<DL>
<DD>When called it performs three primary tasks:
 <UL>
 <LI>(1) Checks to see if rate direction has changed - if so calls the rateDirectionChanged method
 <LI>(2) Calls the transformMatrix method which the subclass defines
 <LI>(3) If doConstraintBoundsTesting is true does bounds testing of the target within
 the enclosing space and notifies of any collisions of the target with the space's sides.
 </UL>
 Once these tasks are performed the target's matrix is set to the transformed matrix
 through calling the setTargetMatrix with the transformed matrix.<DD><DL>

 method is called) the action has reached one of its specified constraint conditions

 if the Action has an Actionable actor.<DD><DL>
