Hi,

Next revision the pvmouse protocol.  It is quite different now, I've 
decided to move to a model with one message per updated value, simliar 
to the linux input layer.  There isn't a "mouse move" message any more. 
  A mouse move event will be three messages now: one to update X, one to 
update Y and a third sync message to mark the end of the message block. 
  That should be *alot* easier to extend in the future.

Header file is attached.  Comments are welcome.

thanks,
   Gerd
