The font variation code. All parts dependent on the GX code in the
`truetype' module are guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT.
In other words, you can still compile the `cff' module without
defining TT_CONFIG_OPTION_GX_VAR_SUPPORT (which brings you CFF2
support without font variation).
* src/cff/cf2font.c (cf2_font_setup): Add support for font
variation.
* src/cff/cf2font.h (CF2_Font): Add fields for variation data.

* src/truetype/ttgxvar.c (TT_Get_MM_Var): `CFF2' is equal to `gvar',
since glyph variation data is directly embedded.
(TT_Set_MM_Blend): Don't load `gvar' table for CFF2 fonts.
Now all glyphs of MM CFFs like `ITCGaramondMM-It.otf' can be
displayed.
* src/cff/cffgload.c (cff_decoder_parse_charstrings) <cff_op_store,
cff_op_load>: Partially implement it.

parameter to allow function calls from dictionaries also.

MM CFFs.
* src/cff/cffload.c, src/cff/cffload.h, src/cff/cffobjs.c,
src/cff/cffparse.c, src/cff/cffparse.h: Add library pointer to
'CFF_ParserRec' set by `cff_parser_init'.
Route library pointer from 'cff_face_init' to 'cff_subfont_load'
for `cff_parser_init'.
* src/cff/cffparse.c (CFF_Field_Handler): Move it to...
* src/cff/cffparse.h: This file, to be used by other C files.
FT_INTERNAL_OBJECTS_H.
* src/base/ftstroke.c (FT_Outline_GetInsideBorder,
FT_Outline_GetOutsideBorder): s/or/o/ to make it compile with
C++ compilers.
* src/cache/ftcmru.c, include/freetype/cache/ftcmru.h:
s/select/selection/ to avoid compiler warning.
* src/cff/cffload.h: s/select/ftselect/ to avoid potential
compiler warning.
Formatting.
* include/freetype/internal/cfftypes.h, src/cff/cfftypes.h,
src/cff/cffload.h, src/cff/cffobjs.h, src/cff/cffparse.h,
include/freetype/internal/services/svbdf.h: moving "cfftypes.h" from
'include/freetype/internal' to 'src/cff' since no other modules needs
to known about these types
* include/freetype/internal/t42types.h,
include/freetype/internal/internal.h, src/type42/t42objs.h,
src/type42/t42drivr.c, src/type42/t42types.h: moving "t42types.h" from
'include/freetype/internal' to 'src/type42' since no other modules needs
to known about these types

include/freetype/internal/ftserv.h, src/cff/cffdrivr.c,
src/cid/ciddrivr.c, src/type1/t1driver.c, src/type42/t42drivr.c,
src/base/fttype1.c: migrating to FT_SERVICE_ID_POSTSCRIPT_INFO defined
in "svpsinfo.h", removing some sad hacks.
to support charmaps for CFF fonts
* src/cff/cffload.c, src/cff/cffload.h, src/cff/cffobjs.c,
src/cff/cffobjs.h, src/cff/cffparse.c, src/cffparse.h, src/cff/cffgload.c,
src/cff/cffgload.h: adding support for CFF charmaps, reformatting the
sources, and removing some bugs in the Encoding and Charset loaders
