</span>Sigh. It looks ok when used that way because the process makes a SketchMorph which draws by use of blending. Which is pretty much exactly what I said, though possibly rather long-windedly. Scratch has to use paint. Well, it could of course be changed to use blend but as previously explained that has a risk of messing up old projects and costing too much time on slower machines.<br>

OK, I give up.<br>
