Matthias Schiffer	0f6c467566	World: Chunk: replace division/modulo with shift/mask for height values ... Preparation for negative y coordinates.	2021-12-11 22:50:23 +01:00
Matthias Schiffer	457e993c92	Introduce separate types for block/section/chunk indices ... Newtypes are cumbersome in C++, so this is mostly documentation for now. Also replace lots of questionable uses of size_t with int or types with explicit width and add a few comments for constants.	2021-12-11 22:50:23 +01:00
