My idea is that no scaling should be done in the middle of the
processing (ie inside the net or engine), as this is just overhead to
work around something that doesn't make sense on that level anyway. I
can't see how it's better forcing the engine to scale data
everywhere, instead of having the user interface API do it when it's
actually needed... The same job done in the right place.
