Thanks Robert and Paul. I just assumed that a direct GDI call would be
faster, but when I think about it, that can't be true (assuming a
decent OpenGL driver). I did as you suggested and it works very well. Mostly. If I resize the window and make it wide and short, my background gradient maintains it's aspect ratio and blue bars on the sides are soon revealed. Do I need to add code to my event handler to recompute the background scene during resize events?

(after setting an appropriate ClearMask in the camera) I want to have a gradient background and I'm thinking that I could do this easily with the GradientFill() function. I realize I could accomplish the same thing using methods from the osgHud example, but I'm thinking that a GDI call would be faster.
