draw black, draw white, leave unchanged (transparent), or invert. The Mac

background. Since the background is usually white, I am arbitrarily
mapping "invert" to "draw black". This entails bitwise math between the
cursor's AND mask and XOR mask:
AND | XOR | Windows cursor pixel
--------------------------------
0 | 0 | black
0 | 1 | white
1 | 0 | transparent
1 | 1 | invert
AND | XOR | Mac image
---------------------
0 | 0 | black (0)
0 | 1 | white (1)
1 | 0 | don't care
1 | 1 | black (0)
AND | XOR | Mac mask
---------------------------
0 | 0 | paint (0)
0 | 1 | paint (0)
1 | 0 | don't paint (1)
1 | 1 | paint (0)
