Eto support in all Rhinos

I see a lot of new developments for Rhino, but only a few “insiders” have the chance to really get into these. The developers do not have the time to document their work or write some examples which may help the “semi-professionals” to use all that beautiful stuff. Community on idle… if everything is put into plug-ins.

Believe me, we’re working on improving that situation
