Copperbox revision 2516.

I've remade the PosEvent type. Previously it had a rather exotic implementation because concatenating two PosEvents needed the orientation of the second before it could be computed (!). To avoid this I've added cheap displacement to the event answer type CatPrim. This means CatPrims can be moved after they have been computed, so PosEvent can directly support arrangements such as overlay or side-to-side.

Again, this is another improvement that would be good to back port to Wumpus.
