    there are actually a couple of really cool algorithms for this. I
    implemented at least one of them a few years ago. I have the code around
    somewhere, I think. I don't know if the CLIM functions work for
    oddly-shaped polygons; mine do.

I never got around to implementing this.  If you want to donate your
code to the cause, I will gladly accept it.
