No, the normalize methods ensure that the column vectors are orthogonal
to each other. It does not alter the scale. (Earlier versions
of Java 3D had a bug that would force the scale to 1.0, but that was
never the intent). The main use of these methods is to correct for
floating point errors that accumulate over time when concatenating
a large number of rotation matrices.
