WHY spread it out?  Why have the scanner do something you may not want it to
do, or do it not optimally?  For 8 bit data, this is done...but you have to
set the setpoints...or you lose data that you may or may not have wanted.

I don't want my histograms compressed.  I don't understand why you would
either.  What I want is to set the setpoints, and then expand the data to
fill the histogram.  It can be done automatically, or manually.  This is
just such minutia!  It is something that is just a no brainer little feature
that you want (I'm not saying it's a bad feature...but what is up with
spending so much time on it?)...and I don't get what the big deal is with
it.  It's not like you can't do it in PS!

Because it's in the middle of the space.

I don't see how that's useful.  What is it useful for?  How is that going to
make your output any better?
