/* DistTourSprite moves and rotates a sprite representing
   a client from another machine. 

   It is very similar to TourSprite, but doesn't
   send its moves/rotations to the server.

   The methods defined here are called by the TourWatcher, in 
   response to move/rotation messages received from the 
   server.
