1d148b10c5 [varLib] Start implementing optimal IUP solution 
Not optimal right now, since first and last point are always included.
Also rather slow.  Takes about 12s for NotoSansArabic, and saves just
one percent in gvar size with a tolerance of 0.5 font units.

use logging.warning() instead of deprecated logging.warn() 
functionality is identical, the latter is deprecated:

61670fc652 Use logging module for these warnings 
Not sure if warnings module was used intentionally here, but the
messages looked odd compared to other FontTools messages.

dbc54a2429 [varLib.models] Mark VariationModel.interpolateFromDeltasAndScalars static 
This correctly reflects that all we need to interpolate is deltas and
scalars.

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...

e8571ee5e0 [varLib] Only use sparse points (ala IUP encoding) if cheaper

0fa41c14b9 [varLib] Check all master and instance locations are valid 
Ie. they don't specify any unknown axes, and location is within
axis minimum/maximum.  We also allow master / instance locations
to not specify some axes, and we fill in the axis default for those.
