Batch up draws into triangle fans as large as possible when drawing convex
edge AA polys, so we minimize state changes and GL calls. This requires
querying GL for the maximum number of fragment uniforms. It also makes the
shader generator produce custom shaders for the number of relevant edges.
This gives a ~5X speedup on the "Shapes" SampleApp.
