[XeTeX] Kerning support

[Adam Twardoch]

BTW, Adobe is aware of the problem. It's unlikely that they will fix it 
in the existing fonts, except by perhaps providing an alternate glyph 
which has different kerning, but in the most recent fonts (Hypatia Sans 
Pro, Arno Pro), they have taken a different approach on this particular 
kerning issue.

If you want to avoid conflicts, you can always rename the entire font. 
After dumping the OTF into XML using FontTools/TTX, you can safely do a 
global search-replace from "Minion" to "MinionWas" or something like that.

Best,
Adam
