Round-off errors in metrics & fontinst/finst status...

I'm just curious as to whether whether anyone is working on fixing these
issues anytime in the near(ish) future. I've already written a Perl
script that is an `AFM rounder', but am considering some gross hacks to
either MTX files and/or fontinst itself to better support fractional
widths. I would gladly abandon such efforts if I knew that sometime soon
there would be a new version of fontinst that understood such things.
It'd also be useful to know just how much difference the current `round
to an integer' process makes -- Berthold Horn did seem pretty outraged
at the very idea, but are other people similarly upset by these
inaccuracies. Is there a noticable difference? Similarly, when vptovf
and pltotf squark about how they had to round things, I'm left wondering
if I should or shouldn't care... (and if I am supposed to care, just what
it is I'm supposed to do).
