Behdad Esfahbod 8eed9cb11e [kern] Fix invalid memory access if offset is zero 
If offset is zero, we return Null() object.  Wasn't prepared for that.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=4088

Khaled Hosny b68fba4dc8 [test] Use glyph ids instead of forcing ft funcs 
We were using ft funcs because these are CFF fonts, but we can avoid
glyph names instead and keep testing both ot and ft.

Behdad Esfahbod c4f4c0a2fa Fix indexing in unsafe-to-break marking for 'stch' feature 
Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=4099

Behdad Esfahbod 822035ce73 [tests/arabic-stch.tests] Don't show flags 
We don't need to test the actual flag values.  For unsafe-to-break,
the --verify in run-tests.sh checks what we are interested in.

Behdad Esfahbod 4b3278ef8d [ot] Hook up horizontal kerning to kern table 
Seems to work.  Yay!

Still to do: run kerning if GPOS doesn't have 'kern' feature.

Khaled Hosny 0e63cbed9c [test] Fix difference between ft and ot font funcs 
See https://github.com/behdad/harfbuzz/pull/590#issuecomment-341194673.

I simply removed the composite glyph and use the referenced simple
glyph directly.

Khaled Hosny 70137e2b4b [test] We don’t care about glyph positions here 
Freetype and OT font functions give different positions for some glyphs
in this font (OT seems to be correct), but that is not what we are
interested in in this test.

See https://github.com/behdad/harfbuzz/pull/590#issuecomment-341045223.

Khaled Hosny afbfb9279c [test] Always use ft font funcs for these tests 
These are CFF fonts and ot functions don’t support CFF glyph names yet.
The next commit will run all tests with ot functions.
