    Add polyhedron files for cubic globes.
    
    One for an orthogonally oriented cube, with the poles at the top and
    bottom face centres and the Greenwich meridian running down the centre
    line of one of the side faces; one for a cube oriented with the poles
    at cube vertices, and a cube edge running along the Greenwich meridian
    northwards from the south pole, leaving Greenwich itself near a face
    centre and bisected by the face diagonal that forms the northern part
    of the meridian.
    
    This commit just adds the polyhedron files themselves, and doesn't yet
    build nets out of them.

    Add -dNOSAFER to the gs command.
    
    Since I last ran this makefile, Ghostscript seems to have switched its
    default so that Postscript files it loads can't open other files. In
    this case, I need it to (and the primary source file is trusted,
    having been built just now by the same makefile).

    Fill the whole clipping path in the background colour.
    
    When projecting this globe on to a cube rather than an icosahedron,
    the polygons I used to cover the whole globe in sea-blue don't quite
    work; I think what must be happening is that some polygon that ought
    to overlap a cube face is being misprojected.
    
    Rather than invent a finer mesh, it's easier just to add a fill up
    front of the whole clip path in the handwritten part of the file.

    Actually generate PDFs of cubic globe nets.
    
    The only extra mechanism I've had to introduce here is a way to vary
    the drawnet.py options between the various nets being generated.
