IVMRImageCompositor9 interface

The IVMRImageCompositor9 interface is implemented by the default compositor for the Video Mixing Renderer Filter 9 (VMR-9). It must also be implemented by any plug-in compositor that an application provides for the VMR-9. The VMR-9 calls the methods on this interface to inform the compositor that it should composite the incoming video frames into a single output frame. Applications do not use this interface.
