The above images are examples of path classes introduced for the mixed, single-angle tests. Each path here starts in the upper left corner. Each class is defined by the position of the turn relative to the start point and the general angle of the turn. Different members of a class are generated by horizontally, vertically, and diagonally flipping configurations.
