                implements CLSID_FilterGraph.

        - At least, the following interfaces should be implemented:

        IUnknown
                + IPersist
                + IDispatch
                + IFilterGraph - IGraphBuilder - IFilterGraph2
                + IGraphVersion
                + IDispatch - IMediaControl
                + IPersist - IMediaFilter
                + IDispatch - IMediaEvent - IMediaEventEx
                + IMediaEventSink
                + IDispatch - IMediaPosition
                + IMediaSeeking
                + IDispatch - IBasicVideo[2] (pass to a renderer)
                + IDispatch - IBasicAudio (pass to a renderer)
                + IDispatch - IVideoWindow  (pass to a renderer)
        (following interfaces are not implemented)
                + IMarshal
                + IFilterMapper2 - IFilterMapper3
                FIXME - Are there any missing interfaces???
