The very problem is that not all font formats have precomputed metric
values.  Another problem is how `ascent' and `descent' are defined.

Please tell us what you want to do with this data.  Then we can help
you better.

Do you really have a font with vertical kerning information?  It may
be possible that the code is buggy since we've never seen such a
thing...
