Only with POINTS_MODE_PATHS.
AUTO_DIRECTIONS_FROM_FIRST_SEGMENT sets the direction (slope) of the ribbon from the direction of the first line segment. Recommended.
AUTO_DIRECTIONS_FROM_ALL_SEGMENTS in this mode the direction (slope) will be calculated for each line segment according to the direction vector between each point of the line segments. Slow method.
AUTO_DIRECTIONS_ENHANCED in this mode the direction (slope) will be calculated for each line segment according to the direction vector between each point of the line segments using a more sophisitcaed algorithm. Slowest method.
AUTO_DIRECTIONS_NONE you have to set the direction (slope) manually. Recommended.
