I mean the following:
a way to know "if I apply face `foo' (and only face `foo') to a chunk
of text in the current buffer, what will it look like: will it be bold?
what will be its size? ..."
`face-attribute' doesn't work here because it fails to take into account
the effect of face-remapping-alist.

Indeed, that seems to work, thanks.

Indeed, that's an additional problem.

I'm all for it.
