I don't think we agreed on this. We agreed that that the 'surface' 
property should be a special property that bubbles up to the root box 
(or possibly some other box along the way in the case of some kind of 
MDI interface). The surface property isn't actually the root box. It is 
just a plain old object that contains some useful functions that the 
root box provides.

ibex.lib.surface contains a special object that has (or should have) 
some special functions that children use when the need to do something 
with the root box.

It isn't. Ever since the beginning XWT hasn't provided any way for a 
box to get a direct reference to one of its parents.
