Some resource packs can break particle culling

[Lolothepro]

Minecraft Version: 1.21.1

NeoForge Version: 21.1.83

Steps to Reproduce:

1. Apply this resource pack: https://modrinth.com/resourcepack/3d-particles
2. Enable particle debugging and break a block, or wait for a slime to jump
3. The particles will have an offset

The particles are not aligned with the culling hitbox

The linked resource pack uses a core shader to generate the 3D geometry, ignoring particle scaling and, crucially, generates them at the wrong height (vanilla block break particles are perfectly centered in the hitbox, the 3D particles are centered at the top edge of the bounding box). The bounding box used for culling is already expanded a bit beyond the particle's collision bounding box, so I don't think there is anything we can realistically do about this.

Given that the resource pack implements its behavior by modifying the core shaders, which is explicitly unsupported by Mojang at the moment, we can't and won't do a lot about this issue.

At most, we could implement a config option to disable particle culling, so users of certain resource packs can disable it as necessary. Outside of that, I don't think we can do much to fix this outside of outright disabling particle culling permanently.
