[Therion] Mining symbols?

[Christian Rößler (Roessler)]

Hallo everyone,

I remember faintly that some years ago, when I used Therion for a bit (but 
did not progress further as centreline output) there was a discussion 
about mining symbols for Therion. I lost these Mails; archive says 2007. I 
think this would broaden the applicability of Therion to mine explorers.

Has, by any chance, work progressed in this field, as I could not find 
anything via web/wiki search? If not, how can I help? Are there other 
miners here who would like mining symbol sets, too?

Until then, is there a possibility I can insert a free hand draw of, say, 
a shaft symbol (which would be more of an area)?

Best regards, Christian
