Bad calculations with geometries in the 180 meridian (anti-meridian)

[UnaiUribarri-TomTom]

Let us define a rectangle that centred on the 180 meridian, with the north-west corner at latitude 1, longitude 179 and the east-south corner at latitude -1, longitude -179.

Some geometry calculations over this rectangle are invalid:

• the centroid is in the 0 meridian instead of the 180 meridian
• the envelope generated instead of being the given rectangle it covers the rest of the world, with latitudes from -179 to 179 instead of from 179 to -179.

AFAIK JTS is not aware of projections and works in a Cartesian space so this is expected IMO.
