Remarks
Clients interested to receive notifications associated with the main activities of the overlay manager need to implement this interface and register it using their programming language prefered method. Note that notifications can be received either through this dispinterface or through its custom version _IMcGraphOverlayEvents for clients looking for better performances and supporting vtable binding.
