Behdad Esfahbod 6e6f82b6f3 Implement SYRIAC ABBREVIATION MARK with 'stch' feature
The feature is enabled for any character in the Arabic shaper.
We should experiment with using it for Arabic subtending marks.
Though, that has a directionality problem as well, since those
are used with digits...

Behdad Esfahbod da29b43794 Separate nil font-funcs from parent-peeking font-funcs
API change: all fonts created with hb_font_create() now inherit from
(ie have parent) hb_font_get_empty().

Behdad Esfahbod 04fd8517f8 Add tests for hyphen fallback
U+2011 is <noBreak> equivaent of U+2010, so we should do the fallback
for it.  Currently fails.

Behdad Esfahbod 49ef630936 Adjust the width of various spaces if font does not cover them
See discussion here:
81ef4f407d

There's no way to disable this fallback, but I don't think it would
be needed.  Let's hope for the best!

Behdad Esfahbod 7793aad946 Normalize various spaces to space if font doesn't support
This resurrects the space fallback feature, after I disabled
the compatibility decomposition.  Now I can release HarfBuzz
again without breaking Pango!

It also remembers which space character it was, such that later
on we can approximate the width of this particular space
character.  That part is not implemented yet.

We normalize all GC=Zs chars except for U+1680 OGHA SPACE MARK,
which is better left alone.

Behdad Esfahbod df698f3299 [ot-font] Fix hmtx table length checking, *again*

and introduced the exact same issue again. :(
Good thing we have ongoing fuzzing going now.  Was discovered
immediately by libFuzzer.  Thanks kcc!

parent into a font...

Behdad Esfahbod 1866e17114 Make hb_font_create_sub_font() NOT make parent immutable
We don't rely on that.  However, whenever hb_font_make_immutable()
is called, it makes its parenting chain immutable.

Sascha Brawer f2ad935e19 Handle language tags that indicate phonetic IPA transcription
The BCP-47 registry defines a variant subtag "fonipa" that can be used
in combination with arbitrary other language tags. For example,
"rm-CH-fonipa-sursilv" indicates the Sursilvan dialect of Romansh
as used in Switzerland, transcribed used the International Phonetic
Alphabet.

Behdad Esfahbod b3a2f6afba [test] Add test for cluster merging
Based on test from https://code.google.com/p/chromium/issues/detail?id=497578

Currently fails.  Basically, if there's a default_ignorable at the
start of text, and font has no space glyph, we remove the default_ignorable,
and that makes the first char in text to correspond to no cluster.

Fix coming.

Behdad Esfahbod eb0bf3ae66 Relax inert checks
Previously, when creating an object from inert inputs (eg:
"hb_font_create(hb_face_get_empty())") we returned the inert
empty object.  This is not helpful as there are legitimate
usecases to do that.

We now never return the inert object unless allocation failed.

Tests are revised to reflect.

Ebrahim Byagowi 363ceec3fb Make hb_test_tools.py compatible with python 3
On ArchLinux, /usr/bin/python is linked to python 3 so
HarfBuzz `make check` is broken there.

This makes hb_test_tools.py compatible with python 3 while
no breaking it on python 2.

Behdad Esfahbod 7d5e7613ce Fail blob creation if length overflows or is too large
Fail if blob start plus length overflows; or if blob length
is greater than 2GB.  It takes a while for fonts to get to that
size.  In the mean time, it protects against bugs like this:

  http://www.icu-project.org/trac/ticket/11450

Also avoids some weird issues with 32bit vs 64bit systems
as we accept length as unsigned int.  As such, a length of
-1 will cause overflow on 32bit machines, but happily
accepted on a 64bit machine.  Avoid that.

Behdad Esfahbod e6f80fa104 [indic] Allow ZWJ/ZWNJ before SM
In Oriya, a ZWJ/ZWNJ might be added before candrabindu to encourage
or stop ligation of the candrabindu.  This is clearly specified in
the Unicode section on Oriya.  Allow it there.  Note that Uniscribe
doesn't allow this.
