The SetGraph method assigns a toolgraph to the segment.
HRESULT SetGraph( IDirectMusicGraph* pGraph );
Toolgraph pointer. Can be set to NULL to clear the segment graph.
If the method succeeds, the return value is S_OK.
If it fails, the method can return E_POINTER.
Any messages flowing through tools in the current toolgraph are deleted.
The graph's reference count is incremented, so it is safe to release the original reference.
