default geoCircle precision to 2 degrees

Open Fil opened this issue 2 years ago • 1 comments

Results in 180 control points instead of 60 (⨉3). The error is quadratic with the precision, with the worst case (for a parallel) being at latitude 45°. Under this new setting, the maximum error is now ~484m, vs. 4.365km with precision 6°.
