Block model cuboids and their textures are misaligned compared to vanilla

[WeegeeTheDoggo]

Bug Description

Expected: Block models and textures to line up as they normally do in vanilla

Actual: Block models and textures are slightly out of line

I believe this to be a bug. It does not happen with any other mods, or just by using Fabric itself, or in vanilla. I'm not aware of a setting that could remedy this, after looking through all the in-game settings for Sodium and testing each one. This bug affects an unknown number of block models, but I can verify it in end rods, torches, and fences. I expect that it affects many more.

Normal:

Using Sodium:

Reproduction Steps

• Make sure fabric-loader-0.14.21-1.20.1 is installed
• Download fabric-api-0.86.0+1.20.1 and sodium-fabric-mc1.20-0.4.10+build.27 and place them into the mods folder
• Launch Minecraft Launcher
• Select fabric-loader-0.14.21-1.20.1 profile
• Wait for game to load, then enter a world and look closely at block model (such as end rod) (use spectator mode if needed)

I can reproduce this on my system.

Vanilla has its own alignment issues with models as well. (#1316)

I wonder if it'd be possible for Sodium to fix this issue and the vanilla cases as well (#1607). There exist mods such as Model Gap Fix and Model Fix Multi which resolve vanilla's issues with this, so integrating such a fix into Sodium as well so that more people can benefit would be a nice touch.

We can't really fix any of these vertex precision issues until the fluid renderer is rewritten to not abuse them. At that point, it should become possible to correct the off-by-one issue which affects texture coordinates, since it won't cause texture gaps in fluid rendering.

The issue described here should be fixed with ea01727.
