Remove Infinality as an option before its complete extraction.
* include/freetype/ftoption.h: Remove the Infinality option.
* devel/ftoption.h: Ditto.
* include/freetype/ftdriver.h (TT_INTERPRETER_VERSION_38): Is 40 now.
This is mandated by the C99 standard, and clang 15 produces zillions of
warnings otherwise.
* devel/ftoption.h, include/freetype/config/ftoption.h,
include/freetype/internal/ftmemory.h, src/autofit/afhints.h,
src/autofit/afmodule.c, src/autofit/aftypes.h, src/base/ftadvanc.c,
src/base/ftdbgmem.c, src/base/ftstream.c, src/bdf/bdflib.c,
src/truetype/ttinterp.c: Replace identifiers of the form `_foo` with `foo_`.
This gives users a possibility to deactivate new features not (yet) in the
OpenType standard.
* include/freetype/config/ftoption.h, devel/ftoption.h
(TT_CONFIG_OPTION_NO_BORING_EXPANSION): New macro.
* src/truetype/ttgxvar.c (ft_var_load_avar): Use it to disable 'avar'
version 2.0 support.
This flag is going to be used to conditionally compile support for OT-SVG
glyphs. FreeType will do the parsing and rely on external hooks for
rendering of OT-SVG glyphs.
* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_SVG): New flag.
This feature was always experimental, and probably nevery worked
properly. This patch completely removes it from the source code,
except for a documentation block describing it for historical
purpose.
* autogen.sh (copy_submodule_files): New script to copy all the
necessary source and include files from `submodules/dlg` to
`src/dlg`.
* src/dlg/dlgwrap.c: New wrapper file for `src/dlg.c`. It enables
the build of 'dlg' if the `FT_LOGGING` macro is defined.
* src/dlg/rules.mk: New sub-Makefile.
* builds/freetype.mk (DLG_DIR): New variable to include the
header files of the 'dlg' library.
(INCLUDES): Add `DLG_DIR`.
(FT_CFLAGS): Add `-std=c99' flag.
Include `src/dlg/rules.mk` file to build 'dlg' library.
(OBJ_S, OBJ_M): Add `DLG_OBJS_M` and `DLG_OBJS_S`.
* builds/toplevel.mk: For builds directly from the git repository
we need to copy files from `submodule/dlg` to `src/dlg`.
* include/freetype/config/ftoption.h, devel/ftoption.h (FT_LOGGING):
New macro to enable or disable the logging facility in FreeType.
These have not been used in a very, very long time, so better remove
them. A corresponding patch will be submitted to the
`freetype2-demos' repository.
* src/Jamfile, src/*/Jamfile, Jamrules: Delete.
Brotli is required for decompressing WOFF2 font directory streams.
The library is thus being added as an optional dependency for
FreeType.
* builds/unix/configure.raw: Add checks for `libbrotlidec'.
(REQUIRES_PRIVATE, LIBS_PRIVATE, LIBSSTATIC_CONFIG): Updated.
* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_USE_BROTLI): New macro.
This second and final monster commit was created by applying Nikhil's
scripts `docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.
No change in functionality, of course.
I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.
This commit enables OpenType's COLR/CPAL table handling; a typical
application are color emojis that can be scaled to any size.
If the color palette does not exist or is invalid, the rendering
step rasterizes the outline instead. The current implementation
assumes that the foreground is black.
Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.
There are still some issues with metrics; additionally, an API to
fetch color layers is missing.
* devel/ftoption.h, include/freetype/config/ftoption.h
(TT_CONFIG_OPTION_COLOR_LAYERS): New macro.
* include/freetype/internal/ftobjs.h (FT_Glyph_LayerRec,
FT_Colr_InternalRec): New structures.
(FT_Slot_InternalRec): Add `color_layers' field.
* include/freetype/internal/sfnt.h (TT_Load_Colr_Layer_Func,
TT_Blend_Colr_Func): New function types.
(SFNT_Interface): Add `load_colr', `free_colr', `load_colr_layer',
and `colr_blend' fields.
* include/freetype/internal/tttypes.h (TT_FaceRec): Add
`colr_and_cpal' field.
* include/freetype/internal/tttags. (TTAG_COLR, TTAG_CPAL): New
macros.
* src/sfnt/ttcolr.c, src/sfnt/ttcolr.h: New files.
* src/base/ftobjs.c (ft_glyphslot_done, FT_Render_Glyph_Internal):
Handle glyph color layers.
* src/sfnt/Jamfile (_sources), src/sfnt/rules.mk (SFNT_DRV_SRC): Add
`ttcolr.c'.
* src/sfnt/sfdriver.c: Include `ttcolr.h'.
(PUT_COLOR_LAYERS): New macro.
Update call to `FT_DEFINE_SFNT_INTERFACE'.
* src/sfnt/sfnt.c: Include `ttcolr.c'.
* src/sfnt/sfobjs.c (sfnt_load_face): Load `COLR' and `CPAL' tables.
(sfnt_done_face): Updated.
* src/truetype/ttgload.c (TT_Load_Glyph): Handle color layers.
*/* [FT_CONFIG_OPTION_PIC]: Remove all code guarded by this
preprocessor symbol.
*/*: Replace `XXX_GET' macros (which could be either a function in
PIC mode or an array in non-PIC mode) with `xxx' arrays.
* include/freetype/internal/ftpic.h, src/autofit/afpic.c,
src/autofit/afpic.h, src/base/basepic.c, src/base/basepic.h,
src/base/ftpic.c, src/cff/cffpic.c, src/cff/cffpic.h,

src/smooth/ftspic.h, src/truetype/ttpic.c, src/truetype/ttpic.h:
Removed.
This controls whether the old Type 1 engine gets compiled into FreeType.
It is disabled by default.
* devel/ftoption.h, include/freetype/config/ftoption.h
(T1_CONFIG_OPTION_OLD_ENGINE): New macro.
* include/freetype/internal/psaux.h (PS_Decoder): Remove unused field.
* include/freetype/internal/psaux.h, src/cid/cidgload.c
(cid_load_glyph), src/psaux/psauxmod.c, src/psaux/psobjs.c
(ps_builder_add_point), src/psaux/t1decode.c

t1operator_seac, t1_decoder_parse_charstrings), src/psaux/t1decode.h,
src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Surround
relevant code with macro.
Minor code changes.
* build/windows/vc2010/freetype.vcxproj: Use DynamicLibrary in Debug
and Release configurations.
* include/freetype/config/ftconfig.h (FT_EXPORT, FT_EXPORT_DEF)
[_DLL]: Use Visual C++ extensions.
This is a new technology for LCD-optimized rendering. It capitalizes
on the fact that each color channel grid is shifted by a third of a
pixel. Therefore it is logical to render 3 separate monochrome
bitmaps shifting the outline by 1/3 pixel, and then combine them.
Importantly, the resulting output does not require additional LCD
filtering.
* src/smooth/ftsmooth.c (ft_smooth_render_generic)
[!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized
rendering.
* include/freetype/ftlcdfil.h, include/freetype/freetype.h,
include/freetype/config/ftoption.h, devel/ftoption.h: Updated
documentation.
The change from 2016-09-29 was too radical (except for people using
the openSuSE GNU/Linux distribution). To ameliorate the situation,
PCF_CONFIG_OPTION_LONG_FAMILY_NAMES gets introduced which controls
the feature; if set, a new PCF property option
`no-long-family-names' can be used to switch this feature off.
* include/freetype/config/ftoption.h, devel/ftoption.h
(PCF_CONFIG_OPTION_LONG_FAMILY_NAMES): New option.
* include/freetype/ftpcfdrv.h: New header file (only containing
comments currently, used for building the documentation).
* include/freetype/config/ftheader.h (FT_PCF_DRIVER_H): New macro.
* src/pcf/pcf.h (PCF_Driver): Add `no_long_family_names' field.
* src/pcf/pcfdrivr.c: Include FT_SERVICE_PROPERTIES_H and
FT_PCF_DRIVER_H.
(pcf_property_set, pcf_property_get): New functions.
(pcf_service_properties): New service.
(pcf_servives): Updated.
(pcf_driver_init) [PCF_CONFIG_OPTION_LONG_FAMILY_NAMES]: Handle
`no_long_family_names'.
* src/pcf/pcfread.c (pcf_load_font): Handle `no_long_family_names'
and PCF_CONFIG_OPTION_LONG_FAMILY_NAMES.
* docs/CHANGES: Updated.
Recognizing properties follows in another commit.
* devel/ftoption.h, include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES): New macro.
* include/freetype/config/ftstdlib.h (ft_getenv): New macro.
* src/base/ftinit.c (ft_set_default_properties): New function to
parse `FREETYPE_PROPERTIES' and calling `ft_property_string_set'.
(FT_Init_FreeType): Updated.
