Behdad Esfahbod c87b317f0e [util] Add hb-ot-shape-closure tool 
Computes all the glyphs that may be generated given a font and
set of Unicode characters.

The order of the Unicode characters is irrelevant.

Sample output:

behdad:util 0$ ./hb-ot-shape-closure Doulos\ SIL\ Regular.ttf f
f f_f

behdad:util 0$ ./hb-ot-shape-closure Doulos\ SIL\ Regular.ttf i
i

behdad:util 0$ ./hb-ot-shape-closure Doulos\ SIL\ Regular.ttf fi

Behdad Esfahbod 5df809b655 [GSUB/GPOS] Remove context_length 
The spec doesn't say contextual matching should be done this way,
and AOTS doesn't do it either.  It was inherited from old HarfBuzz.
Remove it.

Behdad Esfahbod 2097951110 [util] Change default font size of hb-view to 256 
Most common usecase of hb-view is to test rendering of short words for
testing / inspection.  Not having to type "--font-size 150" each time
isn't such a bad idea...

Behdad Esfahbod 18c06e189b [Indic] Add Uniscribe bug feature for dotted circle 
For dotted-circle independent clusters, Uniscribe does no Reph shaping
for the exact sequence Ra+Halant+25CC.  Which also is the only possible
sequence with 25CC at the end.

Behdad Esfahbod 5f131d3226 [GSUB/GPOS/Indic] Apply GSUB/GPOS within syllables only 
This does not apply to the context matchings.

This regresses tests right now.  And we are not sure whether this is
the right thing to do for GPOS.  But we'll figure out.
