[AS3/AS2 only] Normally, all transformations (scale, rotation, and position) are based on the DisplayObject's registration point (most often its upper left corner), but TransformAroundCenter allows you to make the 2D transformations occur around the DisplayObject's center. Keep in mind, though, that Flash doesn't factor in any masks when determining the DisplayObject's center.

If you define an x or y value in the transformAroundCenter object, it will correspond to the center which makes it easy to position (as opposed to having to figure out where the original registration point should tween to). If you prefer to define the x/y in relation to the original registration point, do so outside the transformAroundCenter object, like:

TweenLite.to(mc, 3, {x:50, y:40, transformAroundCenter:{scale:0.5, rotation:30}});

import com.greensock.plugins.TransformAroundCenterPlugin; 
TweenPlugin.activate([TransformAroundCenterPlugin]); //activation is permanent in the SWF, so this line only needs to be run once.
TweenLite.to(mc, 1, {transformAroundCenter:{scale:1.5, rotation:150}});
