graphics-state parameters passed as keyword arguments.

While the exact results are host-specific, it is intended that a filled rectangle does not include the lines (x = x+width) and (y = y+height ) while a non-filled rectangle does.

The graphics-state parameters transform, foreground, background, operation, thickness, scale-thickness, dashed, dash, line-joint-style , mask, pattern, shape-mode and compositing-mode are used. Additionally on X11/Motif only, stipple is used.
