I don't think this functionality belongs in pixman at all. Computing the
number of subsamples is essentially a performance/quality tradeoff, which
is something that cairo and other clients need to make for themselves. In
general, pixman is not the place for heuristics; its API should be
predictable and explicit.
So, NACK from me on this patch.
