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.
(This used to be commit c3c93ad36a9e850865aa8b09e319a77441243b01)
