The "working area" thing was around long before I started, and it
might have just been a naive way to make the software simpler.

Aside from any negative-coordinate issues (which we could/should
probably just fix), the other reason that came up the first time we
discussed this was the problem of "losing track" of your perspective,
or the board itself.  Consider a gschem startup where there's no
visible sense of scale, and the first part you add is a tiny dot...

Yes, this is a minor point, but I don't think we got past it either.
Having an unbounded "zoom out" makes it difficult to do something
simple like show a reasonable scroll bar, for example.  Little things
like that.
