That is great. The default setting of 14 for the title font gives me 
title which goes beyond the top of the canvas, though. Setting it to 13 
solves that.

Very cool.

Seeing that it is possible to save the legend as a vector eps file 
(which I can then nicely convert to other vector formats for further 
layouting) makes me wonder whether it would be possible to do the same 
for the entire map.

At present the map is a raster image stored in the dispmon* files. Thus 
it cannot be exported to a vector format. Would it be feasible to 
actually change this system, so that the map is displayed in a vector 
format in the canvas, just as the legend ? Or is this too slow in tcl ? 
Too complicated trying to deal with geographical coordinates ?
