    gesturestylus: Use GtkEventControllerEvent events to track changes
    
    We use gtk_gesture_get_last_event() underneath at places that need to
    work during ::proximity emission. Since GtkGesture only tracks events
    while there are button/touch presses involved, this is not going to
    bring the right result there.
    
    Use gtk_event_controller_get_current_event() consistently inside,
    which always pokes at the event being handled (which is the correct
    intent here).
