DESCRIPTION
     This engine takes as input a three dimensional floating-point vector and
     a transformation matrix. The vector is assumed to be a row vector.

     The engine multiplies the vector by the matrix and returns the result in
     the output point. The output direction contains the result when the
     matrix multiplication assumes the vector is a direction, and therefore
     ignores the translation part of the matrix. The output normalDirection
     contains the normalized direction

INPUTS
     SoMFVec3f           vector
          Input row vector.

     SoMFMatrix          matrix
          Input transformation matrix.


OUTPUTS
     (SoMFVec3f)         point
          Vector transformed by matrix.

     (SoMFVec3f)         direction
          Vector transformed by matrix, ignoring translation.

     (SoMFVec3f)         normalDirection
          Normalized direction.
