Instead of trying to guess about which motion events are extraneous, queue up all events until we process a frame. This allows us to look ahead and reliably compress consecutive sequence of motion events. clutter-main.c: Feed received events to the stage for queueing. Remove old compression code. Remove clutter_get_motion_events_frequency() clutter_set_motion_events_frequency() clutter-stage.c: Keep a queue of pending events. clutter-master-clock.c: Add processng of queued events to the clock source dispatch function. http://bugzilla.openedhand.com/show_bug.cgi?id=1637 Signed-off-by: Emmanuele Bassi <ebassi@linux.intel.com>
