Both, X and Windows query the absolute mouse position here and the NS
code should do the same (just that I don't have any idea what the direct
NS equivalent for XQueryPointer/GetCursorPos is - it should be somehwere
hidden in ns_mouse_position's

      position = [[view window] mouseLocationOutsideOfEventStream];
      position = [view convertPoint: position fromView: nil];

but I'm too lazy to figure that out).  last_mouse_motion_x/_y are
conceptually reserved for note_mouse_movement and should not be used for
anything else (IMHO).
