gEDA-user: Adding Auto-thermals Was:Re: Thanks a million, and few small questions for a new user

It's the "auto-added thermals" part that's tricky - there's no flag to
say that a thermal is auto-added.

But auto-redoing *all* auto-thermals might work, yes.

If you remove *all* the thermals, you lose track of which net each
polygon is supposed to connect to.  I suppose you could store that
information in the polygon, based on connectivity, at some point.
