OK, you want to change the header-line and mode-line-inactive faces so
that they no longer inherit from the mode-line face?

But they aren't the only basic faces that have this problem --
`tab-line' inherits from `variable-pitch', for instance.

No, I don't.  I was thinking of altering `face-remap-add-relative' so
that it resolves the faces that inherit instead of leaving it to
redisplay.
