Oh, you're right. I feel a bit of a doofus now :) It's been a year since I looked at the Loop-Blinn paper, I had forgotten they did this. That's not a good excuse, I should've shut up or spent the time to actually look it up before commenting :) Regardless of what they do there, hopefully my general idea comes across clearly from my comment above: create tools that allow users to directly compose/animate convex/concave quadratic curves (which render trivially on a GPU as triangles with a fragment shader), and leave dealing with overlaps to the user + tools.
