Description
Mutiplies a 3d point by a 4x4 matrix.
Returns the resultant 4d point in the same parameter as the input point (pt).
Note : although a 4d point, only x, y and z are used from
the input point.
Since multiplying a 3d point by a 4x4 results in a 4x1 vector,
the w of the output point is calculated.
