Re: Problems with setting face attributes for specific frames

[Richard Stallman]

    AFAICT, I do not currently change a face attribute for a single frame, but
    it sounds like a reasonable thing to want to do. Is getting rid of that
    possibility really necessary to be able to handle "changes in background
    mode due to setting the background color"?

Yes I think so.

    I still don't understand what that problem is, BTW.

To explain this would be a lot more work, and would not affect
this discussion.

    In any case, as I say, I don't use that feature today. The more important
    problem you would create for me (by your other proposal) would be to get rid
    of the ability to change a face attribute globally (for all frames at once).
    What is the reason for that proposal? AFAICT, you gave no reason; you just
    said you are thinking of making that change.

The motive is to make a big simplification in the face code.
Right now it is quite hard to maintain that code, because there are
many old and new interfaces, and it is often hard to figure out
the right way to reconcile them.
