persistent graphic objects internally and store them in an internal
container to prevent their early destruction. This makes it possible to use
the returned URL of the graphic object in any way (e.g. insert it into a
property map) without needing to store it immediatly at an object that
resolves the graphic object from the passed URL and thus prevents it from
being destroyed.
