1019 | * maps no sense. Instead, we actually really only use 12 bits for coordinates, |
|
|
1020 | * and use the other 4 bits for other informatiion. For full documentation |
|
|
1021 | * of what we send, see the doc/Protocol file. |

1025 | * maximum viewable size (As set in config.h). |
|
|
1026 | * in the cells, there are faces and a count value. |
|
|
1027 | * we use the count value to hold the darkness value. If -1, then this space |
|
|
1028 | * is not viewable. |
|
