2	This are tests that explicitly use the OverlayNG code line and XML test ops ("intersectionsr" and "intersectionng" for example) but do not pass. The same tests do pass in JTS.

11	general/TestOverlayLL.xml	1	25	FIXED, see https://trac.osgeo.org/geos/ticket/1043
12	general/TestOverlayAAPrec.xml	17	62	Note, these are all output structure differences, because NG is still discarding lower dimensional resultants that are formed by collapses.
13	general/TestOverlayLAPrec.xml	3	16
14	robust/TestRobustOverlayFixed.xml	1	1
15	issue/issue-geos-350.xml			Note, these are like the AAPrec and LAPrec issues, in that collapsed resultants lower than the highest dimension are discarded. They should probably be retained or odd effects ensue. (Differences with visual results return empty, for example)
16	issue/issue-geos-358.xml			This difference is the result of some small corridors snapping away in NG result, but surviving in Old result. A looser comparison is probably called for.
17	issue/issue-geos-360.xml			This difference is the result of some small corridors snapping away in NG result, but surviving in Old result. A looser comparison is probably called for.
