Creates a new clipping region by calculating the intersection of the current clipping region and the area described by the Path using the non-zero winding number rule. Open subPaths must be implicitly closed when computing the clipping region without affecting the actual subPaths. The new clipping region replaces the current clipping region....and the area described by the path, using the non-zero winding...and the area described by the path, using the non-zero winding...
