That's for a very ancient historical reason. The original release of
Ethereal used GtkTree and GtkTreeItem objects (I don't remember the
exact name, but something like that). The decode info was written
directly to the GUI widgets. When I add the proto_tree layer on top of
the GUI widgets, I mimicked the widget classes "just in case". Not a
very good reason, but historical.
