  Yes.

  I didn't talk about fonts, I was talking about *generic* scheme
which might be reusable for other (all) kinds of objects and
environments.

  That depends on object type.

  If you think it should be 3rd for fonts, then it must be that way.

  I'm usually trying to generalize a solution if its worth that IMHO,
and for OE, a rather large system, having best practices of general
solutions is worthy aim IMHO. Still, everything is at right time, so
if you think what I've written above is not relevant to current issue
at hand, let's skip it.

  The described as above font handling is +1 from me.
