Okay, this sounds like a good idea, and the results are indeed a vast 
improvement!

I don't think pixman needs to expose explicit controls over parameters 
of a specific algorithm like this function does (it sets individual 
rates for x and y.)  There are lots ways to sample and filter the 
source, and walking across a regular sampling grid might not always be 
the best way to go about it.
