Bug 488840 – harfbuzz: protect against ligid overflow
* pango/opentype/harfbuzz-buffer.c (_hb_buffer_allocate_ligid):
Never return zero, even in case of overflow.
* pango/opentype/harfbuzz-impl.h: Define dummy HB_LIKELY() and
HB_UNLIKELY(), to be filled later.
2007-10-11 Behdad Esfahbod <behdad@gnome.org>
* pango/opentype/*: Mark internal symbols as HB_INTERNAL and
define that to static in harfbuzz.c.
* pango/opentype/harfbuzz-buffer-internal.h: New file.
2007-10-11 Behdad Esfahbod <behdad@gnome.org>
* pango/opentype/Makefile.am: Build harfbuzz.c instead of individual
source files, to let compiler go wild with optimizations!
2007-10-11 Behdad Esfahbod <behdad@gnome.org>
* pango/opentype/Makefile.am: Don't include harfbuzz-dump.[ch] in
libharfbuzz.a. Those are just used by the harfbuzz-dump tool.
2007-10-11 Behdad Esfahbod <behdad@gnome.org>
* pango/opentype/harfbuzz-buffer.[ch]: Rename buffer->inplace to
buffer->separate_out with the inverted meaning, such that buffer
is initialization is memset(0).

Bug 485621 – Get rid of freetype memory allocator in harfbuzz

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.

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

those systems that don't track dependencies automatically.

Some automake versions seem to use it or something.

and have many cpu usage.
Patch from Yong Li.
* pango/opentype/ftglue.c (_hb_ftglue_face_goto_table): TrueType table

* 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
