I'm thinking of doing ref-counts and COW, so by default, if the new frame is
similar (e.g. on the same screen with the "same" frame parameters), so the
faces are inherited.  They can later get unshared if needed.

In typical usage patterns most frames are identical w.r.t faces and all
face-modification are applied uniformly to (almost) all frames.  So it should
be a valuable optimization.
