It might be a good idea anyway, but it turns out this doesn't help on iphone.. I could be
doing something wrong though. The best solution I have found is to use a plain black
Default.png and disable the status bar in the Info.plist. I think maybe creating the
opengl context starts it with a black screen so there is always an ugly break between
Default.png and my programs drawing.
