right now i am using
glClearColor( 0.7, 0.9, 1.0, 0.0 );
to just set the entire background to a light blue. i would like it to be a gradient though. i cannot simply create a quad and change the color with the vertices because my image is rotate-able, and i dont want the background to rotate with it.
or is there a way to set up rotation so that everything moves except a quad?
