0ed2df3f22 [varLib.interpolate_layout] Import designspace-loading logic from varLib 
When varLib was updated for avar table, this was not.  Share code such
that they don't get out of sync again.  All of this to be made into
proper API some time...

81498e5baf [varLib] Fix bug with recombining PairPosClass2 subtables that don't 
Ouch.  I have no idea why I made two separate if's to begin with, but the
continue should have also been aligned with the inner block...

Fixes root cause of https://github.com/fonttools/fonttools/issues/914
but now we hit an unimplemented feature there...

3db5be2195 [gvar] Remove GlyphCoordinates.__abs__() 
It's not wel-defined, as abs typically is supposed to return a scalar...

Also combine the tolerance-check with the zero-check in varLib.

e46f94950c Change GlyphCoordinates.__bool__() semantics... 
...to match those of other iterables.

I confused myself once already by having "if not delta" where delta was a list,
not GlyphCoordinates...

0fa41c14b9 [varLib] Check all master and instance locations are valid

axis minimum/maximum.  We also allow master / instance locations
to not specify some axes, and we fill in the axis default for those.

86549315fd [varLib.merger] Fix recombining of multiple PairPosFormat2 subtables

43060a0d08 [varLib] Do not encode gvar deltas if all values smaller than tolerance 
Tolerance is set to .5 by default.  Most designspaces never hit this since
for most, all deltas are integers anyway.  Moreover, all such detas will
round to zero anyway.

c8b2088162 Revert "[varLib.merger] only insert merged PairPosFormat1 subtable if at least one font has one" 
This reverts commit d83c2fb2090fa58f94fdf32d1aa2d2d8665cec05.

This is wrong. We should insert if and only iff there's at least one of the
fonts with a Format1. Yours doesn't look at all fonts. Since this one is not a
bugfix but improvement, I'll fix it separately.

[varLib.merger] avoid reusing the same Class2Record (mutable) objects 
Class2Record is mutable, hence doing `[rec2] * l.Class2Count` produces a list containing multiple references to the same instance. When later on we do the interpolation, modifying one would modify them all.
We need to instantiate distinct objects.
