The code is no worse than the rest of the stuff in there, so we might as 
well add it.  Someday we'll figure out a reasonable architecture for all 
of this compositing code and regularize it.  But, for now, I think just 
hacking the heck out of it is about as good as we can manage.

Note that on the mach64, you might want to run at 16bpp as that can be 
reasonably accelerated, even if the results aren't as pretty.  I'm hoping 
to get some time to accelerate the compositing operations using the 
hardware; let me know if you have an interest in working on that (that 
would only work at 16bpp).

If you can add autodetection code to the configure.in file for 
WORKING_UNALIGNED_INT, I can go ahead and apply the patch.

Oh, if you can make the dst writes go through one of your fancy macros, 
the results will be faster when dst is in the frame buffer.
