Petr, please look over these changes. What needed to be done to  
properly render the colorbar for all the demos looks strange to me (a  
gnuplot bug?). Specifically, when y2 has tic labels, I had to set both  
yrange and y2range. Ditto for x2.

Jaroslav, everything seems to work (for me), so I've push it.
