Certainly. The idea of a separate algorithm library would allow people
to create their own GUI wrapper much more easily. I assume most people
would prefer to start their own, than to dive into the old code of
Planner, unfortunately.

But making it modern would be great.

Are you sure? What about GooCanvas? It's a 2D drawing widget based on
Cairo. Sounds exactly like what you need there.
