* src/base/ftcalc.c (FT_Matrix_Check): New base function to properly
reject degenerate font matrices.
* include/freetype/internal/ftcalc.h: Updated.
* src/cff/cffparse.c (cff_parse_font_matrix), src/cid/cidload.c
(cid_parse_font_matrix), src/type1/t1load.c (t1_parse_font_matrix),
src/type42/t42parse.c (t42_parse_font_matrix): Use
`FT_Matrix_Check'.
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.
*/* [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.

Removed.
For functions querying a face, bits 16-30 of the face index can hold
the named instance index if we have a GX font. The indices start
with value 1; value 0 indicates font access without GX variation
data.
* include/freetype/freetype.h (FT_FaceRec): Update documentation.
* include/freetype/internal/sfnt.h: Ditto.
* src/sfnt/sfobjs.c (sfnt_init_face)
[TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Get number of named instances and
do argument checks.
(sfnt_load_face): Updated.
* src/truetype/ttobjs.c (tt_face_init)
[TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Use named instance, overwriting
the style name.
* src/base/ftobjs.c (open_face_from_buffer,
open_face_PS_from_sfnt_stream): Updated.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Updated.
* src/cff/cffload.c (cff_font_load): Updated.
* src/cff/cffobjs.c (cff_face_init): Make function exit early for
pure CFF fonts if `font_index < 0'.
Updated.
* src/cid/cidobjs.c (cid_face_init): Updated.
* src/pcf/pcfdrivr.c (PCF_Face_Init): Updated.
* src/pfr/pfrobjs.c (pfr_face_init): Updated.
* src/type1/t1objs.c (T1_Face_Init): Updated.
* src/type42/t42objs.c (T42_Face_Init): Updated.
* src/winfonts/winfnt.c (fnt_face_get_dll_font, FNT_Face_Init):
Updated.
* docs/CHANGES: Updated.
* src/type1/t1load.c (t1_parse_font_matrix): Scale units per EM only
when necessary. Refresh comments.
* src/cid/cidload.c (cid_parse_font_matrix): Ditto.
* src/type42/t42parse.c (t42_parse_font_matrix): Refresh comments.
This is a severe bug: We've missed one level of indirection, as
described in the Type 42 specification. As a result, ftview
sometimes showed incorrect glyphs for given glyph names, and even
displayed `error 0x0006' (invalid argument!) in case the number of
glyph indices differed between the Type 42 font and the embedded
TTF.
Apparently, noone ever noticed it; this shows how much Type 42 fonts
are in use...
* src/type42/t42objs.c (T42_GlyphSlot_Load): Map Type 42 glyph index
to embedded TTF's glyph index.
This is just very basic stuff and just a little bit tested on
GNU/Linux only. I won't delve into this since I'm not a Jam user.
* Jamfile: Call `HDRMACRO' for `ftserv.h' also.
(DEFINES): Replace with...
(CCFLAGS): ... this.
* src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is
already handled in the top-level Jamfile.
* src/autofit/Jamfile (DEFINES): Replace with...
(CCFLAGS): ... this.
(_sources): Add missing files.
* src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no
longer contains macro header definitions.
* src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile,
src/truetype/Jamfile (_sources): Add missing files.
Assure that FreeType's internal include directories are found before
`CPPFLAGS' (which might be set by the user in the environment), and
`CPPFLAGS' before `CFLAGS'.
* builds/freetype.mk (FT_CFLAGS): Don't add `INCLUDE_FLAGS'.
(FT_COMPILE): Make this a special variable for compiling only the
files handled in `freetype.mk'.
(.c.$O): Removed, unused.
* src/*/rules.mk (*_COMPILE): Fix order of include directories.
We use a cast to indicate that we intentionally ignore a function's
return value. However, this doesn't apply to API functions where
errors can only happen for trivially invalid input.
* src/base/ftstroke.c (FT_Glyph_Stroke, FT_Glyph_StrokeBorder),
src/base/ftsynth.c (FT_GlyphSlot_Embolden), src/cff/cffgload.c
(cff_slot_load), src/pfr/pfrdrivr.c (pfr_get_kerning),
src/type1/t1load.c (parse_encoding), src/type42/t42parse.c
(t42_parse_encoding): Do it.
This is a follow-up to Savannah bug #43659.
* src/type42/t42objs.c (T42_Face_Init): Exclusively use the
`truetype' font driver for loading the font contained in the `sfnts'
array.
* src/type42/t42objs.c (T42_Open_Face): Initialize `face->ttf_size'.
* src/type42/t42parse.c (t42_parse_sfnts): Always set
`face->ttf_size' directly. This ensures a correct stream size in
the call to `FT_Open_Face', which follows after parsing, even for
buggy input data.
Fix error messages.
