Great; but it'd be best if you ran this by Calum first, to see how it
meshes with the keynav in the rest of GNOME.

Sure.

Yes, is seems reasonable to use a heuristic based on (but not identical
with) the current font size.  However in such a case you may want to
clamp the font size to the theme's size for large values (for instance,
values greater than 20 points), since otherwise gucharmap could get too
big (presumably the user has chosen an 'application font' size that s/he
can see reasonably well).

For instance:

guchar_cell_font_size = MAX ( MIN (app_font_size * 1.5, 20.0),      
                              app_font_size);
