Several obtuse reasons for setting RETAIN=0 in a draw widget
come immediately to mind:

   (1) You are using object graphics in the window, in which
       case RETAIN should *always* be set to 0.

   (2) You know how screwy colors can be and you wish to
       protect the colors associated with this application
       by "restoring" your colors every time the widget is
