Yes - I'd forgotten I'd already taken care of this. If you look at the
implementation of QCanvasItem.setCanvas() in qcanvas.sip, ownership is
transferred to C++ if the item is now allocated to a canvas and
transferred back to Python if it is not now allocated to a canvas.
Obviously, once ownership is back with Python the C++ dtor will get
called when the Python object is garbage collected.
