[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.

[GSUB] Further adjustments to mark-attachment vs ligation interaction

The d1d69ec52e
change broke Kannada badly,
since it was ligating consonants, pushing matra out, and then ligating
with the matra. Adjust for that. See comments.

[GSUB] Don't set new lig_id on mark ligatures
...
If two marks form a ligature, retain their previous lig_id, such that
the mark ligature can attach to ligature components...
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=676343
In fact, I noticed that we should not let ligatures form between glyphs
coming from different components of a previous ligature. For example,
if the sequence is: LAM,SHADDA,LAM,FATHA,HEH, the LAM,LAM,HEH form a
ligature, putting SHADDA and FATHA next to eachother. However, it would
be wrong to ligate them. Uniscribe has this bug also.

And use it to speed up the hotspot by checking coverage directly in
