easeOutCubic( t ) {

		return 1 - Math.pow( 1 - t, 3 );

	}
Computes the easing out cubic function for ease out effect in animation.

@private
@param {number} t - The absolute progress of the animation in the bound of `0` (beginning of the) and `1` (ending of animation).
@returns {number} Result of easing out cubic at time `t`.
