World

The world is probably going to be represented with a k-d tree with each volume tagged with the information relevant to the block, in line with the graphics' representation.

There was consideration of native support for microblocks, but there was no compelling reason for them to exist that we found. We also considered world representations with width in blocks larger than the capacity for an i64, but that line of thought was never fully pursued. We decided to use i64 block coordinates over i32 block coordinates, because there was no real compelling case in favor of either, and bigger is better.
