	Hi!  This is my first post form my new account!

 	Getting down to business:  Anyone know how the blitter octant bits
decode?  They're called SUD, SUL, and AUL.  They are not laid out sequentially
( i.e. binary values == octant numbers ) and they do not separate quadrants.
Figuring out what octant you happen to be in seems to be a small problem.
