 * Use
 *  Sends out an internal broadcast message.  The routine constructs a
 *  Message_StraylightInternal block and sends it out via win_broadcast.
 *  The parameters should be as for the entries in the appropriate
 *  structure, in order (i.e one for glass_DELETEWINDOW, two for
 *  glass_DELETEICON).
 *
 * Parameters
 *  glass_intMessage type == the message type.  This is used to decide
 *    how many and what type of parameters to accept.
