b63b8ceb8b [GlyphCoordinates] Remove internal dual representation 
Always store coordinates as float. Convert to int in __getitem__() if is whole.

This changes observed values. But we never made any guarantees so that's fine.

Going to fix that now.

8c59d4be0c [subset] Improve PairPosFormat2 subsetting 
This does two things:

1. Intersect subsetter glyphset with the table's Coverage before
   passing to ClassDef1 for subsetting.  Anything that doesn't
   get past Coverage wouldn't ever get to ClassDef1,

2. Never reuse class0 of ClassDef2.  There's unspoken assumption
   that ClassDef2's class0 is never used for actual kerning, since
   that's the unbounded "every other glyph" class.  Previously our
   ClassDef subsetter was reusing class0 if "every other glyph"
   happened to become empty because of the subset glyphset.  Don't
   do that for PairPos's ClassDef2.  As a result of this assumption,
   don't keep a PairPosClass2 subtable if only ClassDef2's class0
   survived subsetting.

Would be good to add tests for both.
