Adding test case from issue #480

boost::geometry::intersection(bigTileOn90,usa,out1);
boost::geometry::intersection(bigTile,usa,out2);
BOOST_CHECK(out1.size() == 1);
BOOST_CHECK(boost::geometry::area(out1) == boost::geometry::area(out2));

Shouldn't we use a floating-point check with epsilon?

That should be OK without epsilon because the two computed polygons are exactly the same and thus their areas.


BOOST_AUTO_TEST_CASE(usaIntersectBigTile90) {
auto bigTileWKt = "POLYGON((-182.25 -2.25,-182.25 85,-90 85,4.5 85,4.5 -2.25,-90 -2.25,-182.25 -2.25))";
auto bigTileWKtOn90 = "POLYGON((-182.25 -2.25,-182.25 90,-90 90,4.5 90,4.5 -2.25,-90 -2.25,-182.25 -2.25))";

I think we never use this camelCase convention...
Also (minor), can be const

Thanks you are right, I was just copy-pasting here from the original issue. Fixed now.
