Not a problem. I always like to help.  (Unfortunatly my real work suffers when I
get preoccupied elsewhere...)

If you know the size of the pool box, then refer to uv_mapping in the docs to
see how it gets applied.  You should be able to work out the proportions and
mathematics from that.  I may do some more playing with it later when I get a
chance.

"3.5.7.1  Supported Objects"
This section shows how the texture gets sampled and applied to a box object.
