05f95f0f58 [otBase] Try ExtensionLookup if other offset-overflow methods fail 
If offset overflow happens other than between Lookup and SubTable, or
within SubTable, then we don't know how to fix it currently.  Now we
try to put that lookup in an Extension lookup anyway, since that will
isolate it and sharing with other lookups won't happen, hopefully
avoiding the overflow.

This is really a bandaid... What we want is the 99proof branch to
be finished and replace our current packing algorithm.

use otRound when rounding visual coordinates or deltas 
So we now round towards +Infinity in:

- floatToFixed (which fully examplify that quotes from OT spec)
- psCharStrings: when packing floats as fixed 16.16
- t2CharStringPen: when rounding coordinates and advance widths
- subset: when rounding advance widths to compute average
- TupleVariation: rounding gvar deltas
- _g_l_y_f: when rounding coordinates: both in GlyphComponent.{x,y}
  and for GlyphCoordinates.toInt()
- _h_m_t_x: for rounding horiz/vert metrics
- varLib: rounding horiz metrics and deltas

[glyf] ensure GlyphCoordinates never overflow 
in _checkFloat (used whenever we're about to update the inner array) we check whether the value exceeds a short integer, and if so we convert the array to floats.
Also, we make sure we call __setitem__ (which in turn calls _checkFloat) instead of updating the inner array directly in the rest of the math methods.

ttFont: allow to build glyph order without post nor cmap, just maxp.numGlyphs

795f2f95fb [otBase] Fix sharing of tables referred to by different offset sizes 
When an offset refers to a table, we keep the size of the offset to
the referred-to table. When sharing tables, we were ignoring this,
which could result in a long offset being written out as a short, or
vice versa.  Fix it by not sharing such tables. This is not optimal
but fixes the bug.

Bug has been there forever.

d3a6a4e9e4 Don't fail during ValueRecord copy if src has more items 
We drop hinting by simply changing ValueFormat, without cleaning
up the actual ValueRecords. This was causing failure at this assert
if font was subsetted without hinting and then passed to mutator.
