yes, wallpaper could be easily done without support from the library.
i still don't have an exactly clear idea how the qml loading would be
handled by the new shell, but whatever does qml loading for
containment (probably a containment subclass? that should be discussed
shortly as well) should load its own qml and then the wallpaper qml
and put it in a lower z-order.

as the current, the lifecycle of the qml wallpaper should depend if
the view wants a wallpaper at all (easier on scenegraph since we have
at most one view per thing)
