Anthony, do you have to do your rotations in real-time or is it possible to pre-
process and cache the rotations for each image?

FYI: I am busy updating the lispbulder-sdl API to take advantage of the new 
finalize methods in the CFFI. So you will be able to create an SDL_Surface and 
have the garbage collector take care of freeing the foreign surface when the 
reference goes out of scope.
