Does anybody know (I'm sure someone does) how to blit a bitmap with opengl? Rendering a texture mapped quad is not what I'm looking for. I want total control over where the bitmap is placed on the screen. No stretching should be applied to the bitmap.

You can use the glDrawPixels function to accomplish this and you use glRasterPos* to specify where on the screen it is rendered. You have just as much "total control" over where the bitmap is placed using this method as using a texture-mapped quad.
