No, it is another function like vrotate, vaxis_rotate, vnormalize, etc.
It simply allows you to do full transforms on a vector instead of just
rotation.
vrotate(vectA, rotationAmt)
is the same as
vtransform(vectA, rotate rotationAmt)
I will attempt to upload a .zip which contains more of my patch work(and
all of the current WyzPov stuff, although with syntax changes) to
povray.binaries.programming.
