DTP misses direction [-1,-1] [1](https://github.com/petercorke/robotics-toolbox-python/blob/master/roboticstoolbox/mobile/DistanceTransformPlanner.py) ``` directions = np.array( [ # dy dx [-1, -1], [0, -1], [1, -1], [-1, 0], [0, 0], [1, 0], [0, 1], [1, 1], ], dtype=int, ) ``` This generates paths that can't go diagonally right-down.
