I've never really considered caching in GooCanvas before (noone has
requested it, and I've been trying to finish other stuff).

Since a canvas can be very large, you can't really cache all items all
the time. So I guess there should be something like three options for
caching for each item - None, Always and When Visible.

I don't think it would be too hard to add.
