m_count

int ON_RTreeNode::m_count

The m_branch[] array contains m_count elements 0 <= m_count <= ON_RTree_MAX_NODE_COUNT m_count must be a signed int to insure signed compares work correctly

m_level

int ON_RTreeNode::m_level

m_level must be a signed int to insure signed compares work correctly

=0 at leaf nodes, > 0 at branch nodes
