Upon closer inspection, it turns out that the PiecewiseAffineTransform
*does* have an inverse implemented.  It was the "+" operator causing
the problem.


Still, I have found cases now where I get invalid answers for valid-
seeming sets of coordinates.  I'm investigating further, but I think I
have a solution to your problem.
