Marios Patsias <m DOT patsias AT cytanet DOT com DOT cy> was overheard mumbling
incoherently about HELP with Allegro (draw_sprite function):

>I use the Allegro draw_sprite() function for displaying bitmaps, but 
>the bitmap isn't masked as it should be (according to the documentation),
>and the blank pixel of it owerwrite the background.
>Is there anything that I should know before using this function.
>Note: The bitmap is a memory bitmap defined in a grabber .DAT file.

Are you sure that the areas that should be transparent are color 0
(palette index 0, not necessarily black)?  Many graphics programs
don't give you complete control over the palette order.
