Subject: Pipe Throttle Update Event to EventManager, client --> ScenePresence
 --> EventManager,  so that modules can know when throttles are updated.  The
 event contains no client specific data to preserve the possibility of
 'multiple clients' and you must still call
 ControllingClient.GetThrottlesPacked(f) to see what the throttles actually
 are once the event fires.  Hook EventManager.OnUpdateThrottle to
 GetTextureModule.
