ttFont: allow to build glyph order without post nor cmap, just maxp.numGlyphs 
could be useful to read in incomplete sfnt fonts e.g. containing only GPOS or GSUB tables

0ecf5c5c94 [varLib.models] Refine modeling one last time 
In a523a697164a4 I changed the model such that when computing master
supports and we hit another master, cut the box in one dimension only,
to avoid interferring with other master.  The axis to cut against was
chosen as axis that minimizes volume loss.  That was fine in a sense,
but missed a great amount of information resulting from relative
positioning of the two masters.  As such, it could not distinguish
between the following two situations:

behdad:fonttools 0 (master*)$ ./fonttools varLib.models 0,0 0,1 1,0 1,1 .5,.5 .55,.75
Sorted locations:
[{},
 {'A': 1.0},
 {'B': 1.0},
 {'A': 1.0, 'B': 1.0},
 {'A': 0.5, 'B': 0.5},
 {'A': 0.55, 'B': 0.75}]
Supports:
[{},
 {'A': (0, 1.0, 1.0)},
 {'B': (0, 1.0, 1.0)},
 {'A': (0, 1.0, 1.0), 'B': (0, 1.0, 1.0)},
 {'A': (0, 0.5, 1.0), 'B': (0, 0.5, 1.0)},
 {'A': (0, 0.55, 1.0), 'B': (0.5, 0.75, 1.0)}]
behdad:fonttools 0 (02616ab...)$ ./fonttools varLib.models 0,0 0,1 1,0 1,1 .5,.5 .75,.55
Sorted locations:

 {'A': 1.0, 'B': 1.0},

Supports:
[{},
 {'A': (0, 1.0, 1.0)},
 {'B': (0, 1.0, 1.0)},
 {'A': (0, 1.0, 1.0), 'B': (0, 1.0, 1.0)},
 {'A': (0, 0.5, 1.0), 'B': (0, 0.5, 1.0)},
 {'A': (0, 0.75, 1.0), 'B': (0.5, 0.55, 1.0)}]

Check the last line. In both cases the box was cut against the second axis.
After this change, we get:

behdad:fonttools 0 (master)$ ./fonttools varLib.models 0,0 0,1 1,0 1,1 .5,.5 .55,.75

 {'A': (0.5, 0.75, 1.0), 'B': (0, 0.55, 1.0)}]

Just draw the boxes on a piece of napkin and convince yourself that this
is a good change.

If the ratios are equal, we cut against the first axis in the axisOrder:

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.

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.

a523a69716 [varLib.models] Improve model 
When adding a master and computing its support, when hitting another master,
we don't need to limit our box in every direction; we just need to limit in
one so we don't hit the older master with our support. Implement heuristic
that takes the first axis that minimizes the area loss.

This is not perfect, but a good improvement.
