Box intersection that cannot be represented?

[clarisma]

Since Box can represent a bounding box that straddles the Antimeridian, there may be a situation where such a Box is intersected with a regular bbox. Conceptually, such an intersection might result in two bboxes (the eastern and western parts). What happens at this point, since the resulting Box cannot represent more than one single bounding box?

• an empty Box is returned; or
• an exception is thrown (which one? A custom type?)
