We use GPC (general polygon clipper) in a Cocoa, rule-based publishing app
that positions objects based on their geometry, so GPC is at the heart of
the geometry engine that manipulates and calculates intersections for the
object shapes. GPC is a tiny C library and is extremely fast and robust.
Because it's C and is so small, it was relatively easy to integrate and use.

We have had zero problems with GPC. The only issue we run into is the usual
floating point accuracy issues that are inherent to geometric computation
and are no fault of the library.
