[woff2_test] use bytes instead of unicode literals in struct format strings 
This is for compatiblity with Python older than 2.7.7.

See https://bugs.python.org/issue19099

> Issue #19099: The struct module now supports Unicode format strings.

explicitly require 'head' table in TTFont.save() 
it's implicitly required anyway, e.g. by ttx's ttCompile, maxp's recalc, OS/2 compile, etc.

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.

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

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

45c266441e [feaLib] Add tests for zero values in contextual positioning 
Specifically, contextual positioning statements with in-line single
positioning rules, in horizontal and in vertical contexts. For these
test cases, feaLib and makeotf produce the exact same output.

7c67e4a63d [feaLib] Compile zero values to different formats based on context 
If a zero value appears in a SinglePos statement, feaLib continues to
produce ValueRecords of format 0. But if a zero value appears in a
PairPos statement inside a horizontal compilation context, feaLib now
produces ValueRecords of format 4. Likewise, if a zero value appears
in a PairPos statement inside a vertical compilation context, feaLib
now produces ValueRecords of format 8.

The OpenType Feature Syntax specification is completely silent about this,
but the new behavior matches that of makeotf.

790c93d5cf [feaLib] Test compilation of zero values in SinglePos statements 
In context of SinglePos, makeotf compiles zero values to value records
of format 0. feaLib already does the same, but it's good to have tests
to make sure that this doesn't accidentally change.
