22de9ef3d8 [interpolatable] Try harder matching contours 
This improves a bunch of .notdef glyphs.
Only adverse effect is in AdventPro's --glyphs uni2116

b30da672f0 Revert "[interpolatable] Use absolute sqrt area, not signed" 
This reverts commit 772d1f8c7895f9b8844264488bd2b542c4391022.

The new false-positives were not worth it. It degrades
the suggested fix for some fonts, but at least they are
not false-positives.

1cd954d0ff [interpolatable] Tweak magic number 
This removes a lot of false positives, and only seems
to introduce a few false positives for Handjet and Caveat.

e8d212609f [interpolatable] More work and less play

c689bb475a [interpolate] Add some Black Magic 
See comments.

In particular, this reports glyph "intersection" in
Archivo fonts that are broken but otherwise will go
unnoticed.

[interpolatable] Return master indices in addition to master names (#3346) 
[interpolatable] Add master indices to problem reports

More solid than using names to refer back to the master index,
as needed in interpolatablePlot.

7c92b75203 [interpolatable] Use StatisticsControlPen as well 
We use both StatisticsPen and StatisticsControlPen.
If either produced a perfect matching, we accept it.
Otherwise we use the worst score of the two.

This takes care of Kablammo[MORF].ttf and Nabla[EDPT,EHLT].ttf.

Slows down the tool, but I think it's in the right direction.
Further heuristics can be used.
