You can use the channel drawcallback to draw what you want.
Don't make a call to the pfDraw() function and then you just
have a clear screen. Setup a 2D ortho viewport and draw what you want.
Look in the code examples that give examples for HUD of how to do
it. They are in the archives for this mailing list.
