    Untangle: turn #define VERTEX_NUMBERS into a preference.
    
    This compile-time definition switches the game into showing a distinct
    non-negative integer for each vertex, instead of indistinguishable
    blobs.
    
    Its main use to me in the past has been when I'm trying to planarise
    'real' graphs, that is, graphs I got from outside the game and wanted
    a planar embedding of. Having made one in Untangle's UI I could then
    read off which vertex was which.
    
    That's an unusual use of the game, but _might_ be useful to someone
    else. Perhaps a more interesting use of this feature would be to
    direct someone else's play verbally - it would be much easier to tell
    them which vertex to click on that way!
