tboxnode_quadtree_next() static void tboxnode_quadtree_next ( const TboxNode *  nodebox, const TBox *  centroid, uint8  quadrant, TboxNode *  next_nodebox  ) static Calculate the next traversal value. All centroids are bounded by TboxNode, but SP-GiST only keeps boxes. When we are traversing the tree, we must calculate TboxNode, using centroid and quadrant.
