There are a few utilities for showcasing fonts/font families from a file in a Window. Windows has something like this (I forget the name); and on Linux you have gnome-font-view and perhaps something in KDE as well.
However - those don't let you see various metrics/dimensional features of fonts: The Em square, ascender and descender lengths, x-height vs M-height etc. You also typically can't compare sizes and measures against some other font as the baseline, or even a 1x1 box of some unit (cm, in, etc.).
Is there some utility which offers this functionality? If not, perhaps even a full-fledged font editor, or non-font application, which offers this?
