Comment (by mdavis):

 Replying to [comment:5 strk]:
 > I thought SetPrecision was made, in GEOS-3.9, to retain validity ?

 Yes, SetPrecision preserves the validity of valid inputs. But it does not
 change invalid inputs into valid ones (which is what is being asked here).
 That requires completely different logic, which is in MakeValid.
