And in any case, the scaling only affects the faces that are used to
display buffer text.  Other parts of the Emacs display, like display
margins and the mode line, aren't affected.  So the same face will
behave as scaled when it is on buffer text, and as unscaled elsewhere.
That's why we needed text-scale-remap-header-line-face in the first
place, right?  This is a subtlety that needs to be kept in mind, if
not made more widely known, when we are expecting that more and more
faces scale together with the default face.
