- count the per-chunk density of specific blocks
- count the per-chunk density of dungeons, by measuring the number of zombie/skeleton/regularspider spawners
- count the per-chunk-per-biome density of trees, by measuring the number of dirt-log vertical transitions, correlating to biome data
- draw a vertical map of the world based on a specific measured value (biome, elevation, ...)
This project is Windows-only, although it shouldn't be too difficult to make it portable.

/** The base class for all chunk-processor callbacks, declares the interface.
The processor calls each virtual function in the order they are declared here with the specified args.
If the function returns true, the processor moves on to next chunk and starts calling the callbacks again from start with
the new chunk data.
If the function returns true, the processor doesn't process the data item, moves on to the next chunk
and starts calling the callbacks again from start with the new chunk data.
So if a statistics collector doesn't need data decompression at all, it can stop the processor from doing so early-enough
and still get meaningful data.
A callback is guaranteed to run in a single thread and always the same thread.
A callback is guaranteed to run in a single thread and always the same thread for the same chunk.
A callback is guaranteed to run on all chunks in a region and one region is guaranteed to be handled by only callback.
