That is what I suspected.  I can imagine the nightmare that might be. 
 There would be nothing worse than having some small difference between 
systems throw the whole paradigm out of whack.  And now that I look at 
the VMS switch in gplt_x11.c I see that it is, in fact, much of the core 
algorithm that is different, not just the graphics support.  Just a pipe 
dream, I guess.
