IVMRImageCompositor interface

The IVMRImageCompositor interface is implemented by the default compositor for the Video Mixing Renderer Filter 7 (VMR-7). It must also be implemented by any plug-in compositor that an application provides for the VMR-7. The VMR-7 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.

For the VMR-9, use the IVMRImageCompositor9 interface.
