Regarding your previous message, I presume you are referring to transforming a rectangular pixel map into an arbitrary quadrilateral? It would be easy enough to write a C function to do this but it would be slow. Writing accelerated (MMX) code for this type of routine would be time-consuming, and it wouldn't achieve the same level of speedup that I got with the smoothscale function.
