Inline elements generate boxes.

Possible, sure, but display:none is already part of the 'display'
property, so we have to handle it in the longhands *somehow*.  Plus,
this is very familiar to authors.  Third, display:contents is clearly
related to display:none, but not clearly related to visibility.
Finally, visibility is already well-established as just being a visual
effect - it still causes things to generate boxes, while display:none
does not, so 'visibility' isn't a great fit for the functionality.

We've used the term "layout mode" for a long time.  My blog post with
the sketch of this is 2 1/2 years old, and I've been complaining about
the issue for longer than that.  Finally, Bert wrote up the first
version of this ('display-model' and 'display-role') in Template
Layout even before I came into the group.

I don't understand.  The 'display' property explicitly handles all of
the legacy values appropriately.  There's nothing else to be
compatible with.
