Reserved.

## Overview

This field must be `0`.

> Important:  A new flag has been added to the flags field of the `QTVRPanoSampleAtom` data structure. This flag controls how panoramas wrap horizontally. If `kQTVRPanoFlagAlwaysWrap` is set, then the panorama wraps horizontally, regardless of the number of degrees in the panorama. If the flag is not set, then the panorama wraps only when the panorama range is 360 degrees. This is the default behavior.
