Shadered Compat Fix

1.21.1 (NeoForge), 1.0.1:

Shader support (Iris)

• Shadered now works with Iris shader packs (tested with Complementary Reimagined). Blocks, skyblocks and models show on top of the shader pack instead of turning white or invisible.
• Shadered blocks are hidden behind your held item and anything else in front of them.
• Skyboxes inside Shadered blocks are drawn fresh every frame, so no more flicker or lag behind the camera.
• Shadered blocks and 3D models (cats, Maxwell…) now follow view bobbing with shaders on instead of sliding up and down while you walk.
• Shadered blocks no longer leave stray copies in the shader pack’s shadows.
• Better performance with a shader pack on.

Everything works exactly as before without a shader pack.
