    Kluge around problems with picking nodes in HyperViewer on Windows. · 56dc5eb9

    I will have to fix the bug in PyOpenGL argument passing to get
    picking working right.
    
    Meanwhile, I put in a simple work-around hack: when you pick a graph
    edge in the spanning tree displayed by HyperViewer, the node it leads
    to is picked instead.  (The edge has a negative integer ID, while the
    node it leads to is positive.)
    
    This also gives the ability to "zip" along edges of the graph, which
    I kind of like.  It's not a very good substitute for picking nodes,
    but might be worth keeping even after node picking works.  We can
    also define our own semantics for picking edges in the graph...
