/* f.send_msg test
 *
 *"An application can specify a message for MWM to send the application when
 * the user invokes the f.send_msg function.  The application places a
 * _MOTIF_WM_MESSAGES atom on the WM_PROTOCOLS property for the window.  The
 * application also places an atom on the _MOTIF_WM_MESSAGES property.  When the
 * f.send_msg function is invoked with this atom as the argument, MWM send the
 * application a ClientMessage.  The application can use XmAddWMProtocols() to
 * place a _MOTIF_WM_MESSAGES atom on the WM_PROTOCOLS property, and it can use
 * XmAddProtocolCallback to place an atom on the _MOTIF_WM_MESSAGES property and
 * associate it with a routine to be called when MWM sends the ClientMessage."
