And the numerical stuff (bezier intersections or what they are) really
needs to be C++.  Scheme is nice for glue code, but you should then have
a Bezier smob or similar and have logical operators at the Scheme level
that are then implemented in C++.

Nobody ever wants to touch that once it delivers the right results:
there is nothing tweakable in there.
