This is great! You and Dr. Geo are the first user of VectorGraphics in Cuis. I'm really happy this is finally happening! Until the VectorGraphics engine is ready to become the main Canvas, I suggest caching the result in a Form, and use that in your morphs. That's what we are doing with TrueType, and it works well.
