776e1ce132 [cffLib.specializer] Fix CFF argument stack overflow 
The code was always merging at least two blends, which was causing
stack-overflow with a test font of ours. Move the overflow check
earlier to catch that.

40b525c1e3 [removeOverlaps] Fix CFF CharString width 
The width argument of `T2CharStringPen()` is inserted directly into the
CharString program, so it must be relative to Private.nominalWidthX, but
CharString.width is a calculated absolute value.

Some implementations, notably Adobe’s, will use the width from the CFF
CharString instead of the one from hmtx table.

07351d12e6 Fix visual artefacts with partial L2 instancing 
Closes #3634

To produce inferred deltas that will be correct given OpenType's gvar
semantics, fontTool's IUP optimisation module checks the equality of
some points. However, this happens before the points are rounded,
whereas the point comparison that happens at runtime will occur after
the points are rounded (as is necessary to serialise glyf), which leads
to diverging semantics and so diverging and incorrect implied deltas.

This leads to significant visual artefacts, e.g. where large deltas that
should be inferred based on previous values are instead interpreted as 0
at runtime.

I suspect this has gone undetected as the subsetter normally works with
rounded points; in the rarer case that partial VF instancing is
occurring with a different default position, however, varLib.instancer
will calculate and apply the relevant deltas to the font's original
coordinates to effect the new default position, which leads to unrounded
points in memory. This commit ensures that we round directly before
optimising (but still after calculating `glyf` metrics, for backward
compatibility).
