5132bbe411 [symfont] Remove glyph perimeter from GlyphStatistics 
It's not technically statistics the same way the other properties are, and
we have a separate pen for it, so remove. Goal is to turn GlyphStatistics
into a pen.

Also remove perimeter from interpolatable.py contour characteristics vector.
Shouldn't be needed, given all the stats we already include.

da4b81e9ab Add momentsPen as generated by symfont:printPen() 
To be moved to proper place soon.

Using this in interpolatable.py makes the core of the computation over an
order of magnitude faster.

c8a82dcfee [symfont] Protect against math errors 
Note that because our contours can overlap arbitrarily, our variance can end up

223ecc6453 Revert "[symfont] Make sure variance is never negative (float precision issue)" 
This reverts commit 5c025c6a03cca2ebe3390671a81aaca28492e71c.

Investigating why I'm seeing non-negligible negative variance.

don't use sys.exit(...) inside main(), but only under if __name__ == "__main__" 
The convention is that sys.exit(...) is called only if a module is run as a script,
and that main() entry points use return statements to report exit codes: 0 (or None)
for successful execution, or any non-zero integer for errors.

E.g. see the console scripts generated when installing with pip.

1d28abdb65 [gvar] Rename GlyphVariation to TupleVariation 
In the OpenType 1.8 specification, this is called TupleVariation
so let's be consistent with the spec. (The initial implementation
in fonttools pre-dates OpenType 1.8).
