  46  * This widget is based on the Tree widget described on pages 397-419 of
  47  * Douglas Young's book "The X Window System, Programming and Applications
  48  * with Xt OSF/Motif Edition."  The layout code has been rewritten to use
  49  * additional blank space to make the structure of the graph easier to see
  50  * as well as to support vertical trees.
