 Hello,

 I'm wondering if anyone has a way of finding out how many colors are
 currently being used on a screen?  I want to make a private colormap
 for my application, and I don't want the screen to go "nuclear" when
 my colormap takes over.  I've found out how to copy x amount of colors
 from the default colormap, but would like to use x as an upper limit.
 ie.  Copy at most x number of used colors from the default colormap,
 but if x number of colors aren't being used, then copy only the ones
 that are being used.

 Any Help would be most welcome.
 Thanks,
 Curt
