surface ++= ?

Any ideas on how we're going to make surface traps work?

ie
<ibex>
  <ui:box>
    surface ++= function(v) { ... }
  </ui:box>
</ibex>

That should be triggered whenever a box changes surface (which will
almost always happen at least once when a box is slotted into it's
initial surface).

Can this be done in the widgets or is this a core issue?

I'm frankly not satisfied with the SizeChange ++= (or possibly
width/height ++=) hack that we currently have to use.
