I _must_ be getting old -- it would never occur to me to write something
as dense and incomprehensible (and no, removing the "dict([" would not
make it much clearer).  Something like:

pos2d = {}
for s, (x, y, delta) in positions.iteritems():
    pos2d[s] = x+dx*delta, y+dy*delta

seems just  SO much clearer and more transparent to me.
