Comment (by pramsey):

 Ug, well an improvement is nice. I fear the only real full-on solution is
 the one Komzpa put in the old PR: feeding in any pre-existing coordinates
 to the generation function so they can be re-used... so the HexagonGrid
 function would have to carry a bunch of prior state, and the Hexagon
 function would have to be able to make use of said state.
 And that would still leave cases where independently generated hexagons
 from the same tiling space didn't have perfectly matching vertex values.
