This is useful for autoplay for example. With autoplay, it is necessary to wait until the scene graph is fully set up. This signal is emitted once the QML item node is ready. So, inside a connected slot, the pipeline's state can be set to PLAYING to automatically start playback as soon as the QML script is loaded. https://bugzilla.gnome.org/show_bug.cgi?id=786246
