We could default face-no-inherit to t and set it to nil when we realize
a face and follow a :inherit.  I.e. all automatic.

Or we could call it `children' instead of `face-no-inherit', default it to
nil, and add faces to it whenever we find them while realizing faces, then
we could flush only the children rather than all_faces.
