8ba8042821 [Indic] Fix consonant position font lookup logic 
Oops.  I broken this badly and the test suite did not notice.  That
worries me.  Have to investigate.

71baea0062 [OT] Use general-category, not GDEF class, to decide to zero mark advances 
At this point, the GDEF glyph synthesis looks pointless.  Not that I
have many fonts without GDEF lying around.

As for mark advance zeroing when GPOS not available, that also is being
replaced by proper fallback mark positioning soon.

afbcc24be0 [GSUB] Wire the font, not just the face, down to substitute() 
We need the font for glyph lookup during GSUB pauses in Indic shaper.
Could perhaps be avoided, but at this point, we don't mean to support
separate substitute()/position() entry points (anymore), so there is
no point in not providing the font to GSUB.

1336ecdf8e [GSUB/GPOS] Use Coverage digests as gatekeeper 
Gives me a good 10% speedup for the Devanagari test case.  Less so
for less lookup-intensive tests.

For the Devanagari test case, the false positive rate of the GSUB digest
is 4%.

1e7d860613 [GPOS] Adjust mark advance-width zeroing logic 
If there is no GPOS, zero mark advances.

If there *is* GPOS and the shaper requests so, zero mark advances for
attached marks.

Fixes regression with Tibetan, where the font has GPOS, and marks a
glyph as mark where it shouldn't get zero advance.
