I don't really know that much about the internals of the canvas, but
I've been using libgnomecanvasmm2 for several of my projects and
haven't seen any bugs yet.
Among other things, I've used it for a game where I store a lot of
pixbufs on the canvas on top of each other. Works fine. The only
problem is that it's a bit slow on redrawing the whole thing when
completely obscured by another window. But otherwise there's no

I recall a huge discussion on gnome-devel long before Gnome 2.0 was
released about the possible future direction of the canvas. Also,
wasn't someone looking into merging it into GTK+? It doesn't seem to
be on the schedule on www.gtk.org/plan/ Did everyone lose interest?
Perhaps the discussion need a kickstart?
