That's exactly what I didn't want to happen in this test (not mentioning that
none of the frameworks we have does this, but it's the general concept of
caching that I wanted to make sure doesn't happen) because it'd be pretty
funny to try to test tessellation and intersection detection by allowing
frameworks to skip intersection detection. But like I said, my tests are
completely irrelevant for this discussion since they had a completely
different goal.

Unfortunately this is also a case we have to make work and work well.
