Description

Steps to reproduce:

DefaultGeographicBoundingBox box = new DefaultGeographicBoundingBox();
box.setBounds(-180, +180, -90, 90);
System.out.println(Extents.area(box));

The above computes zero with SIS 0.7. The reason is in the line that take in account boxes crossing the anti-meridian; the span reduction performed there is a little bit too much aggressive.
