+/**
+ * A 4x4 matrix. This is an OpenGl style matrix (column major) meaning
+ * that the vector {m[0][0],m[0][1],m[0][2],m[0][3]} is the first column of
+ * the matrix , the same as what you get if you transform {1,0,0,0}.
+ * This makes it easy to transform stuff to OpenGl. Please note that the
+ * the other MoTo matrices are row major.
+ *
+ * This class should be deprecated in favour of the more consistent
+ * MT_Matrix4x4. Please do not start using this class.
