Hi Noah,
Indeed, this is a potentially a very useful body of code.
I have several implementations, some which flatten and others that do not, but the non-flattening cases are not always totally reliable. This can be a very hard problem to solve. I have a number of test cases that I can throw at the code that might show up problems - I'll be glad to give your code a whirl. Which algorithm did you employ?
Thanks for doing this and making it available so cheaply (!) It's something that I've always thought should be part of NSBezierPath as standard (especially as Core Graphics must have the code in there already to calculate clipping path intersections).
