37dd59120b [varLib] Allow merging sparse ClassDefs 
This is mainly meant for GDEF.GlyphClassDefs, but implementation is on the
ClassDefs type.  What can possibly go wrong...  Seriously though, this is
pretty much always what is desired.  To be embraced by more type mergers
down the road.

c50b1b9ef6 [varLib] Allow sparse masters in GPOS merging / others 
VariationMerger is updated such that it accepts None list members
in .mergeThings, and switches to correct sub-model.  This means,
it technically supports more than just a few masters missing GPOS.
This allows for some within-GPOS differences to also be handled,
though that's not well-studied or complete.

The symmetry is desired.

7ee81c8821 [varLib] Take total bounding box into account when resolving model 
Umm. Not sure how useful this is, but helps with cases where there
were not masters on extremes and people expected this to work.
Happens in Higher-Order Interpolation since the axis extremes
are not interesting.

Fixes https://github.com/googlei18n/fontmake/issues/473

Test case (in case someone wants to add it to test suite!):

mutator: round to closest width class 
this is the mapping between the half of each percentage intervals and
the associated usWidthClass:

{56.25: 1,
 68.75: 2,
 81.25: 3,
 93.75: 4,
 106.25: 5,
 118.75: 6,
 137.5: 7,
 175.0: 8}

Notice how wdth=80 (in the adjusted test case) will fall in width class
3, instead of 4, because it is < 81.25, thus closer to the nominal 75
than to 87.5.
