piexel a648ef6622 Build object meshes from a block grid instead of a BlockVector map
Every face looked up its neighbour in a HashMap keyed by BlockVector,
whose hash codes collide heavily; on the woodland mansion that took 1.8 s
of a 2.4 s build, so making a block see-through lagged by seconds. The
blocks now go into an array over the object's bounds, which brings the
build down to about 50-70 ms with the same faces. Opening an object gets
the same speed-up.
