12 * 3x3 matrix.
13 * DirectX-compliant, ie row-column order, ie m[Row][Col].
14 * Same as:
15 * m11 m12 m13 first row.
16 * m21 m22 m23 second row.
17 * m31 m32 m33 third row.
18 * Stored in memory as m11 m12 m13 m21...
19 *
20 * Multiplication rules:
21 *
22 * [x'y'z'] = [xyz][M]
23 *
24 * x' = x*m11 + y*m21 + z*m31
25 * y' = x*m12 + y*m22 + z*m32
26 * z' = x*m13 + y*m23 + z*m33

28 * \class Matrix3x3
