Remove ClassDef->Defined field. This is the comment accompanying it:
2009-01-29 Behdad Esfahbod <behdad@gnome.org>
* pango/opentype/harfbuzz-open.h:
* pango/opentype/harfbuzz-gdef.c (Make_ClassRange),
(HB_GDEF_Build_ClassDefinition):
* pango/opentype/harfbuzz-gpos.c (Load_PosClassRule),
(Load_ChainPosClassRule):
* pango/opentype/harfbuzz-gsub.c (Load_SubClassRule),
(Load_ChainSubClassRule):
* pango/opentype/harfbuzz-open.c (Load_ClassDef1),
(Load_ClassDef2), (_HB_OPEN_Load_ClassDefinition),
(_HB_OPEN_Load_EmptyClassDefinition),
(_HB_OPEN_Free_ClassDefinition):
Remove ClassDef->Defined field. This is the comment accompanying it:
The `Defined' field is not defined in the OpenType specification
but apparently needed for processing fonts like trado.ttf: This
font refers to a class which contains not a single element. We
map such classes to class 0.
The comment is correct that trado.ttf (MS Traditional Arabic) uses
such classes. However, in my testing I couldn't identify any
problems with the font if the special handling is removed. I also
processed as many fonts as I could get my hand on and trado.ttf was
the only not-totally-broken font hitting the special-case code.
DejaVu fonts hit it too, but I'm sure they do not require the
special-handling code. Most probably, that code introduces bugs
in them.
The special-casing was consuming lots of memory. EIGHT MEGABYTES
for loading DejaVu Sans! While this could be complete fixed, I
decided to remove the special-handling code altogether. I don't
think it will make any real difference, and if it does, we'll fix
fonts. Such hacks will not be in harfbuzz-ng anyway.
Bug originally reported by nsf.

Bug 485559 – Boston Summit HarfBuzz optimizations
2007-10-10 Behdad Esfahbod <behdad@gnome.org>
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.
