IIRC Gerd decided to use a single property `display' rather than several properties, for reasons of performance. I do not know or remember what was the particular performance issue(s), tho, That is true, but we COULD have another kind of `margin' display spec which works like `before-string'. It would be more logical. So I wonder why it was not done that way. Maybe there was a reason.
