Nope, the left column *is* the result of the bytecode interpreter.
that's exactly what your screenshot is showing...

Another note, the middle column uses the "rsb_delta" and "lsb_delta"
adjustement values returned by the auto-hinter; this produces *much* better
spacing that using the auto-hinted advance widths alone...

I'll add a toggle to switch this feature on/off to see the difference
later.

You can't at the moment. ftdiff is a rather new test program, it doesn't
have all the bells and whistles of ftview at the moment. These will come,
but feel free to hack the code if you want to...
