I can never remember what all the inks do without experimenting, but I 
think there is one that does exactly what you describe -- reverses the 
color. On mousedown, set the ink, on mouseup set the ink back to 
"srcCopy" (the default ink.) If you do that, you won't have to poll 
fields or keep track of anything.
