Behdad Esfahbod 6804b61d2e [subset] Add hb_subset_face 
It's a hb_face_t that has add_table() and in the future knows how to
compile itself into a font blob.

Behdad Esfahbod 2da0d87e76 Remove NullPool visibility hack 
We keep a separate private NullPool in libharfbuzz-subset.so
This can fire back later since now there are two separate null objects,
and comparisons to the null pool can be confused.  Something to deal
with when it comes up. Ouch!

Behdad Esfahbod cc1e0840ba [buffer] Tweak diff re glyph_flags again

Meh. Makes MORX tests pass now. Need to better define the behavior.

Behdad Esfahbod 3615f344ec [test/text-rendering-tests] Update from upstream 2018-02-04 17:21:27 -05:00
Behdad Esfahbod 54e6efadd6 [aat] Fix unsafe-to-break 
At any position, if state is not zero, mark unsafe-to-break before,
unless we can reason it safe.

At any position, if there's an action entry for end-of-text, mark
unsafe to break.

Also changes buffer diff impl to allow for flag differences as long
as the buffer glyph flags are superset of reference glyph flags.

With this, all MORX tests pass.
