    Did you consider using images as I suggested.

Yes. I wanted to do it with faces ;-). It's worth doing with images also.

I still think Emacs should not slow down appreciably just because an
application uses lots of faces - unless you are doing something with those
faces (e.g. updating them) dynamically. I think there might be something to
look into there (after the release, if someone knowledgeable is interested).
But I know nothing about the display code; I'm just being stubbornly
optimistic.

    That must be quite trivial, and besides running faster (I
    assume)

Yes, I'm sure that using an image would be both easy and fast. Sometimes I
like hard and slow ;-).

    you get over problems with font selection that you have now.

Not a problem. The code works fine with any font - you just get a larger or
smaller palette. The problem was that I was assuming that everyone had a
particular font - now the font is an option.

I'm very ignorant wrt fonts. I was mainly pointing out my ignorance and the
poor shape of the Emacs doc about fonts.
