Arguments: stream vertices
Erases (i.e. replaces with the background color or texture) the specified polygon from stream. A polygon is specified by vertices, which should be a sequence (list or vector) of positions. A line is drawn connecting the first vertex with the final vertex.
Contrast with draw-polygon which draws the polygon on stream.
