I just confirmed this behavior. true/true on geos 2.2 true/false on
geos 3.0.
Please file this at http://trac.osgeo.org/geos, it's real, and it's
not right.

But,
SELECT
ST_Contains(
GeomFromText('POLYGON((0 0,0 11,11 10,10 0,0 0))', -1),
GeomFromText('POLYGON((5 5,5 6,6 6,6 5,5 5))', -1) );
returns FALSE
I thought the above would also return TRUE.
Is this behavior of ST_Contains correct?
