/******************************************************************************
 *
 *	SkEventDispatcher() -	 Event Dispatcher
 *
 * Description:
 *	The event dispatcher performs the following operations:
 *		o while event queue is not empty
 *			- get event from queue
 *			- send event to state machine
 *		  end
 *
 * CAUTION:
 *	The event functions MUST report an error if performing a reinitialization
 *	of the event queue, e.g. performing level Init 0..2 while in dispatcher
 *	call!
 *  ANY OTHER return value delays scheduling the other events in the
 *	queue. In this case the event blocks the queue until
 *  the error condition is cleared!
 *
 * Returns:
 *	The return value error reported by individual event function
