 * Authors:  Jim Fulton, MIT X Consortium,
 *           based on a version by Douglas Young, Prentice Hall
 * This widget is based on the Tree widget described on pages 397-419 of
 * Douglas Young's book "The X Window System, Programming and Applications
 * with Xt OSF/Motif Edition."  The layout code has been rewritten to use
 * additional blank space to make the structure of the graph easier to see
 * as well as to support vertical trees.
