OK, I will wait as I have some (larger) changes in Cell. I remade aabb's
so that they will work even if you rotate 90° around z and so on.

But I get in trouble there is no easy way to separate scaling and
(rotation+shear), right? Setting 1s on the diagonal is clearly nonsense,
although that is what we (I) do now.

Will write soon.
