PolygonMorph is more like M3Exp01Morph, M3Exp02Morph and M3Exp03Morph. But these also don't work well yet. Damage areas are not reported correctly and morphContainsPoint: doesn't work either. The VectorGraphicsPasteUpMorph was just a hack to let you play with vector graphics drawing, but I guess it is time to clean it up, make it usable, and integrate it. Then it will make sense to start building things like PolygonMorph in a clean style. Please give me a few days to work on this.
