Make flatten_bezier iterative

Added patch to make flatten_bezier iterative.
Should be correct, but no guarantees I didn't break something in the process of
conversion.

Since the bug doesn't appear for me, can you try if this helps (and is still
correct)?
Probably pretty bad for performance, since stack is so much faster, but since
stack seems limited...
