	Just to find out if I'm right - Allegro clips drawn polygons on a pixel
level right, so even attempting to draw outside of a real graphical bitmap
should be prevented at a source level, correct?
	Also, I had a program which was forever crashing and returning
tracebacks to Allegro's polygon routines, so I presumed I was trying to draw
over or below z=0 or something, but adding the out of BITMAP tests I describe
above, this all ended (as far as I can see so far). Can anyone explain this?
What was I doing wrong?
