Fix floating point precision errors at large distances

[muzikbike]

It might be a good idea to fix certain issues related to precision loss at high distances to improve playability. Here's a list of ones affecting 1.15 and 1.16:

Terrain generation:

• Ore generation (dangerous - can cause crashes!)

• Minecart with Chest generation in abandoned mineshafts (https://bugs.mojang.com/browse/MC-167421)

Blocks and entities:

• Primed TNT spawning from being blown up by other explosions (https://bugs.mojang.com/browse/MC-167047)

• Enchantment table book (https://bugs.mojang.com/browse/MC-167044)

• Mob spawning (https://bugs.mojang.com/browse/MC-167103)

Particles:

• Campfire embers (https://bugs.mojang.com/browse/MC-167042)

• Lava embers and their associated sounds (https://bugs.mojang.com/browse/MC-167046)

• Particles from adding eyes of ender to end portal frames (https://bugs.mojang.com/browse/MC-161969)

• Water dripping from leaves during rain (https://bugs.mojang.com/browse/MC-167091)

• Redstone repeater particles (https://bugs.mojang.com/browse/MC-167971)

• Bone meal particles (fixed in 1.16, so probably not worth it)

• Nether biome particles (1.16+) (https://bugs.mojang.com/browse/MC-170872)

• Rain particles (broken in 1.16+ only) (https://bugs.mojang.com/browse/MC-171035)

• Smoke from lava during rain (broken in 1.16+ only) (https://bugs.mojang.com/browse/MC-171035)

Instability particles from suspended gravel and other such blocks may also be affected.

EDIT: this has been fixed.

there's pretty much no more precision errors left in vanilla 1.16 now.

don't think theres any point in fixing any of these anymore - the mod for 1.16.1 already provides a relatively bug-free experience at high distances (1.16.2 even more so when it comes, no more crash) and this mod serves more as a way of demonstrating old exaggerated effects
