* Rewrite surface handles in curves, so that Booleans beyond
the first don't screw up.
* If an intersection curve is identical to an existing curve
(as happens when faces are coincident), take the piecewise
linearization of the existing curve; this stops us from
screwing up when different shells are pwl'd at different
chord tols.
* Hook up the plane faces again.
* Remove coincident (parallel or anti-parallel) edges from the
coincident-face edge lists when doing Booleans; those may
happen if two faces are coincident with ours.
* Miscellaneous bugfixes.
It doesn't seem to screw up very much now, although tangent edges
(and insufficient pwl resolution) may still cause problems.
