+ [cache] Change the hash types to FT_PtrDist.
+ On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)

- (Ins_MD): Last regression fix.
+ [ftraster] Pacify compiler.
- * src/autofit/aflatin.c (af_latin_metrics_init_blues): Fix blues
- computations in order to ignore single-point contours. These are
- never rasterized and correspond in certain fonts to mark-attach
- points that are very far from the glyph's real outline, ruining the
- computation.
+ * src/raster/ftraster.c (ft_black_new) [_STANDALONE_]: `memory' is

- * src/autofit/afloader.c (af_loader_load_g): In the case of

- Otherwise code that uses them will most certainly ruin the fixed
- advance property.

+ Previously we discovered fonts which used `setcurrentpoint' to set

- Handle unknown othersubrs gracefully: count their operands and let
- the following pop operators push the operands as the results onto

-
- 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.

- theoretically happen. This fixes Savannah bug #16669.

- * src/pfr/pfrobjs.c (pfr_face_init): Fix the computation
- of `face->num_glyphs' which missed the last glyph, due to

-
- This is a major patch used to drastically improve the performance of
- loading glyphs. This both speeds up loading the glyph vectors
- themselves and the auto-fitter module.
-
- We now use inline assembler code with GCC to implement `FT_MulFix',
- which is probably the most important function related to the
- engine's performance.
-
- The resulting speed-up is about 25%.
-
-
- * include/freetype/internal/tttypes.h (TT_LoaderRec): Add fields
- `cursor' and `limit'.
-
- * src/autofit/afangles.c (af_corner_is_flat, af_corner_orientation):
- New functions.
- (AF_ATAN_BITS, af_arctan, af_angle_atan): Comment out.
- [TEST]: Remove.
-
- * src/autofit/afcjk.c (AF_Script_UniRangeRec): Comment out test
- code.
-
- * src/autofit/afhints.c (af_axis_hints_new_segment): Don't call
- `FT_ZERO'
- (af_direction_compute, af_glyph_hints_compute_inflections): Rewritten.
- (af_glyph_hints_reload: Rewrite recognition of weak points.
-
- * src/autofit/aflatin.c (af_latin_hints_compute_segments): Move
- constant values out of the loops.
-
- * src/autofit/aftypes.h: Updated.
-
- * src/base/ftcalc.c (FT_MulFix): Use inline assembler code.
-
- * src/base/ftoutln.c (FT_Outline_Get_Orientation): Use vector
- product to get orientation.
-
- * src/gzip/ftgzip.c (ft_get_uncompressed_size): New function.
- (FT_Stream_OpenGzip): Use it to handle small files directly in
- memory.
-
- * src/psaux/psconv.c (PS_Conv_ASCIIHexDecode, PS_ConvEexecDecode):
- Improve performance.
-
- * src/truetype/ttgload.c (TT_Access_Glyph_Frame): Set `cursor' and
- `limit'.
-
- (TT_Load_Glyph_Header, TT_Load_Simple_Glyph,
- TT_Load_Composite_Glyph): Updated. Add threshold to protect against
- exceedingly large values of number of contours. Speed up by
- reducing the number of loops.
-
- * src/type1/t1gload.c (T1_Load_Glyph): Don't apply unit matrix.
-
-
- * src/cache/ftccmap.c (FTC_CMapCache_Lookup): Change the threshold
- used to detect rogue clients from 4 to 16. This is to prevent some
- segmentation faults with fonts like `KozMinProVI-Regular.otf' which
- comes from the Japanese Adobe Reader Asian Font pack.
-
-2007-05-17 Werner Lemberg <wl@gnu.org>

+ * src/truetype/ttgload.c (tt_get_metrics_incr_overrides)
+ [FT_CONFIG_OPTION_INCREMENTAL]: New function, split off from...
+ (tt_get_metrics): This.
+ Updated.
+ (load_truetype_glyph): Use tt_get_metrics_incr_overrides.
