	  The client should really have no say over what the DeviceEventController
          does with regards to event delivery as such the 'syncronous' flag is redundant.

	  The 'global' flag is now useless as XEVIE is no longer maintained. As such
	  the DeviceEventController will not recieve any device events from applications
	  not participating.

	  The only possibly useful flag is 'preemptive'. However all keyboard events are
	  sent as pre-emptive from gail so its debateable whether even this flag is really
	  in-use.
