We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.
*/*: Replace
#include FOO_H
with
#include <freetype/foo.h>
or something similar. Also update the documentation.
* src/sfnt/sfdriver (IS_WIN, IS_APPLE): Omit language ID checks.
(get_win_string, get_apple_string): Return NULL when the PostScript
font name characters is not according to specification.
(get_win_string): Make trace output work if the high byte if
non-zero.
(sfnt_get_var_ps_name, sfnt_get_ps_name): Previously we preferred
Win PS name (when there is also an Apple PS name); change this into
a fallback to Apple PS name in case the Win PS name is invalid.
This solution doesn't store any data in an `FT_GlyphSlot' object.
* include/freetype/freetype.h (FT_LayerIterator): New structure.
(FT_Get_Color_Glyph_Layer): New function.
* include/freetype/internal/sfnt.h (TT_Get_Colr_Layer_Func): New
function type.
(SFNT_Interface, FT_DEFINE_SFNT_INTERFACE): Add it.

* src/sfnt/ttcolr.c (tt_face_get_colr_layer): New function.
* src/sfnt/ttcolr.h: Updated.
* src/sfnt/sfdriver.c (sfnt_interface): Updated.
* src/sfnt/sfdriver.c: Include `ttcpal.h'.

* src/sfnt/ttcolr.c, src/sfnt/ttcolr.h: Move CPAL stuff to ...
* src/sfnt/ttcpal.c, src/sfnt/ttcpal.c: ... these new files.
* src/sfnt/Jamfile (_sources), src/sfnt/rules.mk (SFNT_DRV_SRC):
Updated.
* include/freetype/internal/fttrace.h: Add support for `colr' and
`cpal'.
Sort entries.
* src/sfnt/ttcolr.c (tt_face_palette_set): New function.
(tt_face_load_colr): Allocate `face->palette' and call
`tt_face_palette_set'.
Adjust return error code in case of error.
* src/sfnt/ttcolr.h: Updated.
* include/freetype/internal/sfnt.h (TT_Set_Palette_Func): New
function type.
(SFNT_Interface, FT_DEFINE_SFNT_INTERFACE): Add it.
* src/sfnt/sfdriver.c (sfnt_interface), src/sfnt/sfobjs.c
(sfnt_done_face): Updated.
This 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.
