The TrackEditState class implements the corresponding data structure of the Movie Toolbox.
The Movie Toolbox provides functions that allow you to capture and restore the edit state
of a track. As with the functions that manipulate a movie's edit state, you can manage a
track's edit states in order to implement an undo capability for track editing.
For example, you can capture a track's edit state before performing an editing operation,
such as a cut, and later restore the old state.
This structure specifies the track edit state for an operation.
Your application obtains a track edit state identifier when you create the edit state by
calling the NewTrackEditState function (described on page 2-269 of
Inside Macintosh: QuickTime).
