ab1f30bd05 [kerx] Implement Format6 
Untested.  The only Apple font shipping with this format is San Francisco fonts
that use this for their kerx variation tables, which we don't support.

7ed5366d3c [kerx] No-op 
Tested that Format0 works with Kannada MN font:

$ make -j5 lib -s && HB_OPTIONS=aat ./hb-shape Kannada\ MN.ttc -u 0C95,0CC2
[kn_ka=0+1000|kn_matra_uu=0@-30,0+1345]

$ make -j5 lib -s && HB_OPTIONS=aat ./hb-shape Kannada\ MN.ttc -u 0C95,0CC2 --features=-kern
[kn_ka=0+1030|kn_matra_uu=0+1375]

Note that GPOS does the same with 'dist' feature, and applies the whole difference to the
same glyph:

$ make -j5 lib -s && ./hb-shape Kannada\ MN.ttc -u 0C95,0CC2
[kn_ka=0+970|kn_matra_uu=0+1375]

$ make -j5 lib -s && ./hb-shape Kannada\ MN.ttc -u 0C95,0CC2 --features=-dist
[kn_ka=0+1030|kn_matra_uu=0+1375]

5d34164d98 [kern/kerx] Fix offset base 
Disable kern Format2.

Fix kerx Format2.  Manually tested this with Tamil MN font and it works:

$ HB_OPTIONS=aat ./hb-shape Tamil\ MN.ttc -u 0B94,0B95
[tgv_au=0+3435|tgc_ka=1@-75,0+1517]

 HB_OPTIONS=aat ./hb-shape Tamil\ MN.ttc -u 0B94,0B95 --features=-kern
[tgv_au=0+3510|tgc_ka=1+1592]

1e8fdd285f Remove HAVE_OT 
We never tested compiling without it.  Just kill it.  We always build
our own shaper.

b3390990f5 Add per-subtable set-digests 
This speeds up Roboto shaping by ~10%.  I was hoping for more.
Still, good defense against lookups with many subtables.

e655fd38cf Apply TT or fallback kerning when GPOS does not have kern feature 
Previously we only did if there was no GPOS whatsoever.  This applies
to Arial, Times New Roman, etc in Win7.  Was not kerning before.  It
is now.

be2f148da4 [ft] Use mutex to lock access to FT_Face 
Makes our FT-backed hb_font_t safe to use from multiple threads.  Still,
the underlying FT_Face should NOT be used from other threads by client
or other libraries.

Maybe I add a lock()/unlock() public API ala PangoFT2 and cairo-ft.
Maybe not.
