/*
* A few notes on the delay transform properties...
*
* The kCanEverDelayTransform prop is independent of any parents/children.
* It means this particular node must always update its transform in response
* to a plTransformMsg. It is intended for objects with physics, because they
* need to be up-to-date before the simulationMgr updates the physical world.
*
* The kDelayedTransformEval prop is for nodes that are free of physics. (So no
* physical descendants either). If the property is set, we won't update our
* transform until AFTER the simulationMgr does its work.
*
* When we attach a child that can't delay its eval (at the moment), we recurse
* up to the root, turning off the kDelayedTransformEval prop as we go. When we
* remove such a child, we check if that child was the only reason we weren't
* delaying our transform. If so, we update ourself and tell our parent to check.
*
* BTW: The POINT of all this is that when we update our l2w transforms because
* we're animated, and then we update AGAIN after a parent node of ours involved
* in physics gets a slight nudge, the first update becomes pointless. The
* delay prop bookkeeping keeps us from doing the wasted calculations. And since
* nearly all bones on the avatar are in this exact situation, it's worth doing.
