ok, now that I can see that toggling the mouse coordinates on/off  
results in a change to the window height.

As we cannot be sure that the window size returned by x11 includes the  
extension or not, I'm now strongly in favor of gnuplot *not* extending  
the window when displaying the coordinates ... or being able to tell  
gnuplot not to.
