The background is the same as the normal desktop, so we blur and desaturate it to clearly show that it's not the normal system state. To do so, we don't use standard ClutterEffects, to avoid the FBO indirection. Instead, we take advantage of MetaBackgroundActor support for GLSL code and paint the shaded background texture directly. https://bugzilla.gnome.org/show_bug.cgi?id=682536
