wumpus-core

Copperbox revision 1712.

I've changed the printing order so it matches SVG and PostScript. The first element in a list of PrimElement is drawn first...

This has the unfortunate consequence that the Z-Order of drawing has now changed, but it makes most sense that the drawing order matches the two output formats. To handle Z-Order "comfortably", Wumpus-Basic should be extended with some notion of layers, although this won't be soon.
