1815 * This function uses the new map1 protocol command to send the map
1816 * to the client. It is necessary because the old map command supports
1817 * a maximum map size of 15x15.
1818 * This function is much simpler than the old one. This is because
1819 * the old function optimized to send as few face identifiers as possible,
1820 * at the expense of sending more coordinate location (coordinates were
1821 * only 1 byte, faces 2 bytes, so this was a worthwhile savings). Since
1822 * we need 2 bytes for coordinates and 2 bytes for faces, such a trade off
1823 * maps no sense. Instead, we actually really only use 12 bits for coordinates,
1824 * and use the other 4 bits for other informatiion. For full documentation
1825 * of what we send, see the doc/Protocol file.
1826 * I will describe internally what we do:
1827 * the socket->lastmap shows how the map last looked when sent to the client.
1828 * in the lastmap structure, there is a cells array, which is set to the
1829 * maximum viewable size (As set in config.h).
1830 * in the cells, there are faces and a count value.
1831 * we use the count value to hold the darkness value. If -1, then this space
1832 * is not viewable.
1833 * we use faces[0] faces[1] faces[2] to hold what the three layers
1834 * look like.
