Comment (by elypter):

 MouseEvent.which and MouseEvent.metaKey could reveal hardware specific
 buttons like ö
 WheelEvent.deltaY and WheelEvent.deltaZ could reveal hardware because not
 every device has them.

 not revealing the pointing device at all is difficult if the movement can
 be tracked. touchscreens jump mouses move pen tablets move or jump and
 touchpads and balls move,stop,move. x/y could only be revealed if the
 cursor isnt moving but i dont know if this could be circumventd with tons
 of hidden mouse over events.
