Title: Fix the "ringing" issue when we're throttling the frame rate.

So basically, Qt's QGLWidget will automatically handle swapping the back buffer with the front for us. This isn't desirable when we're throttling the frame rate or outright stopping rendering. Stop Qt from automatically swapping buffers for us, and do it manually instead.
