Consider periodically sending frames at low frequency

[chrisduerr]

Currently when nothing has rendered in a frame the rendering is stalled indefinitely until additional damage is done. Since some applications might rely on receiving frames it would likely be safer to periodically send frame requests to applications.

Currently I haven't encountered any application that would necessitate this and it would also likely affect energy usage negatively. So this seems to be somewhat optional.

This shouldn't really be necessary. Never encountered any issues with it.
