Well, if OpenGL simple turns every rendering task I ask it to do and 
defers to the hardware, then it isn't much good as a Graphics API.
  If, however, it's intended to simply be a universal API for rendering 
*hardware*, then perhaps it's not appropriate to use it at all for
  simple, uncomplicated, 2D tasks such as those asked of it by Gnu Radio.

But if OpenGL is intended to be an environment for rendering various 
graphical concepts, using whatever optimizations happen to be
  available to it, or not, then it fails.
