- * The display transformation matrix specifies an affine transformation that
- * should be applied to video frames for correct presentation. It is compatible
- * with the matrices stored in the ISO/IEC 14496-12 container format.
- *
- * The data is a 3x3 matrix represented as a 9-element array:
- *
- * @code{.unparsed}
- *                                  | a b u |

- *                                  | x y w |
- * @endcode
- *
- * All numbers are stored in native endianness, as 16.16 fixed-point values,
- * except for u, v and w, which are stored as 2.30 fixed-point values.
- *
- * The transformation maps a point (p, q) in the source (pre-transformation)
- * frame to the point (p', q') in the destination (post-transformation) frame as
- * follows:
- *
- * @code{.unparsed}
- *               | a b u |
- *   (p, q, 1) . | c d v | = z * (p', q', 1)
- *               | x y w |
- * @endcode
- *
- * The transformation can also be more explicitly written in components as
- * follows:
- *
- * @code{.unparsed}
- *   p' = (a * p + c * q + x) / z;
- *   q' = (b * p + d * q + y) / z;
- *   z  =  u * p + v * q + w

- *         or NaN if the matrix is singular.
