+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:
+ * 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'.
+ *

+ * @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.

+ * The TrueType driver
+ *
+ * @abstract:
+ * Controlling the TrueType driver module.
+ *
+ * @description:
+ * While FreeType's TrueType driver doesn't expose API functions by
+ * itself, it is possible to control its behaviour with @FT_Property_Set
+ * and @FT_Property_Get. The following lists the available properties
+ * together with the necessary macros and structures.
+ *
+ * The TrueType driver's module name is `truetype'.
+ *
+ * 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.

+ * 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

+ * counteracts the `thinning out' of glyphs, making text remain readable
+ * at smaller sizes.

+ * 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

+ * Color and Gray ClearType are the two available variants of
+ * `Y-direction ClearType', meaning grayscale rasterization along the
+ * 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.

+ *
+ * @description:
+ * Currently, three versions are available, two representing the
+ * bytecode interpreter with subpixel hinting support (old `Infinality'
+ * code and new stripped-down and higher performance `minimal' code) and
+ * one without, respectively. The default is subpixel support if
+ * TT_CONFIG_OPTION_SUBPIXEL_HINTING is defined, and no subpixel support
+ * otherwise (since it isn't available then).
+ *
+ * If subpixel hinting is on, many TrueType bytecode instructions behave
+ * differently compared to B/W or grayscale rendering (except if `native
+ * ClearType' is selected by the font). Microsoft's main idea is to
+ * render at a much increased horizontal resolution, then sampling down
+ * the created output to subpixel precision. However, many older fonts
+ * are not suited to this and must be specially taken care of by
+ * applying (hardcoded) tweaks in Microsoft's interpreter.
+ *
+ * Details on subpixel hinting and some of the necessary tweaks can be
+ * found in Greg Hitchcock's whitepaper at
+ * `https://www.microsoft.com/typography/cleartype/truetypecleartype.aspx'.
+ * Note that FreeType currently doesn't really `subpixel hint' (6x1, 6x2,
+ * or 6x5 supersampling) like discussed in the paper. Depending on the
+ * chosen interpreter, it simply ignores instructions on vertical stems
+ * to arrive at very similar results.
+ *
+ * The following example code demonstrates how to deactivate subpixel
+ * hinting (omitting the error handling).

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

* 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.
