- Rename linearRingIsOriented => linearRingsAreOriented The function checks all linear rings of a Polygon, so the plural "rings" is more appropriate - Rename linearRingsAreOriented => linearRingssAreOriented The double s is appropriate because the check is done for all Polygons of a MultiPolygon This commit restores the function names from OpenLayers v4, they were changed (wrongly IMHO) in #7820.
