This allows, for instance, cluster size summation for heatmaps to work when overzooming tiles that were generated with a retain points multiplier.

In addition, when tiles are generated with a multiplier and a feature order, the multiplier clusters are still sorted into that order, but the features within the cluster remain in spatial sequence instead, so that the default feature for each multiplier cluster remains the same feature that would have been included in the tile if there were no multiplier.
