   Has anyone ever managed to create transparent windows (or widgets)
   using the Xtoolkit?  It says in the Intrinsics Programming Manual
   that the background attribute of a window can be transparent, but
   nowhere is it explained how to accomplish that.

Well, sort of. I've set the background to none (NULL?). When the
widget came up whatever was behind the widget appeared in place of the
background. I said "Oh, great. Its transparent" then moved the window.
The background remained the same (i.e. it didn't get update to reflect
the new obscured display.). I was using MWM and my own widget.
