Tile Matrix object. Documents the structure of the tile matrix at each zoom level in each tiles table. It allows GeoPackages to contain rectangular as well as square tiles (e.g. for better representation of polar regions). It allows tile pyramids with zoom levels that differ in resolution by factors of 2, irregular intervals, or regular intervals other than factors of 2.
