Here is a proposed changed set. I saw the classes HierarchicalListMorph, PluggableListMorph, TextModelMorph override the getters, it may be wise to remove these getters and adjust the variable accordingly in the respective initialize methods. I did not do that because I will likely break the image.

Just pushed some updates to make it work again. See examples in class comment in PluggableScrollPane. Play with the halo with the inner morph, see how scrollbars adjust themselves as needed.
