1233 * of what we send, see the doc/Protocol file.
1234 * I will describe internally what we do:
1235 * the ns->lastmap shows how the map last looked when sent to the client.
1236 * in the lastmap structure, there is a cells array, which is set to the

1238 * in the cells, there are faces and a count value.
1239 * we use the count value to hold the darkness value. If -1, then this space
1240 * is not viewable.
