This is basically a hack for drivers which prevent the mpv DXVA2 decoder glue from working if OpenGL is in fullscreen mode. Since it doesn't add any "hard" new API to the client API, some of the code would be required for a true zero-copy hw decoding pipeline, and sine it isn't too much code after all, this is probably acceptable.
