# The angles are wierdly complicated because of the wrap-around.
# You can imagine some horrible cases, like a circular patch of
# "linear object" in which all angles are represented or a gentle "U"
# curve.
#
# For now, I'm going to use the following heuristic:
#
# Compute two different "angles". The angles of one go
# from 0 to 180 and the angles of the other go from -90 to 90.
# Take the variance of these from the mean and
# choose the representation with the lowest variance.
#
# An alternative would be to compute the variance at each possible
# dividing point. Another alternative would be to actually trace through
# the connected components - both overkill for such an inconsequential
# measurement I hope.
