Sorry, I was going to follow up to this earlier, but
got side tracked.

I just posted some more earlier today on CLT:

its a brief outline of what I had to do.

Actually, for now, I would be happy to take the bbox
method, to identify coords of the item in question
(per column too). If this was there, then the code I
worked up would be half the size most likely. Of
course I would rather have a full solution :) but
having the bbox would go a long way.
