Garret Rieger 4ff09274a8 [subset] In CFF accelerator keep a reference to original face.
The charstring objects reference memory from the original face so we need to maintain a reference to prevent it from being destroyed.

Garret Rieger 48b6837074 [subset] add a CFF specific accelerator object.
This allows CFF specific accelerator structures to be isolated to the CFF code.

Behdad Esfahbod 2e9b270a49 [hb-view] Fix cairo slanting condition
hb-draw already does slanting. If NOT hb-draw, we should slant
through cairo path.  Donno why this was untested before.

This was double-slanting with hb-draw, and not slanting without it.

Behdad Esfahbod 404cb99d86 [buffer-diff] Fix check for glyph flag equality
I'm not sure if the old behavior was intentional, but it was checking
that the glyph flags were a subset of the reference buffer's glyph
flags.  I don't see why that is useful.  Fix that.

Then make the buffer-verify code ignore flag differences when verifying
buffers, since our unsafe-to-concat flag at least, is conservative and
not guaranteed to be produced the same in fragments.  See:
