8af430997d [varLib] Start generating STAT table 
Right now just reflects the axes, and even that with certain limitations:
- AxisOrdering is set to the order axes are defined,
- Name-table entries are not shared with fvar.

28bb992c1f replace int(round(...)) with round(...) 
We don't need to cast to int when using the round function from py23,
as this is a backport of python3's built-in round and thus it returns
an int when called with a single argument.

5eb3cbe2b0 [varLib.mutator] Mutate GPOS 
Cleans up GDEF varstore as well.

What's left:

- In none of the varLib.merger Mergers we handle the CaretValueFormat3. That should be done,
  even though no one uses this,

- GPOS/GSUB FeatureVariations are not applied.  Shouldn't be hard.

- 'rvrn' should be folded into 'ccmp' or some other default feature.

ca7c35900b [mutator] Add instantiateVariableFont public function 
Towards addressing https://github.com/fonttools/fonttools/issues/1070

The new instantiateVariableFont function takes a variable TTFont and a
dictionary of axes locations and returns a static TTFont instance.

The current code modifies the varfont in-place. To adapt it for
generating multiple instances from the same varfont, for now I simply
resorted to making a copy (can be optionally disabled by setting
inplace=True).

Also, replaced print() with log.info().

588f5246c0 [varLib] default to using "name" attribute if "labelname" is missing 
Instead of raising AssertionError when users define custom axes
without explicit `<labelname xml:lang="en">ZZZZ</labelname>` element,
it's better to use the axis' name attribute, and treat it as "en"
language.

For example, if users generate the designspace from SuperPolator,
they can't edit the axis labelname attribute from the UI (or maybe
it's just me that couldn't figure out how to do it).
