Whoops! "My" approach would not work here. Clearly I need to study some
code. Luckily there is lots to be had. I'm still happy though that the Abi
layout code can place multiple containers on a page correctly. This alone
makes me happy. Now at least I know we can mostly reuse that code to place
containers where we we want.

No offense taken, it is true I know I am. I have found though that
sometimes it helps to not have pre-conceived ideas about what can be done.

Complex Maths doesn't scare me all:-) I know a lot about that.

Luckily it wasn't a Piece Table bug :-). Of those I've found none that I
didn't introduce working through Fields.
