Birunthan Mohanathas 6bf9db4f1e [ft] Fix unsafe cast of FT_Done_Face in hb_ft_{face,font}_create_referenced (#289)
Prior to this change the function `FT_Error FT_Done_Face(FT_Face *)` was
called through a pointer with the signature `void (void *)` resulting in
undefined behaviour.

Behdad Esfahbod 30e6e29f0f [indic/use] Move Javanese from Indic shaper to USE
Fixes https://github.com/behdad/harfbuzz/issues/243

With javatext.ttf, the reodering medial Ra gets its advance width
zero'ed in Uniscribe implementation, and the font adds the advance
back.  Our Indic shaper does not do that, but USE does.  So, route
Javanese through USE.  That's what Microsoft does anyway.  Test:

  U+A9A5,U+A9BA

This also seems to fix the following sequence, and variations thereof:

  U+A99F,U+A9C0,U+A9A2,U+A9BF

Behdad Esfahbod 69f9fbc420 Synthesize GDEF glyph class for any glyph that does not have one in GDEF
Previously we only synthesized GDEF glyph classes if the glyphClassDef
array in GDEF was null.  This worked well enough, and is indeed what
OpenType requires: "If the font does not include a GlyphClassDef table,
the client must define and maintain this information when using the
GSUB and GPOS tables."  That sentence does not quite make sense since
one needs Unicode properties as well, but is close enough.

However, looks like Arial Unicode as shipped on WinXP, does have GDEF
glyph class array, but defines no classes for Hebrew.  This results
in Hebrew marks not getting their widths zeroed.  So, with this change,
we synthesize glyph class for any glyph that is not specified in the
GDEF glyph class table.  Since, from our point of view, a glyph not
being listed in that table is a font bug, any unwanted consequence of
this change is a font bug :).

Note that we still don't get the same rendering as Uniscribe, since
Uniscribe seems to do fallback positioning as well, even though the
font does have a GPOS table (which does NOT cover Hebrew!).  We are
not going to try to match that though.

Test string for Arial Unicode:

	U+05E9,U+05B8,U+05C1,U+05DC

Before:		[gid1166=3+991|gid1142=0+737|gid5798=0+1434]
After:		[gid1166=3+991|gid1142=0+0|gid5798=0+1434]
Uniscribe:	[gid1166=3+991|gid1142=0@348,0+0|gid5798=0+1434]

Note that our new output matches what we were generating until July
2014, because the Hebrew shaper used to zero mark advances based on
Unicode, NOT GDEF.  That's 9e834e29e0.

Behdad Esfahbod 731a430cd3 Fix requiredFeature stage handling logic
Originally the way Jonathan had written this was correct in
"continue"ing:

35e28c7a73 (diff-ead86a33a5cc9ad7f6e6381031a0baddR199)

When I rewrote his patch, I messed it up:

da13293798 (diff-ead86a33a5cc9ad7f6e6381031a0baddR209)

the intended behavior was NOT to set found=TRUE and NOT to continue.
This was resulting in feature_index[table_index] being left unset.

Behdad Esfahbod 91dd115652 Add HB_NDEBUG
API changes:
- If NDEBUG is defined, define HB_NDEBUG
- Disable costlier sanity checks if HB_NDEBUG is defined.

In 1.2.3 introduced some code to disable costly sanity checks if
NDEBUG is defined.  NDEBUG, however, disables all assert()s as
well.  With HB_NDEBUG, one can disable costlier checks but keep
assert()s.

I'll probably add a way to define HB_NDEBUG automatically in
release tarballs.  But for now, production systems that do NOT
define NDEBUG, are encouraged to define HB_NDEBUG for our build.

Behdad Esfahbod ebd7431f82 Partially revert 86c68c7a2c
That commit moved the advance adjustment for mark positioning to
be applied immediately, instead of doing late before.  This breaks
if mark advances are zeroed late, like in Arabic.  Also, easier to
hit it in RTL scripts since a single mark with non-zero advance is
enough to hit the bug, whereas in LTR, at least two marks are needed.
