r21285: - Add the new ResizeTableColumnModel and make use of it in TreeVirtual. This
allows the Ldb Browser tree to properly size itself upon initially appearing and upon window resizes. There are still a few problems with it that I need to resolve, including an occasional set of double scrollbars, and making it resize the tree column when the splitter is resized.
