Except that there's no way of indicating that you want to scale any of the 
axes alone.  You specify a vector that scales all three axes, every time.  That
you didn't specify a valid scale for some axes is taken by the program to mean
that you probably meant one, but it should definitely warn you in case that
isn't the case.
