The function draw-polygon
draws a polygon using alternating x and y values in points as the vertices. When closed is true the edge from the last vertex to the first to be drawn. When filled is true a filled, closed polygon is drawn; closed is ignored if filled is true.
The transform, foreground, background, operation, thickness, scale-thickness, dashed, dash, line-end-style, line-joint-style, mask, pattern, shape-mode and compositing-mode from port's graphics-state are all used, unless overridden in args. Additionally on X11/Motif only, stipple is used.
fill-rule specifies how overlapping regions are filled. Possible values are :even-odd
and :winding
