The OrderBy overload that takes an int generating key selector is faster than the one that requires a custom comparer. We extract a function from the ScreenZPosition function that determines the Z position of a WPos with an offset, but does not account for the tileset height. For the ordering function this is fine as only the relative magnitude of the comparison keys matter, so we don't need to spend time adjusting for the tileset height, as that won't affect the sort.
