    LayoutManager: Remove broken startup animation
    
    It doesn't make sense to animate blindly a MetaBackgroundActor, given that
    it shows the content of _XROOTPMAP_ID, so if gnome-settings-daemon is fast
    we're animating the configured background, not the plymouth screen. And anyway
    it would be animated on top of the standard MetaBackgroundActor...
    It makes even less sense now that mutter renders the background on its own
    (and blocks the first paint cycle until the background image is ready)
    We need to do something better here, but for now, remove this.
