Digital BW, The Print

Or, to make things simple to program...
Two 256pixel wide windows: Top window shows 8 bit histogram, as you move
mouse over this, or perhaps click on a cursor-key, or whatever, the bottom
histogram could show you the 256 level wide detail of a particular 'hi-8-bit
value'.

Does that make sense?

Not quite a zooming / panning / all singing histo, but should be relatively
simple and quick to implement and run. At least... for those programs that
even bother to allocate a whole 256 pixels of screen real-estate to what
they must perceive as a boring histogram ;)
