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.
* src/cff/cffparse.c (cff_parser_init): Add new parameter to pass
the number of Multiple Master axes.
Update all callers.
(cff_parse_multiple_master): Get number of axes.
(cff_parser_run) <opcode 31>: Updated.
* src/cff/cffparse.h: Updated.
(CFF_ParserRec): Add `num_axes' field.
* src/cff/cffload.c: Updated.
* src/cff/cfftypes.h (CFF_FontRecDictRec): Add `num_axes' field.
We need this to properly trace Multiple Master CFFs, which contain
two SIDs that are charstrings.
This commit makes FreeType also show the last SID, omitted
previously due to a bug.
* src/cff/cfftypes.h (CFF_FontRec): Add `string_pool_size' field.
* src/cff/cffload.c (cff_index_get_pointers): Add argument to return
the pool size.
Update all callers.
* src/cff/cffobjs.c (cff_face_init) [FT_DEBUG_LEVEL_TRACE]: Directly
access `cff->strings' to display the non-default strings.
The new code only displays the first master in the font.
* src/cff/cffgload.c (cff_decode_parse_charstrings): Add new
parameter to allow function calls from dictionaries also.
<cff_op_blend>: Partially implement it.
Update all callers.
* src/cff/cffgload.h: Updated.
* src/cff/cffparse.c (cff_parser_init): Add new parameter to pass the
number of Multiple Master designs.
Update all callers.
(cff_parse_multiple_master): New function to rudimentarily parse
operator.
(cff_parser_run): Handle `T2' operator.
* src/cff/cffparse.h: Updated.
(CFF_ParserRec): Add `num_designs' field.
* src/cff/cffload.c: Updated.
* src/cff/cfftoken.h: Handle `MultipleMaster' operator.
* src/cff/cfftypes.h (CFF_FontRecDictRec): Add `num_designs' field.
* src/sfnt/sfobjs.c (sfnt_init_face): Don't handle `fvar' table for
MM CFFs.
* src/cff/cf2intrp.c (cf2_interpT2CharString) [cf2_cmdEXTENDEDNMBR,
default]: `|' is not guaranteed to be processed from left to right
by the compiler. However, the code repeatedly calls
`cf2_buf_readByte' to get the arguments to `|' ... Fix this.
Both the native CFF hinter and the auto-hinter now have a very
similar rendering style.
* include/freetype/freetype.h: Mention that FT_LOAD_TARGET_LIGHT no
longer implies FT_LOAD_FORCE_AUTOHINT.
* include/freetype/ftmodapi.h (FT_MODULE_DRIVER_HINTS_LIGHTLY): New
macro.
* include/freetype/internal/ftobjs.h (FT_DRIVER_HINTS_LIGHTLY): New
macro.
* src/cff/cffdrivr.c (cff_driver_class): Use it.
* src/base/ftobjs.c (FT_Load_Glyph): Update auto-hinter selection
logic.
This modifies the addition of subroutine number to subroutine bias
from unsigned to signed, but does not change any results.
* src/cff/cf2ft.c (cf2_initGlobalRegionBuffer,
cf2_initLocalRegionBuffer): Change variable names from (unsigned)
`idx' to (signed) `subrNum', since it is not an index until after
the bias is added.
* src/cff/cf2ft.h: Updated.
* src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdCALLSUBR>:
Updated similarly.
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/t1gload.c (T1_Load_Glyph): Directly modify advances only
if font matrix is not trivial.
* src/cff/cffgload.c (cff_slot_load): Ditto.
* sff/cid/cidgload.c (cid_slot_load_glyph): Ditto for advances and the
entire outline.

for a rationale.
* src/autofit/afpic.h, src/base/basepic.h, src/cff/cffpic.h,
src/pshinter/pshpic.h, src/psnames/pspic.h, src/raster/rastpic.h,
src/sfnt/sfntpic.h, src/smooth/ftspic.h, src/truetype/ttpic.h
(FT_BEGIN_HEADER, FT_END_HEADER): Move macro calls to not enclose
header files that contain FT_{BEGIN,END}_HEADER macros by
themselves.
* src/autofit/aftypes.h [FT_DEBUG_AUTOFIT]: Include
FT_CONFIG_STANDARD_LIBRARY_H earlier.
* src/truetype/ttpic.h: Include FT_INTERNL_PIC_H.
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.
* src/cff/cf2intrp.c (cf2_interpT2CharString): The opcodes
`vvcurveto', `hhcurveto', `vhcurveto', and `hvcurveto' all iterate,
pulling values off the stack until the stack is exhausted.
Implicitly the stack must be a multiple (or for subtly different
behaviour) a multiple plus a specific number of extra values deep.
If that's not the case, enforce it (as the old code did).
* src/cff/cf2ft.c (cf2_getSeacComponent): When using the incremental
interface to retrieve glyph data for a SEAC, it be left to the
incremental interface callback to apply the encoding to raw
character index (as it was in the previous code).
Problem reported by Behdad.
* src/cff/cffdrivr.c (cff_get_advances): Handle SFNT case
separately.
* src/cff/cffgload.c (cff_slot_load): Use advance width and side
bearing values from `hmtx' table if present.
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.
