Using a bool seems for me the best option.
Handle layer polarity involves also to draw items (tracks, flashes and 
polygons) in the gerber data file order (this is not exactly the case 
currrently),
and draw them in memory using polarity parameter before ORed the final 
result with other gerber data files if any to see the entire data on 
screen like now.
(As i wrote in my previous mail).

Thanks, Dick, for your work.
