General fixes:
=============
- Instead of forming clusters immediately, only do it if we are reversing
the text. We'd need a separate bit to indicate cluster start then.
- Right now, BTW, for non-native direction runs, we get the cluster wrong...
Should do min(input-glyphs.cluster)
- Fix TT 'kern' on/off and GPOS interaction (move kerning before GPOS)
- Do proper rounding when scaling from font space?
