EasingAround is a class to simplify even more very basic tweens. The idea behind this class is to provide a means to create a tween that starts and ends at the same value.

If your regular Easing function [from 1 to 10] behaves as follows:

   1 . . . . 5 . . . . 10

then, an EasingAround function with the same parameters behaves as:

   1 . .5. . 10 . .5. . 1

in the same amount of time.

These equations come in handy when we want to create some quick animation -like button rollovers- with the shortest code, without having to "chain" two consecutive tweens.

Example (rollover the icon or click the stage to tween):

This is the code for the rollover tween:

This class contains only the easing equations and should be compatible with any AS3 tween engine out there (e.g. Tweener) or with code that uses fl.motion.easing.* or fl.transitions.easing.*

The functions are named as follows:

EasingAround.easeNone

EasingAround.easeInQuad
EasingAround.easeOutQuad
EasingAround.easeInOutQuad
EasingAround.easeOutInQuad

EasingAround.easeInCubic
EasingAround.easeOutCubic
EasingAround.easeInOutCubic
EasingAround.easeOutInCubic

etc...

Note: EasingAround uses the original easing equations by Robert Penner.
