(From update of attachment 14236)
I don't think you need to add  the boxLayer() method.  The cost of layer() is
completely negligible if you get the O(n^2) stuff out of the way.

I know it looks like it mattered because I added that hasLayer() stuff
recently, but it was really only showing up because it was being called a
ludicrous number of times (and even then it was only like 1%).
