2861d65e56 [subset] Update font extents in head table 
When --recalc-bounds option is used the font extents in the head table
need to be updated, but since tables are lazy-loaded by default the
table will not be recompiled and will keep the old value. Force
recompiling the table by adding it to prune_post_subset tables, though
I’m not 100% sure this is the best approach.

45596108e2 (Re)calculate OS/2.usMaxContext value 
The value is only modified in the context of fontBuilder or subset. It will NOT be modified when using ttx.

maxContextCalc.py was copied from https://github.com/googlefonts/ufo2ft/blob/master/Lib/ufo2ft/maxContextCalc.py

Fixes #1191
Fixes #466

00dddb1c32 fixed non retain-gids with no AdvWidthMap behavior 
deltas in VarData[0] are directly look up by GID so compacted
if any deltas are referenced by LsbMap / RsbMap but not used for advance widths, they are moved to the end of VarData[0]

updated expected test result expect_HVVAR.ttx accordingly

5e1dea329b subset HVAR/VVAR with retain-gids 
1. if AdvWidthMap/AdvHeightMap missing, deltas for unused (emptied) glyphs are zeroed
2. If indexMap exists and unused glyph ID <= last used glyph ID, then its major/minor number set to 0/0
3. If indexMap exists and unused glyph ID > last used glyph ID, then its major/minor number set to that of the last used glyph (removed from table)

50dae4cc90 subset: don't error if STAT has no AxisValue tables 
the minimalist STAT table that varLib produces only contains one DesignAxisRecord
for each fvar axis, and has AxisValueCount=0, thus the AxisValueArray offset is None.

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

40ca30a82b [subset] Improve GSUB closure memoize algorithm 
Instead of memoizing the tuple of <lookup-idx,current-glyphs>, use a mapping of
lookup-idx->current-glyphs instead. Saves some work. Speeds up 5%ish on
NotoNastaliqUrdu-Regular.

subset: remove assert to handle HVAR direct mapping 
It looks like this was (at least partially) implemented in
f01c86ca9b

Should fix https://github.com/fonttools/fonttools/issues/1237

I'm still not sure about that "File a bug." when AdvWidthMap is None,
but either LsbMap or RsbMap are not None..

And we still need to add tests for this though.
