CR: Add thumbnail in Helix dbus-server

Synopsis:

    Add thumbnail feature for Helix dbus-server by capturing image from the rendering gdk window.

      

Overview:

    Add thumbnail feature for Helix dbus-server by capturing image from the rendering gdk window.

        > creat another player in Helix dbus-server, it will render to a gdk window

        > capture an image from the gdk window's pixel buffer

        > we want the gdk window in the background; because there may be some GUI or playback in the foreground.

          when the gdk window is in the background, its pixel buffer will be invalid.

          add the gdk window to composite could help us to overcome this.
