By default Aseprite will not try to match flipped versions of the tiles (as it requires more CPU), but when we create a tileset we can specify which flips can be matched automatically (new Tileset::matchFlags() property). These flags are just for the Auto mode, if we manually insert a flipped tile, that is always supported, even when the matchFlags() are not specified.
