[Therion] Legend symbols

Hello, I really like the way therion can automatically create the legend, and it plots only the symbols you have used. However, I have just noticed that if I have sometimes plotted "waterflow" (for example) as a Line symbol and sometimes as a Point symbol, there will be two boxes in the legend, both called "waterflow" but with slightly different water flow symbols in them. Perhaps, for symbols that could be drawn as a point or line, the ledge needs to only make ne entry for them? I think there might also be a similar issue if you use the point or area symbol for say sand, "sand" will appear twice in the legend, with 2 slightly differnt pictures. Thanks, Jenny
