Well, yeah I mean I spent the better part of yesterday tweaking percentage
display values for a sediment legend. Probably not the best use of time, but
at least I can re-use the d.graph script in the future....that is, until I
have to modify the position of the legend on the display, in which case all
the display coordinates have to be re-tweaked. Argh. I'm going to try
Michael's Inkscape suggestion, I guess. 

Although it might be 'fun' giving Hamish's r.reclass/r.support/d.legend -c
fix a go....... ;^)

Thanks for the suggestions, guys,
