Yes, maybe that is the best way, I am not sure.

I did not mean giving the zero height ot width. That would be
confusing. I meant visibility as a new property.

That sounds very good. To throw away that part of my code in winsav.el
I would need three more things:

- Rotate
- Transpose

- Resizing.

Actually the reszing code when putting back a window tree in winsav
was one of the most frustrating pieces of code I have written because
it had to fight what the C code was doing. I think the resizing code
is one of those pieces that should be written in C. It should be much
more simple there (the logic I mean ...).
