a1c6c184ef [mutator] Round lsb for CFF2 fonts as well 
Otherwise head table compilation would fail because of the floating
point side bearing. The advance width is already rounded.

e454e96238 [varLib.builder] Implement building 32bit VarStore 
The full optimizer in varLib.varStore still needs to be updated.
But this pretty much enables building 32bit VarStores, even if they
won't be fully optimal.

ee5ecd19d7 [varLib/glyf] Remove fallback vertical phantom-points code 
I suggested Cosimo add that code in
https://github.com/fonttools/fonttools/pull/1528

Upon further inspection now, that code is unnecessary and even wrong in
cases where different masters have different ascent, because that would
result in encoding variations for vertical phantom points, which will
be then either be unused or double-apply on top of ascent etc.
