		implements CLSID_FilterGraph.

	- At least, the following interfaces should be implemented:

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