[css-containment] ED of Containment ready for review (was overflow:clip)

The ED for the 'contain' property is now ready for review and possible
WD publication: <http://dev.w3.org/csswg/css-containment/>.

This is the property that originated as my suggestion for "overflow:
clip", for stronger layout isolation.  As discussed on this list, it
grew a bit to encompass more than just overflowing, so that using the
property actually isolates the element's subtree *completely*

Please review and let me know if I missed anything, or if there's
anything that's not sane there.

If you have good suggestions for how to split the containment up into
a few pieces, and good justification for why you'd want this
(preferably pointing to something real-world that could benefit from
being isolated but needs to violate some of the assumptions of strict
containment), we can make the property alternately accept a few
feature keywords that turn on isolation per-feature.

I'm aiming for a WD request in the next week or so, so review soon is
appreciated!
