Correct.  Modifying the Curve directly would bypass the invariant
checks.  For now the best procedure is to copy out the sequence of
Curves you are interested in, modify then, and then replace them.

We do need a path editing abstraction which can ensure the invariants
while providing a nicer API, however.  I still haven't come up with
anything satisfactory yet though.
