Piglins (including variants) have snout/head pixels that cannot be seen normally

The bug

Each piglin variant has a total of 48 pixels in the head, about and tusk areas which are completely obscured by other areas of geometry in the head. It is impossible to see any of these pixels from the outside, and they are responsible for a considerable amount of Z-fighting on the inside.

Deleting these pixels from the entities' textures will result in no outward visual differences, reduce Z-fighting from within, decrease the file sizes, and communicate more clearly to resource pack developers that these pixels are in fact not necessary to include in the texture.

How to fix

Fixed versions of all three texture files are attached to this ticket. Fixing this should be as easy as replacing vanilla's current entity/piglin/piglin.png, entity/piglin/piglin_brute.png and entity/piglin/zombified_piglin.png textures with these fixed textures.

As these assets are modified versions of Mojang's own game assets, intended as a fix to the game, Mojang have all the rights to use these as a fix. If required for some reason, I give Mojang full permission to use these.
