    Description

      Today BytesRefArray uses one int (int[], overallocated) per
      value to hold the length, but for dimensional points these values are
      always the same length.

      This can save another 4 bytes of heap per indexed dimensional point,
      which is a big improvement (more points can fit in heap at once) for
      1D and 2D lat/lon points.
