Implementation
(Point2f center, double radius) minEnclosingCircle(VecPoint points) {
final center = calloc<cvg.CvPoint2f>();
final pRadius = calloc<ffi.Float>();
cvRun(() => cimgproc.cv_minEnclosingCircle(points.ref, center, pRadius, ffi.nullptr));
final rval = (Point2f.fromPointer(center), pRadius.value);
calloc.free(pRadius);
return rval;
