// LightingThread.h
// Interfaces to the cLightingThread class representing the thread that processes requests for lighting
// Note that the world generators need direct access to the lighting methods so that they can light the generated chunk
/*
Lighting is done on whole chunks. For each chunk to be lighted, the whole 3x3 chunk area around it is read,
then it is processed, so that the middle chunk area has valid lighting, and the lighting is copied into the ChunkMap.
Lighting is calculated in full char arrays instead of nibbles, so that accessing the arrays is fast.
Lighting is calculated in a flood-fill fashion:
1. Generate seeds from where the light spreads (full skylight / light-emitting blocks)
2. For each seed:
- Spread the light 1 block in each of the 6 cardinal directions, if the blocktype allows
- If the recipient block has had lower lighting value than that being spread, make it a new seed
3. Repeat step 2, until there are no more seeds
The seeds need two fast operations:
- Check if a block at [x, y, z] is already a seed
- Get the next seed in the row
For that reason it is stored in two arrays, one stores a bool saying a seed is in that position,
the other is an array of seed coords, encoded as a single int.
Step 2 needs two separate storages for old seeds and new seeds, so there are two actual storages for that purpose,
their content is swapped after each full step-2-cycle.
The thread has two queues of chunks that are to be lighted.
The first queue, m_Queue, is the only one that is publicly visible, chunks get queued there by external requests.
The second one, m_PostponedQueue, is for chunks that have been taken out of m_Queue and didn't have neighbors ready.
Chunks from m_PostponedQueue are moved back into m_Queue when their neighbors get valid, using the ChunkReady callback.

The object takes requests for generating chunks and processes them in a separate thread one by one.
The requests are not added to the queue if there is already a request with the same coords
Before generating, the thread checks if the chunk hasn't been already generated.
It is theoretically possible to have multiple generator threads by having multiple instances of this object,
but then it MAY happen that the chunk is generated twice.
If the generator queue is overloaded, the generator skips chunks with no clients in them
Generating works by composing several algorithms:
Biome, TerrainHeight, TerrainComposition, Ores, Structures and SmallFoliage
Each algorithm may be chosen from a pool of available algorithms in the same class and combined with others,
based on user's preferences in the world.ini.
See http://forum.mc-server.org/showthread.php?tid=409 for details.
