The SetGraph method replaces the performance's toolgraph.
HRESULT SetGraph( IDirectMusicGraph* pGraph );
Toolgraph to set. Can be set to NULL to clear the graph from the performance.
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.
Because the graph's reference count is incremented by this method, it is safe to release the original reference.
