Ideally, the user would assign a polygone to a net, but maybe that would 
be a lot of work to implement.

If the user drew a trace to a poly, would that force that polygon to 
always be on that net,
thus allowing code in the 'o' section to always know what net the 
polygone was, and thereby
allowing thermals to be turned on in the correct way.

Also, I'm still hoping someone can point me to a certain function or 
area in a certain file
because I looked and couldn't find what looked like code that would do it.
(Perhaps there's a document someplace that I should read that gives me 
an overview of how things work and what files do what.)

THanks very much,
