d533e8bd39 [StatisticsControlPen] Fix uninitialized variable 
An open contour was hitting this because _startingPoint wasn't
set.

This was dropped in the previous commit.

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.
