driver.qdoc 40
