Detailed Description
The csPolygonClipper class can be used for clipping any polygon against any other convex polygon.The clipper object should be used, if possible, for many polygons (for example, a 3D sprite can initialize a clipper object then clip all of its triangle against it at once) as the initialization of clipper polygon involves some (although not too expensive) calculations. The clipping polygon *should* be convex since the routine does not expect any line to intersect the edge of clipping polygon more than twice.
