Via some function that extracts a valid face from a window parameter.
Actually, the only interesting thing IMO is the background attribute.  I
don't think that changing any other attributes would make sense.  But
the same holds for the current patch as well: You simply fill up the
rest of the window with the background of the remapped default face.  Or
am I missing something?

I don't know how face remapping works so I can't tell.  I thought that
remapping does recompute the default face.
