4eebdf4f0d [statisticsPen] Add StatisticsControlPen 
It uses the control box and discrete statistics instead
of using the Green's theorem.

Works better on contours that have no area.

Surprisingly, this seems to be slower than StatisticsPen.
Perhaps because MomentsPen is Cythonized.

21864fc26a [statisticsPen] Another bandaid 
Sigh. I'm probably doing something wrong but I don't understand.

0d28975708 [statisticsPen] If area=0, use control-box samples 
Slower because we have to remember the nodes, but
more accurate.  Particularly useful in varfonts
where they intentionally collapse a contour to
zero area.

d43617c2e3 [statisticsPen] If area is zero, report controlbox meanX/Y 
Before we were returning all zeros.

This reduces false-positives in interpolatable.py

Three new members are also added to the pen:
sumNodesX, sumNodesY, numNodes.

290c3333f9 [statisticsPen] Variance and standard-deviation are non-negative 
I don't know why I get negative values there, but add an
abs() for now.

This fixes varLib.interpolatable false-negatives with
NotoSansEthiopean's `koa.eth` glyph.

ttGlyphPen: drop implied before rounding, allow not to round at all 
We want to be able to compute implied oncurves both before coordinates have been rounded to integer and afterwards.
Also when ufo2ft builds interpolatable master TTFs, we want to turn off the rounding so that varLib can call dropImpliedOnCurvePoints on the un-rounded coordinates, so we need an option to disable rounding the coordinates in the ttGlyphPens

add filter pen that explicitly emits closing line when lastPt != movePt 
it can be useful when comparing two paths and testing whether then contain the same number/types of segments

prevent cython.compiled raise AttributeError if cython not properly installed 
It's possible sometimes that 'import cython' does not fail but then 'cython.compiled' raises AttributeError.
It actually happened in our internal production environment...
