    Fix parent/children tile traversal · 2483c2d8

    * When input tile zoom is in maxzoom we only care about traversing parents until root
    * When input tile zoom is between 0 and maxzoom we traverse both parents (up to the root) and children up to maxzoom
    * When input tile zoom is 0 we traverse only children up to maxzoom
    * If a tile is already discovered stop recursion
