caryclark 8016b264ce interpolation of coincidence must be local to a single span
Pathops makes up intersections that it doesn't detect directly,
but do exist. For instance, if a is coincident with b, and
b is coincident with c, then for where they overlap
a is coincident with c.

The intersections are made up in different ways. In a few
places, the t values that are detected are interpolated to
guess the t values that represent invented intersections.

The interpolated t is not necessarily linear, but a linear
guess is good enough if the invented t lies between known
t values.

Additionally, improve debugging.

This passes the extended release test suite and additionally
passes the first 17 levels in the tiger test suite;
previously, path ops passed 7 levels.

The tiger suite is composed of 37 levels in increasing
complexity, described by about 300K tests.
