I was mostly thinking about the graphics, but yes, one can extend it to
other dimensions also.

I don't have much experiences with eda suites, is there a list
somewhere of the mistakes, or can we make such a list, so we can avoid
them ?

I'd be fine with lgpl.

Is this the thin/thick symbol discussion again ?
Previous such discussions didn't bear fruit, how can we make it
happen this time ?
What are people using now, what common threads of thoughts can we
find in different solutions ?
And yes, the thin thing must be supported.
