The Qt debug runtime prints a bogus warning on the console if you haven't called makeCurrent since the last time you called swapBuffers. This presumably means something if you're using QGLWidget the "regular" way, but in our multi-threaded use case is harmless since we never call doneCurrent in the rendering thread.
