Comment (by darkblueb):
Testing dataset **Valids-Delft** for valid-invalid policy evaluation,
under construction [https://trac.osgeo.org/geos/wiki/Valids-Delft here]
Currently all Valids-Delft tests use counter-clockwise winding for outer-
shell, and clockwise winding for inner-shell(s). Permutations of winding
are planned.
**DrJTS** says: JTS will continue to be insensitive to windings at this
time (sep19).
