Value	Meaning
`moPlay`	/Operation /Play: start the movie playing from the beginning
`moStop`	/Operation /Stop: bring playback to a stop
`moPause`	/Operation /Pause: hold playback at the current frame
`moResume`	/Operation /Resume: carry on from paused playback

Pass a value of this type to THPDFActionBuilder.Movie or to THPDFPage.AddPushButtonWithMovieAction; both fall back on moPlay when the parameter is omitted
The value is written verbatim as the /Operation name of the movie action dictionary, so the string written to the file is Play, Stop, Pause or Resume
Combine with a movie annotation reference to build pushbuttons that serve as playback controls
