What does this do? Is this necessary? Do we call this at all? Frame by frame? Per FrameBuffer?

I believe it should be called per update per frame buffer. Default seems to be the whole window. glViewport seems to be useful for multiple point of views. This includes split screen (for games), and multiple perspectives (for CAD programs).
