 *     xrMsgBoxInfo   * msgInfo;
 *     INT32            message;
 *     INT8           * data;
 *
 *   Description:
 *   -----------
 *     This is the message box manager.  It takes an xrMessageBox info 
 *     structure and creates a panel with any combination of a static
 *     raster, static text, and push button editor.  The message box 
 *     exits when the user presses a keyboard key, presses a push button
 *     or the panel timer (if set) times out.
 *
 *
 *   Inputs:
 *   ------
 *     msgInfo = This is a pointer to an xrMessageBox information
 *               structure.  It contains the information used to
 *               create the editors used in the message box and the
 *               message box itself.
 *
 *     message = Contains either MSG_EDIT, or MSG_SIZE.
 *
 *     data    = A pointer to an xrEvent structure or a rectangle
 *               structure depending on the message sent.
 *
 * 
 *   Outputs:
 *   -------
 *     TRUE    = Returned if the dialog with the user is successful.
 *
 *     FALSE   = Returned if the message box could not be created or
 *               sized.
 *
 *     data    = With MSG_NEW
