  * This class receives local touch input events and forwards them to the remote host.
  * A queue of MotionEvents is built up and then either transmitted to the remote host if one of its
  * remote gesture handler methods is called (such as onScroll) or it is cleared if the current
  * stream of events does not represent a remote gesture.
