 For two-dimensional coordinate bounds, in the second step of the process, for each index pair `(j, i)` of the interpolated dimension, the four bounds of the boundary variable is set to the value of the interpolated bounds point grid at index pairs `B0`, `B1`, `B2` and `B3`, respectively, where the index pairs are defined above under <<compressing_two_dimensional>>.
