I don't think GDI is buffer-savvy, so there's no way to tell it to draw into the "back" buffer. (10 years ago, when HP made their own graphics cards, we developed a solution for mixing GDI/Xlib with OpenGL, and it was quite flexible. No one else ever implemented such a scheme. As a result, GDI/Xlib rendering into an OpenGL window is unsupported and will produce undefined results.)

If I want to draw something in the client area of the window OSG is rendering into (via Windows GDI calls), would I do this in a preDrawCallback? (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.
