947 * This function is much simpler than the old one. This is because
948 * the old function optimized to send as few face identifiers as possible,
949 * at the expense of sending more coordinate location (coordinates were
950 * only 1 byte, faces 2 bytes, so this was a worthwhile savings). Since
951 * we need 2 bytes for coordinates and 2 bytes for faces, such a trade off
952 * maps no sense. Instead, we actually really only use 12 bits for coordinates,
953 * and use the other 4 bits for other informatiion. For full documentation
954 * of what we send, see the doc/Protocol file.
955 * I will describe internally what we do:
956 * the ns->lastmap shows how the map last looked when sent to the client.
957 * in the lastmap structure, there is a cells array, which is set to the
958 * maximum viewable size (As set in config.h).
959 * in the cells, there are faces and a count value.
960 * we use the count value to hold the darkness value. If -1, then this space
961 * is not viewable.
962 * we use faces[0] faces[1] faces[2] to hold what the three layers
963 * look like.
