/**
* 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.
