Interesting to see this - I guess this means there's no way to change the 
default background colour to anything other than white then? Was thinking 
this would be a useful setting for the GUI to have - e.g. I much preferred 
the default black background in GRASS <= 5, much easier on the eyes I 

I was also noticing (have been trying out d.histogram while experimenting 
with fonts recently) that it seemed a bit non-intuitive that to display a 
histogram you had to treat it as a map you were displaying and it appeared 
in the Map display Window, with the region setting controls, co-ordinate 
display, etc. all intact. I was thinking it might be more logical and look 
tidier if it appeared in a separate graph display window - the background 
colour could perhaps even be set to be the same as the normal Window 
background colour and it might look very neat then.

Maybe the new GUI does something like this already - I suppose I should be 
looking at it when commenting like this - this is neither a bug report or 
a wish, just a few thoughts I had that I thought I should write down!
