Provides an easeIn, easeOut, and easeInOut with a power (or strength) of 4 which is identical to Quint and Strong but with a more intuitive name. The more power, the more exaggerated the easing effect. Using a numeric approach like this in the name makes experimenting easier.
This is one of the eases that is natively accelerated in TweenLite and TweenMax. All of the "Power" eases and their counterparts (Linear (0), Quad (1), Cubic (2), Quart (3), Quint (4), and Strong (4)) are accelerated.
Example usage:
TweenLite.to(obj, 1, {x:100, ease:Power4.easeOut});
