[gtk+/wip/ebassi/gsk-renderer: 502/545] Add details to css render nodes

[Emmanuele Bassi <ebassi src gnome org>]

    Add details to css render nodes
    
    Give all nodes the same detail about the owner widget.
    This reveals that every GtkCssCustomGadget gets a
    DrawGadgetContents node, even if their draw_func is NULL.
    We may want to come up with a better solution for that.
