Re: [Feature request] face property `raise'

[Richard Stallman]

     A. Don't define different groups of different properties: make all
        properties text properties (or group all special = non-user-defined
        text properties together)

     B. Just provide one abstraction mechanism for all special properties
        with the ability to merge the abstract properties (like face
        merging).

That is an interesting idea.  Could you try writing a precise
spec for what it would look like?

One complication will be how to extend face customization to handle an
unbounded set of properties.  Right now there is a fixed set of face
attributes.
