Mo' Bends

The first Mo' Bends for Minecraft 1.21.1, on Fabric and NeoForge. It animates what 2.0.0-alpha.2 does on 1.12.2: players, zombies (husks and drowned too), skeletons, zombie villagers, zombified piglins, creepers, villagers, witches, iron golems, spiders (cave spiders too), squids (glow squids too) and wolves, with their armour, held items, capes, elytras, sword and arrow trails, and the supporters' accessories. 1.12.2 stays on 2.0.0-alpha.2.

Added

• Armour from GeckoLib mods bends with the body, cut at the elbows and knees (GeckoLib 4.6 and up, optional).
• Mods can add their own animated mobs, render layers and animation operations through the addon API (see docs/addons.md).
• Resource packs and mods can animate any mob, those 1.12 never had too: a model definition names its entity by registry id ("entity": "minecraft:fox", or a list of ids), and its bones' parts by their path in the model ("part": "body/head"). Any model can be bent, a mod's too.
• The Mo' Bends menu opens from the mod list's Config button (NeoForge, and Mod Menu on Fabric), while you're in a world.
• NeoForge tells you when a newer version of Mo' Bends is out.

Not yet

• The items 1.12 didn't have (spyglass, goat horn, brush, crossbow, trident) keep whatever pose the player was in.
• Mo' Bends doesn't ship animations for the mobs added after 1.12: resource packs can add them.
