drawDibTransformedPolygon

Definition: drawDibTransformedPolygon(a32Dib dib_dest, a32Dib dib_src, sequence pol_dst, sequence pol_src)
Description: Draws the region inside polygon pol_src from bitmap dib_src on bitmap dib_dest, transformed to the polygon with coordinates pol_dst.
Comments: pol_dst and pol_src look like {{x1, y1}, {x2, y2}, ...} and need to have an equal number of points.
If you pass an empty sequence {} for pol_dst or pol_src, then the bounding rectangle of that bitmap is used.
Both polygons must be convex.
