Detailed Description
The following class represents a general polygon.Vertices are indexed relative to some vertex array instead of directly represented in the polygon. Note that this polygon has no knowledge of the actual values of the vertices. It only keeps the indices. So it can actually be used both for 3D and 2D polygons.
