I see that you use the fancy ".diff" format to post patches. I would like
to do that too. I have patched these files of Allegro 3.9.32:
allegro.h
asmdefs.inc
i386.s

I use it actually to cast shadows in an 8 bit color mode. Colors 128-255
contain half bright copies of colors 0-127, and whenever an object is
casting a shadow I draw OR 128 and am done with it. Efficiency is much an
issue so a colorblender is out of question for me.
