Assuming you mean the centering one, it was real, but it can be addressed 
much more easily using the mechanism I gave (center the group, then offset 
the group by half the bounding box).

So extend it, and implement "nearestViewportElement". XBL gives you the 
tools to do this -- you could even simply write a binding that applied to 
all elements that implemented this property.
