device->update

device ->update_pointed: event

Update the device<-pointed chain to represent all graphicals displayed on the device for which event is in the event_area. Graphicals that are deleted from the chain are send an area_exit event. Graphicals that are added to the chain are send an area_enter event. If on or more of the mouse-buttons are down, these events are area_cancel and area_resume.
