   Masking the way Jimmy Mardell's SQRXZ routine does it or the 5-6 
other masking routines. First sprite is a standard sprite, the 
following is a bit mask. Anything not a one in the mask, XOR's onto 
the screen.

Sprite:
 .db %00111100
 .db %01000010
 .db %10100101
 .db %10011001
 .db %10100101
 .db %01000010
 .db %00111100
 .db 0

 .db %00111100
 .db %01111110
 .db %11111111
 .db %11111111
 .db %11111111
 .db %01111110
 .db %00111100
 .db 0
