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.

f6e8577476 [GlyphCoordinates] Revert back from double to float 
We do proper rounding these days, so revert this back.

e9acd9634f [GlyphCoordinates] Store int data as 4byte, not 2byte 
The memory increase is negligible, but means that we don't have to
worry about integer overflows anymore.

8be2f49b84 [GlyphCoordinates] Speed up __imul__() 
Like the recent change to __isub__/__iadd__().

This, as well as the other, change do not handle overflows.
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.

10fe1c2636 Don't write Format for Coverage, ClassDef, Single/Alternate/LigatureSubst 
The format values for those are automatically handled in
postRead/preWrite to choose optimal format.  As such, don't write them
in XML.  Reduces noise.

0faf01d5f1 [otlLib] Generate Value1 / Value2 if respective formats are non-zero 
Previously otlLib was generating None if the values themselves were
empty even if the value format was non-empty.  This happened to work
for compiling to binary since the compiler handles Value=None.

But this was confusing varLib.merger module (as in when building
variable fonts from such otlLib-built master GSUB/GPOS tables, without
roundtripping to OTF/TTF binary first), because in varLib.merger,
a None means "this master doesn't provide that info; skip it"; whereas
in a PairPos table a None as generated by otlLib simply meant "all
values are zero", which is different from "this master doesn't
provide this value".

This fixes that, such that ufo2ft can build variable-font without
saving masters to binary.
