/**
* The <i>Shadow Sync Sample Box</i> table provides an optional set of sync
* samples that can be used when seeking or for similar purposes. In normal
* forward play they are ignored.
*
* Each entry in the Shadow Sync Table consists of a pair of sample numbers. The
* first entry (shadowedSampleNumber) indicates the number of the sample that a
* shadow sync will be defined for. This should always be a non-sync sample
* (e.g. a frame difference). The second sample number (syncSampleNumber)
* indicates the sample number of the sync sample (i.e. key frame) that can be
* used when there is a random access at, or before, the shadowedSampleNumber.
*
* The shadow sync samples are normally placed in an area of the track that is
* not presented during normal play (edited out by means of an edit list),
* though this is not a requirement. The shadow sync table can be ignored and
* the track will play (and seek) correctly if it is ignored (though perhaps not
* optimally).
*
* The Shadow Sync Sample replaces, not augments, the sample that it shadows
* (i.e. the next sample sent is shadowedSampleNumber+1). The shadow sync sample
* is treated as if it occurred at the time of the sample it shadows, having the
* duration of the sample it shadows.
*
* Hinting and transmission might become more complex if a shadow sample is used
* also as part of normal playback, or is used more than once as a shadow. In
* this case the hint track might need separate shadow syncs, all of which can
* get their media data from the one shadow sync in the media track, to allow
* for the different time-stamps etc. needed in their headers.
