[Deprecated as of GSAP 2.0.0; use Power4 instead which is IDENTICAL]
Provides an easeIn, easeOut, and easeInOut with a power (or strength) of 4 which is identical to the Power4 ease. The more power, the more exaggerated the easing effect. Using a numeric approach like Power4 instead of Quint makes experimenting easier and the code reads more intuitively.
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.
