Curently in OpenGL mode we dont have any logo displayed.
We need to display the 3D rotating OpenGL logo ( cf old tests )
and the SDLlogo, same as the SDLEngine right now.
OpenGL Engine should probably inherit from SDLEngine the same way as for Surfaces and Video class hierarchy.
Since the Engine is hidden from the user, we should be careful to use the proper one in each Video Renderer case ...
