Bug 485621 – Get rid of freetype memory allocator in harfbuzz
* pango/opentype/*: Remove all occurences of FT_Memory. Use
malloc/realloc/free directly.
* pango/pango-ot*: Update to above.

Bug 485559 – Boston Summit HarfBuzz optimizations
* pango/opentype/*: HarfBuzz hacking to:
- Rename last remaining FT_Err stuff to HB_Err.
- Fix a couple invalid table paths to be permissive so
fonts work better. Particularly GDEF table for Nafees
Nastaliq is loaded and works great now.
- Optimize harfbuzz buffer to not copy/swap for simple
one-to-one and "copy" GSUB operations.
* pango/pango-ot*: Update to FT_Err to HB_Err renaming.

Bug 302952 – The placement of a diacritic marks for an arabic ligature
is not correct
* pango/opentype/harfbuzz-buffer.c (hb_buffer_allocate_ligid): Don't
use zero as allocated ligature id. Zero means no ligature id.

(Lookup_PairPos2), (Lookup_PairPos), (Do_ContextPos):

2007-08-20 Behdad Esfahbod <behdad@gnome.org>
* pango/opentype/harfbuzz-gsub.c (GSUB_Do_String_Lookup): Don't

sent to harfbuzz-list.
2007-04-30 Behdad Esfahbod <behdad@gnome.org>

and have many cpu usage.

Fix minor bugs reported by the Coverity scan report.
* pango/opentype/harfbuzz-gdef.c (HB_GDEF_Build_ClassDefinition):
* pango/opentype/harfbuzz-gpos.c (HB_GPOS_Query_Scripts),
(HB_GPOS_Query_Languages), (HB_GPOS_Query_Features): Do not access
structs before we check them for nullity.
* pango/pango-layout.c (pango_layout_index_to_line),
(pango_layout_index_to_line_and_extents),
(pango_layout_index_to_pos): Check for invalid iterators outside the
loop, so we don't crash.
* pango/pango-layout.c (pango_layout_line_x_to_index): Set
char_trailing instead of trailing in one of too many paths. Should
have been a typo.
* pango/pangox.c (get_font_metrics_from_subfonts): Check for nullity
somewhere.
2006-04-03 Behdad Esfahbod <behdad@gnome.org>
* pango/opentype/harfbuzz-impl.h: Make sure TTAG_GDEF and frineds are
defined, needed for FreeType <= 2.1.7 (pointed by Tim Janik).
