howto autowrap line in gnomecanvas text

[Bruno Coudoin <bcoudoin anfora fr>]

Hi,

what's the best way to do text wrapping (go to newline) using the gnome canvas.

With I18N, you can't know the text size so I would like to be sure to contain 
it in an invisible pre-defined area.
I tested the clipping feature but at that time it did not autowrap.
