Muuf A.G.I Shaders

What's new Changelog:

[+] Added Screen Space Shadows for Distant Horizons chunks - SSS now extends beyond vanilla render distance and follows DH terrain with full resolution

[+] Added Rough Reflections with realistic material-based roughness

Fix:

[Fixed] Fixed Screen Space Shadows appearing completely black

[Fixed] Fixed terrain fog (Land Scattering) on both vanilla and Distant Horizons chunks - fog no longer appears overly thick at chunk edges on low render distances
