[mutter/wip/wayland-stacking: 5/7] Adds a --display-server option

[Robert Bragg <rbragg src gnome org>]

commit 264b2f5b68616432058f460f753dff124b0c65df
Author: Robert Bragg <robert linux intel com>
Date:   Fri May 3 00:57:28 2013 +0100

    Adds a --display-server option
    
    This adds a --display-server option to mutter so mutter no longer runs
    as a classic X compositor with an output window mapped on the X
    Composite Overlay Window and in fact no longer assumes it is running
    directly under X. In this mode Mutter will itself launch a headless X
    server and display output is handled with Clutter and Cogl. This enables
    running Mutter nested as an application within an X session and will
    also enable Mutter to directly manage the display hardware itself.
