<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.
</description>
</request>
<request name="set_background">
<description summary="set surface as output's background">
Set the surface to act as the background of an output. After this
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.

<request name="set_panel">
<description summary="set surface as panel">
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.

Asks the compositor to make a toplevel to become the current/focued
window for window management purposes.
See xdg_toplevel.set_app_id from the xdg-shell protocol for a
description app_id.
If multiple toplevels have the same app_id, the result is unspecified.
XXX: Do we need feedback to say it didn't work? (e.g. client does
not exist)
