The draw_path method in backend_cairo.py starts with a check for the number of vertices in the path, and raises an error if the path contains more than 18980 vertices:
def draw_path(self, gc, path, transform, rgbFace=None):
if len(path.vertices) > 18980:
raise ValueError("The Cairo backend can not draw paths longer than 18980 points.")
This was needed in the past when cairo version 1.4.10 / pycairo version 1.4.0 would segfault:
However, we're now at cairo, pycairo version 1.8.8, and I haven't seen any segfaults after removing this check.
Does anybody object if I remove this check from the code?
