86549315fd [varLib.merger] Fix recombining of multiple PairPosFormat2 subtables 
Gosh!  This is the kind of thinko that doesn't happen with less dynamic languages...

Good one hour of debugging at TYPO Labs. Glad this one is fixed finally!

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.

9798c30d57 [varLib.merger] Really recombine multiple PairPosFormat2 subtables... 
Fixup for 49d311550c29f7501dd4bc91cb24074e3d607b77

Previous try was completely dropping the ParPosFormat2 subtables. Ouch!

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.

[varLib.builder] fix calculation of VarData.NumShorts 
The problem was that `break` statement: we stopped searching for SHORT columns in each delta set after finding the first, but rows can contain more than one in any order.

fb0c60cd2c [varLib.merge] Fix tests 
Set Coverage.Format to 1. This is rather arbitrary, which is exactly
why Coverage.Format doesn't make sense and should not have been
exposed to begin with.

[designspace] if elements not defined, don't set key/value pair in returned dict 
According to https://github.com/LettError/designSpaceDocument

> Not all values might be required by all applications.

So if any of 'elements', 'sources' or 'instances' is missing, the dictionary
returned by designspace.load will not contain those keys.
