/// Updates every tweens with a delta time ang handles the tween life-cycles
/// automatically. If a tween is finished, it will be removed from the
/// manager. The delta time represents the elapsed time between now and the
/// last update call. Each tween or timeline manages its local time, and adds
/// this delta to its local time to update itself.
/// <p/>
/// Slow motion, fast motion and backward play can be easily achieved by
/// tweaking this delta time. Multiply it by -1 to play the animation
/// backward, or by 0.5 to play it twice slower than its normal speed.
