This change splits MediaSceneLoader protocol into SceneLoadable, ImageLoadable and VideoLoadable protocols. PanoramaView, StereoView and StereoViewController are now conform them instead of MediaSceneLoader.
ImageLoadable and VideoLoadable have load() method in its protocol definition (not in protocol extension), so now you can override them.
