GTK has no concept of 2 widgets existing in the same location, and hence
no real notion of layering. There are specific widgets, such as the
canvas, that do support layering, but you could not get the layer
information from widgets that are layered, only from the canvas items
that "hold" them.

how much this might change or have changed in relation to cairo support,
i don't know.
