I don't believe so. Anything that uses the BLIT_LOOP macro will do at 
least one iteration, so that rules out h <= 0. w <= is a little 
trickyer. Some functions will work with a zero width, some won't.

In any case, you'll have to either check for that condition in the 
assembly code, or in the C code. I'd prefer to have it done in the C code :)
