+      <description summary="client is ready to be shown">
+        Tell the server that this client is ready to be shown. The server
+        will delay presentation during start-up until all shell clients are
+        ready to be shown, and will display a black screen instead.
+        This gives the client an oppurtunity to set up and configure several
+        surfaces into a coherent interface.
+
+        The client that binds to this interface must send this request, otherwise
+        they may stall the compositor unnecessarily.
+
+        If this request is called after the compositor has already finished
+        start-up, no operation is performed.

+        request, the server will immediately send a configure event with
+        the dimensions the client should use to cover the entire output.
+
+        The surface must have a "desktop" surface role, as supported by
+        libweston-desktop.
+
+        Only a single surface may be the background for any output. If a
+        background surface already exists, a protocol error is raised.

+        Set the surface to act as a panel of an output. The 'edge' argument
+        says what edge of the output the surface will be anchored to.
+        After this request, the server will send a configure event with the
+        correponding width/height that the client should use, and 0 for the
+        other dimension. E.g. if the edge is 'top', the width will be the
+        output's width, and the height will be 0.
+
+        The surface must have a "desktop" surface role, as supported by
+        libweston-desktop.
+
+        The compositor will take the panel's window geometry into account when
+        positioning other windows, so the panels are not covered.
+
+        XXX: What happens if e.g. both top and left are used at the same time?
+        Who gets to have the corner?
+
+        Only a single surface may be the panel for an output's edge. If a
+        surface already exists on an edge, a protocol error is raised.
