I would advise against investing too much effort in this solution. While it certainly should work for OpenGL, all rendering should be done through painters so that alternative rendering backends (POV-ray, etc) can have the same features. Clipping the primitives through GL won't have an effect on the other backends, which is why I've added the extra code to actually draw the clipped primitives in the painter.
