Behdad Esfahbod 7368da6724 [test] Add test for cursive-positioning with mixed directions
Fails now.  Fix coming.  See thread "Issue with cursive attachment"
started by Khaled.  Test fonts were made by modifying test font
from Khaled to add more anchors.

Romain Naour 160f635523 fix static linking with icu-uc
When linking test-unicode statically it needs $(ICU_LIBS)
which contains all required flags.
Especially -lstdc++.

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.

Behdad Esfahbod 9868749abe [test] Use /usr/bin/env python instead of /usr/bin/python
Bug 76494 - #!/usr/bin/python in testsuite

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.

Micro tests added using Noto Sans Oriya draft.

Behdad Esfahbod b5fbc3b8f5 API: Do not clear buffer-flags in hb_buffer_clear_contents()
After 763e5466c0, one doesn't
need to set flags for different pieces of text.  The flags now
are something the client sets up once, depending on how it
actually uses the buffer.  As such, don't clear it in
clear_contents().

Tests updated.

Behdad Esfahbod 164c13d73f Another try to fix Mongolian free variation selectors
This reverts bf029281 and fixes it properly.  That commit

Behdad Esfahbod 976c8f4552 New API: hb_buffer_[sg]et_replacement_codepoint()
With this change, we now by default replace broken UTF-8/16/32 bits
with U+FFFD.  This can be changed by calling new API on the buffer.
Previously the replacement value used to be (hb_codepoint_t)-1.

Note that hb_buffer_clear_contents() does NOT reset the replacement
character.

See discussion here:

6f13b6d62d

New API:

  hb_buffer_set_replacement_codepoint()
  hb_buffer_get_replacement_codepoint()

Behdad Esfahbod 3b861421a7 Fix Mongolian Variation Selectors for fonts without GDEF
Originally we fixed those in 79d1007a50.
However, fonts like MongolianWhite don't have GDEF, but have IgnoreMarks
in their LigatureSubstitute init/etc features.  We were synthesizing a
GDEF class of mark for Mongolian Variation Selectors and as such the
ligature lookups where not matching.  Uniscribe doesn't do that.

I tried with more sophisticated fixes, like, if there is no GDEF and
a lookup-flag mismatch happens, instead of rejecting a match, try
skipping that glyph.  That surely produces some interesting behavior,
but since we don't want to support fonts missing GDEF more than we have
to, I went for this simpler fix which is to always mark
default-ignorables as base when synthesizing GDEF.

Micro-test added.

Behdad Esfahbod 2b051c6057 Rename HB_VERSION_CHECK and hb_version_check to "atleast"
HB_VERSION_CHECK's comparison was originally written wrongly
by mistake.  When API tests were written, they were also written
wrongly to pass given the wrong implementation... Sigh.

Given the purpose of this API, there's no point in fixing it
without renaming it.  As such, rename.

API changes:

  HB_VERSION_CHECK -> HB_VERSION_ATLEAST
  hb_version_check -> hb_version_atleast

Behdad Esfahbod 1d634cbb4b Fix base-position when 'pref' is NOT formed
If pre-base reordering Ra is NOT formed (or formed and then
broken up), we should consider that Ra as base.  This is
observable when there's a left matra or dotreph that positions
before base.

Now, it might be that we shouldn't do this if the Ra happend
to form a below form.  We can't quite deduce that right now...
