This is a heuristical constant; similar code is in the autohinter
(function `af_latin_metrics_scale_dim'). I'm quite sure that there
are reasons for it (unfortunately, there's no comment which explains
the adjustment sufficiently) -- maybe it's necessary to `sharpen' the
constraints to apply this miniscule scaling.
Can you provide samples where this scaling is harmful? Or do you
observe a bad effect in general?
