I don't understand what you mean by "independent of that".  I perceive
a big difference between
-adobe-courier-medium-r-normal--17-120-100-100-m-100-iso8859-1 and
-adobe-courier-medium-r-normal--34-240-100-100-m-200-iso8859-1.  If
the user has specified a 24pt font in .Xresources, we should respect
that.

We currently don't have a way to respect that spec on Xft AFAIK, but
it's one of the things I work on off and on.  I see no reason why we
shouldn't allow any of the various font specs on any platform,
although in cases of ambiguity we should prefer different defaults for
different platforms.
