     I don't know how up-to-date Ray's work is, but according to this: 
http://www.allegro.cc/manual/view_function.php?_id=1304 it will use the 
global color_map table, or trucolour blender functions. It depends on the 
images you are using You can call set_alpha_blender() to set up truecolour 
blenders. Perhaps if you read that page, you will understand it better than 
I.

  I don't know about this...
