+/**
+ * 3x3 matrix.
+ * DirectX-compliant, ie row-column order, ie m[Row][Col].
+ * Same as:
+ * m11 m12 m13 first row.
+ * m21 m22 m23 second row.
+ * m31 m32 m33 third row.
+ * Stored in memory as m11 m12 m13 m21...
+ *
+ * Multiplication rules:
+ *
+ * [x'y'z'] = [xyz][M]
+ *
+ * x' = x*m11 + y*m21 + z*m31
+ * y' = x*m12 + y*m22 + z*m32
+ * z' = x*m13 + y*m23 + z*m33
+ *
+ * \class Matrix3x3
+ * \author Pierre Terdiman
+ * \version 1.0
