Add Proper Vsync and/or frame limiting support about xl-engine HOT 2 CLOSED

Vsync now works correctly, however I still need to thread the input to avoid noticeable input latency.

from xl-engine.

Adaptive Vsync is enabled when available (which means that synchronization is ignored if the frame takes too long to render).

An accurate framerate limiter has been added as an alterative, which can be run at any framerate. The user should set this to a multiple of the refresh rate - but low enough that the system can hit it reliably. This drastically reduces tearing (especially during rapid screen movement) while having almost no affect on input latency (since OS messages/inputs are still queued while waiting). Obviously it doesn't remove tearing completely like vsync but is a good compromise since it helps a lot and does not have the drastic affect on game responsiveness that vsync can have.
