/**
* Describes the information to obtain facial expression.
*
* Description
*
* Callers should request a time equal to the predicted display time for the rendered frame. The system will employ appropriate modeling to provide expressions for this time.
*
* Valid Usage (Implicit)
*
*
* - The {@link FBFaceTracking XR_FB_face_tracking} extension must be enabled prior to using {@link XrFaceExpressionInfoFB}
* - {@code type} must be {@link FBFaceTracking#XR_TYPE_FACE_EXPRESSION_INFO_FB TYPE_FACE_EXPRESSION_INFO_FB}
* - {@code next} must be {@code NULL} or a valid pointer to the next structure in a structure chain
*
*
* See Also
