/* nautilus_background_canvas_group_supplant_root_class is used internally by
NautilusBackground to change the class of a canvas in order to customize its
background drawing. The reason we have to change the class of a canvas group is
that the cleanest way to hook into the code that erases the canvas is to be the
root canvas group. But the canvas class creates the root object and doesn't allow
it to be destroyed, so we change the class of the root object in place.
A future version of GnomeCanvas may allow a nicer way of hooking in to the code
obviating this fn.
This fn is private to NautilusBackground.
