@remarks
This is a specialisation of OverlayElement for 2D elements that contain other
elements. These are also the smallest elements that can be attached directly
to an Overlay.
@remarks
OverlayContainers should be managed using OverlayManager. This class is responsible for
instantiating / deleting elements, and also for accepting new types of element
from plugins etc.
