+/* This is a special Shell that is designed to use an externally-
+ provided window created by someone else (possibly another process).
+ That other window should have an associated widget of class
+ ExternalClient. The two widgets communicate with each other using
+ ClientMessage events and properties on the external window.
+
+ Ideally this feature should be independent of Emacs. Unfortunately
+ there are lots and lots of specifics that need to be dealt with
+ for this to work properly, and some of them can't conveniently
+ be handled within the widget's methods. Some day the code may
+ be rewritten so that the embedded-widget feature can be used by
+ any application, with appropriate entry points that are called
+ at specific points within the application.
+
+ This feature is similar to the OLE (Object Linking & Embedding)
+ feature provided by MS Windows.

+/* Communication between this shell and the client widget:
+
+ Communication is through ClientMessage events with message_type
+ EXTW_NOTIFY and format 32. Both the shell and the client widget
+ communicate with each other by sending the message to the same
+ window (the "external window" below), and the data.l[0] value is
+ used to determine who sent the message.
+
+ The data is formatted as follows:
+
+ data.l[0] = who sent this message: external_shell_send (0) or
+ external_client_send (1)
+ data.l[1] = message type (see enum en_extw_notify below)
+ data.l[2-4] = data associated with this message
+
+ EventHandler() handles messages from the other side.
+
+ extw_send_notify_3() sends a message to the other side.
+
+ extw_send_geometry_value() is used when an XtWidgetGeometry structure
+ needs to be sent. This is too much data to fit into a
+ ClientMessage, so the data is stored in a property and then
+ extw_send_notify_3() is called.
+
+ extw_get_geometry_value() receives an XtWidgetGeometry structure from a
+ property.
+
+ extw_wait_for_response() is used when a response to a sent message
+ is expected. It looks for a matching event within a
+ particular timeout.
+
+ The particular message types are as follows:
+
+1) extw_notify_init (event_window, event_mask)
+
+ This is sent from the shell to the client after the shell realizes
+ its EmacsFrame widget on the client's "external window". This
+ tells the client that it should start passing along events of the
+ types specified in event_mask. event_window specifies the window
+ of the EmacsFrame widget, which is a child of the client's
+ external window.
+
+ extw_notify_init (client_type)
+
+ When the client receives an extw_notify_init message from the
+ shell, it sends back a message of the same sort specifying the type
+ of the toolkit used by the client (Motif, generic Xt, or Xlib).
+
+2) extw_notify_end ()
+
+ This is sent from the shell to the client when the shell's
+ EmacsFrame widget is destroyed, and tells the client to stop
+ passing events along.
+
+3) extw_notify_qg (result)
+
+ This is sent from the client to the shell when a QueryGeometry
+ request is received on the client. The XtWidgetGeometry structure
+ specified in the QueryGeometry request is passed on in the
+ EXTW_QUERY_GEOMETRY property (of type EXTW_WIDGET_GEOMETRY) on the
+ external window. result is unused.
+
+ In response, the shell passes the QueryGeometry request down the
+ widget tree, and when a response is received, sends a message of
+ type extw_notify_qg back to the client, with result specifying the
+ GeometryResult value. If this value is XtGeometryAlmost, the
+ returned XtWidgetGeometry structure is stored into the same property
+ as above. [BPW is there a possible race condition here?]
+
+4) extw_notify_gm (result)
+
+ A very similar procedure to that for extw_notify_qg is followed
+ when the shell's RootGeometryManager method is called, indicating
+ that a child widget wishes to change the shell's geometry. The
+ XtWidgetGeometry structure is stored in the EXTW_GEOMETRY_MANAGER
+ property.
+
+5) extw_notify_focus_in (), extw_notify_focus_out ()
+
+ These are sent from the client to the shell when the client gains
+ or loses the keyboard focus. It is done this way because Xt
+ maintains its own concept of keyboard focus and only the client
+ knows this information.
