Comment(by strk):
UPDATE: boundary intersections are now included in the result, and GEOS
can be built to automatically use RectangleIntersection from the standard
intersection API by defining USE_RECTANGLE_INTERSECTION macro at compile-
time.
Doing that enables a lot of other tests existing for general intersection.
Some of them fail for the removal of boundary vertexes which are already
covered by an edge segment, as reported by Mika on the mailing list. That
we want fixed.
Some of them fail due to the presence of duplicated vertices, minor but
also worth fixing.
Some are failing badly, returning invalid multipolygons.
A good starting point is ./tests/general/TestFunctionAA.xml
I'll keep looking at them.
