nc seal breaks simplify

This test has nearly coincident lines that are missorted.
The underlying bug is caused when a pair of curves
are coincident when reduced to line segments, but the
end points aren't detected.

The error was generated by running nanobench over all svg
sample data with the distance field patch installed.
