* Thor says: Keep hands off this Layer_Info. There's really nothing in
* here to play with. The only thing you possibly may be interested in
* is the top_layer that points to the topmost layer of this layer_info,
* and the Lock which locks this structure. Even that is quite private,
* but everything else is really really private. Leave all this to
* layers.library as some fields are likely to change their meaning
* in the near future.
