Note, that when looking up an IVisualPart for a given visual in the map, it is required to walk up the visual hierarchy until a registered visual is found, because an IVisualPart only has to register its "main" visual (i.e. the one returned by IVisualPart.getVisual()) at the visual-part-map, but potential children visuals do not have to be registered.
