> For tree traversals and edge cases we still sometimes invoke full haversin
> (with asin() call and everything). this is not necessary: we just need to
> compute the exact sort key needed for comparisons.
> While not a huge optimization, its obviously less work and keeps the overhead
> of the BKD traversal as low as possible. And it removes the slow asin call
> from any hot path (its already done for sorting too), with its large tables
> and so on.
