libpolyclipping-dev - 6.4.2-8+b1 main

The Clipper library performs polygon clipping, polygon offsetting and polyline
offsetting. All four boolean clipping operations are supported - intersection,
union, difference and exclusive-or. Also, there are no restrictions on the
types of polygons that can be clipped - they can have holes, be
self-intersecting, have coincident edges etc.

These are the files needed for compiling programs with libpolyclipping.
