   When I try to use draw_lit_sprite or draw_gouraud_sprite in my
program it crashes with a page fault or general protection fault.
RHIDE's Call Frame Traceback window refer's to either of the sprite
drawing functions. I'm using Allegro v3.1. I made a small program
using just the draw_lit_sprite function, and snipped it here incase I
left something important out. If anyone has any suggestions I'd like
to here them. Let me know if more info is needed.
	-Thanks for reading.
