True.  Chris also pointed this out to me.  But its useful if we want to
extend the scaling notion to work with non-reals (eg. 8-bit or 16-bit
integers) as they do in netCDF.  So why not leave it in?

Yes.  But that'll get complicated and annoying with many different
variables each having different depth profiles, right?

If the scaling isn't easy to do (say, there is no mean thats easy to
remove) then we can always fall-back to the per-field use of Real*8's.
