This is mostly relevant for single-core CPUs where it makes sense to use UI thread render timer. However when such timer is used, we are wasting time in vsync blocking call while the main thread could be doing something more sensible.
This PR adds a mode that offloads the vsync call and the blit to a background thread with high priority.
