Combination of within and difference return wrong result

The following program returns `false` while it should return `true`.

```cpp
#include

int main() {
using NT = double;
using Point = boost::geometry::model::d2::point_xy;
using Polygon = boost::geometry::model::polygon;
using MultiPolygon = boost::geometry::model::multi_polygon;

Polygon star_elem_horizontal; //blue
Polygon star_elem_vertical; //yellow
Polygon star_1; //red
Polygon star_2; //green

boost::geometry::read_wkt("POLYGON((25 0,0 15,30 15,22 10,25 0))", star_elem_horizontal);
boost::geometry::read_wkt("POLYGON((5 0,15 25,25 0,15 5,5 0))", star_elem_vertical);
boost::geometry::read_wkt("POLYGON((5 0,7 10,0 15,10 15,15 25,20 15,30 15,22 10,25 0,15 5,5 0))",
star_1);
boost::geometry::read_wkt("POLYGON((15 0,17 10,10 15,20 15,25 25,30 15,40 15,32 10,35 0,25 5,15 0))",
star_2);

MultiPolygon mp1;
boost::geometry::difference(star_elem_horizontal, star_elem_vertical, mp1);

MultiPolygon mp2;
boost::geometry::difference(mp1, star_2, mp2);

MultiPolygon mp3;
boost::geometry::difference(star_1, star_2, mp3);

std::cout << boost::geometry::within(mp2, mp3) << std::endl;

return 0;
}
```

It seems like a numerical precision issue. If we use `boost::multiprecision::number >` as `NT` then we get the desired output i.e. true.
