Hi, i would like to know if there is any simple way for detecting if two
polygons (2D polygons, can be concave) intersects (and detect the cliping
region) with the capi library. I have found algorithms for cliping  polygons
(like Weiler-Atherton algorithm), if someone has a Lisp implementation of
any of theese algorithms, it wolud be very useful for me. Tank you very
much.

Rafa.
