The problem is, it doesn't anti-alias, so you have to do some tricks to
make it work. I believe set ray samples to 1,1 for example, but then of
course, it doesn't anti-alias. Also rayhittest() doesn't take a spread
option, so for the blurred reflections, you have to write your own
spreading. It's not easy :(
