The provided test case in a form suitable for cairo-test-suite
Thanks for that excellent test case, Zoltan. I hacked it into something
suitable for cairo-test-suite and I can confirm that this still dies from the
failed assertion on current git/master. And nope, sorry, no quick suggestions
for a fix (but I am not sure about ignoring the clip for extents->clip->path ==
NULL is the right thing unless something somewhere already intersects the drawn
boxes with the clip's boxes).
Are you ok with the following header being added to your test case?
