   The path contains a quadratic or cubic.
   The path contains fewer than four points.
   The final point isn't equal to the first point.

 It's OK if the path has:
   Several colinear line segments composing a rectangle side.
   Single points on the rectangle side.

 The direction takes advantage of the corners found since opposite sides
 must travel in opposite directions.
