I thought this would be really easy to do in Performer, but I can't
find a way to do it. I'd like to put a series of small channels
at the top of the screen, overlaying the main full-screen channel.
Since the main channel is an out-the-window view for a flight simulator,
I don't want to entirely block the view -- instead I'd like to have
the smaller channels semi-transparent. The game "Certain Impact"
has a moving map display that uses this technique.
I've looked at changing the pfState and the setGState for the
channels, but it seems to me that they'd make the actual scene
database become semi-transparent, then that would be overlayed on
the main channel. What I'd like is the channel to be rendered normally
but then *overlayed transparently* over the main channel.
Any suggestions? And thanks!
