Increase size of WorldBoundaryShape to be much larger

The size was previously 20,000 pixels or units, which could be easily
reached in many projects. It is now 2,000,000,000,000,000 pixels or units,
which is larger than the supported coordinate space with a single-precision
build, and still very large in a double precision build.
