Too late! It's already on sourceforge:
  http://sourceforge.net/projects/goocanvas

There's a mailing list there if you want to use that, but the cairo list
is OK with me as well.

No, not yet. I've been pretty happy with cvs to be honest (I don't
really do much branching & merging).

I've just added a simple demo item in demo/demo-item.[hc]

Unfortunately there's quite a bit of boilerplate code in the simple
item. Maybe we could avoid this somehow in future, but I'm not sure the
best way of doing that.
