din: scale result
I'd like the output to fill the range -1..+1, but it's not doing that and I'm
uncertain on what exactly the scaling factor should be here.
In one reference a factor of 1/sqrt(.75) is specified, but in my tests that
doesn't seem to quite fill the range but it doesn't seem to blow it out so
it seems safe for now.
