I believe these problem are all known. I don't know if there is an  
easy fix or not, but as I'm trying to improve the gnuplot's back-end  
support of figure/axes properties, I'll look at this as well. I'll  
follow up once I understand the problem better (if anyone else has  
looked into the details please comment).

btw, I like the tongue-n-cheek quote by Bach.
