  * type:  defect => enhancement


Comment:

 pramsey: yes, I think it would be a cast, but the function should only
 "cast" if a set of preconditions hold: approximate equidistance from the
 center, arc length matching the default number of quadrant segments (for 3
 points, with default quadrant segments being 8, the arc should cover not
 more than 3/8 of the quadrant). See also #2428.

 Changing to "enhancement".
