-DESCRIPTION OF PROBLEM:
-=======================
-
-The 4-sided brush in the middle of the room (brush 0) has a duplicate plane.
-The last side (side 4) is a duplicate of the third side (side 2) with the
-vertexes re-arranged.
-
-I wanted to make sure that ChopWindingInPlaceAccu() is doing the right thing
-by setting a winding to NULL when all its points lie on the plane that the
-winding is being chopped with. This seems to be the case. My concern was
-that both windings for that duplicate plane will be NULL'ed out.
-
-Seems that some other code might be fixing duplicate planes. That's OK.
