6a37a65276 [trak] Choose closest trak track to 0.0 
Seems to be what CT does. Needs more testing to adjust better, but
for now it's better than before.

c737829449 [OT] Remove likely() from coverage check 
Not that it matters, but because of the set-digest, this path
is not very likely() anymore.

d712a02845 [set-digest] Back to a 3-entry, with different parameters now 
We used to use 4,0,9 for years. Now 3,0,6. It is slightly faster
and shouldn't regress common fonts.  The rationale is that OT
GSUB/GPOS are split by script, so any particular script is not
likely to use more than a few thousands of (consecutive mostly)
glyphs. The exception is CJK of course, but those have less
GSUB/GPOS work.
