flashing using deep mask

[Peter T. Evensen]

This happens both on 2.6.1 and 2.7 on Windows XP.  I haven't tried it on 
Mac yet.  I have a background png that the player is on top of.  The mask 
png is on a different card that is not displayed.

I went with a deep mask so I could switch between two masks without the 
window being closed and reopened, but now I get a lot of flashing when I 
display a png over the background png or a player over a background png 
(and the player doesn't respond to mouse clicks on the controller).

I went back to the one bit masks and now things work (but the window 
disappears and reappears -- lock screen and unlock screen seems to have no 
effect in this case).
