The surface box property IS NOT the root box or anything. It has nothing to
do with the actual root box. It is just a special property that "bubbles up"
through the box hierarchy.

There isn't currently any way for a box to know when its surface changes.

What widgets need to know when they change their surface and why do they
need to know? (I think I've asked you this before... sorry if I missed you
reply.)
