Avoid advancing animations outside the animation "tick"
We have logic to prevent animations from starting in the middle of an animation as a result of a previously slow frame. This was based on current time, not the animation driver time and would cause severe jumping when custom animation drivers were being used. Also, this logic would trigger multiple animation runs per frame, which is very bad for performance, so this change introduces a threshold of 50ms to compensate for that. 50ms because that is triplebuffer limit.
