Werner Lemberg e9a746674a Fix handling of self-delimiting tokens. 2006-06-26 17:37:44 +00:00
Werner Lemberg c011f4cba1 The Type 1 parser now skips over top-level procedures as required
for a `Simplified Parser'.  This makes the parser more robust as it
doesn't poke around in PostScript code.  Additionally, it makes the
FontDirectory hackery in src/type1/t1load.c unnecessary.

* src/psaux/psobjs.c (IS_OCTAL_DIGIT): New macro.
(skip_literal_string): Add FT_Error as return value.
Handle escapes better.
(skip_string): Add FT_Error as return value.
Don't set `parser->error' but return error code directly.
(skip_procedure): New function.
(ps_parser_skip_PS_token): Handle procedures.
Update code.
(ps_parser_to_token): Update code.
(ps_parser_load_field_table): Handle bbox entries also.

* src/type1/t1load.c (parse_dict): Remove FontDirectory hackery.
Add commented-out code for synthetic fonts.

src/psaux/t1cmap.c, src/psnames/psmodule.c: Fix for the memory
        leak described in bug #16759.

        We change 'ps_unicodes_init' so that it also takes a 'free_glyph_name'
        callback to release the glyph names returned by 'get_glyph_name'

David Turner 0971735dce * src/pfr/pfrobjs.c (pfr_face_init): fix the computation

  guarantee that glyph index 0 corresponds to the "missing
  glyph"

David Turner 281679de85 * include/freetype/internal/tttypes.h, src/autofit/afangles.c,
src/autofit/afcjk.c, src/autofit/afhints.c, src/autofit/aflatin.c,
        src/autofit/aftypes.h, src/base/ftcalc.c, src/base/ftoutln.c,
        src/gzip/ftgzip.c, src/psaux/psconv.c, src/truetype/ttgload.c,
        src/type1/t1gload.c:

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.

David Turner dc3ff31c3f * src/ftccmap.c (FTC_CMapCache_Lookup): changed the threshold

        some segmentation faults with fonts like KozMinProVI-Regular.otf
        which comes from the Japanese Adobe Reader Asian Font pack.
