   2  *   xutils.c - A collection of X-windows utilties for creating WindowMAker
   3  *              DockApps.
   4  *
   5  *     This file contains alot of the lower-level X windows routines. Origins with wmppp
   6  *     (by  Martijn Pieterse (pieterse@xs4all.nl)), but its been hacked up quite a bit
   7  *     and passed on from one new DockApp to the next.
