why would anyone think you could do that? if someone thought, "i want to uniformly sample a subset of x-y space, i guess i'll instead ill sample in r-theta space and then use the nonlinear transformation x = r cos theta and y = r sin theta to sample uniformly."
i would assume someone didnt even know what uniform meant if they did that.
and graphics people are so insane about perf, they arent going to just start doing sqrt over and over. they are going to rejection sample anyway because it just 2 fmas
