wumpus-expr

Copperbox revision 2810.

More work on the interpreter, excepting function defs it now evaluates the expression datatype and produces a bounding box.

As the expression datatype has unrestrained effects there is a lot of potential for the interpreter to be wrong. I think an alternative direction might be to change the expression type so it is more operational like Andy Gill's Blank Canvas. This would make it easier to trust the interpreter. The potential downside is that this makes the embedded language less like PostScript / JavaScript.
