This structure describes how to handle film grain synthesis in video
for specific codecs. Must be present on every frame where film grain is
meant to be synthesised for correct presentation.
@note The struct must be allocated with av_film_grain_params_alloc() and
its size is not a part of the public ABI.
Additional fields may be added both here and in any structure included.
If a codec's film grain structure differs slightly over another
codec's, fields within may change meaning depending on the type.
