I don't think we'll be including a canvas widget in GTK+ for GTK+-2.8;
just getting Cairo, redone themes, maybe printing support will be plenty
of 2.8. And GTK+-2.10 won't be until ~2006. 

It's unlikely we'd include GnomeCanvas verbatim ... a canvas widget in
GTK+ would likely be aligned very closely with Cairo, rather than 
being an interface on top of a 

So I'd say you should pick based on what is available now, not what
might be available in 1.5-2 years. Try out GnomeCanvas, DiaCanvas, etc.
See what works well. Consider at least the possibility of writing
a "canvas" yourself. I'm never entirely sure that a canvas helps
once you reach a certain level of complexity. Trying to sync your
internal data to the canvas object tree can be almost as hard as
just drawing/picking based on your internal data.
