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