Solas Shader

**Features added/changed:** ``` + Added screen space ambient occlusion and shadows. Both work on normal terrain, Distant Horizons and Voxy LODs. Screen space shadows also extend the regular shadows even without Voxy or DH. + Reworked planar clouds to look more like real life cirrus clouds + Improved lighting on the ender protoplanetary disk + Improved blending between different sky effects + Improved red aurorae. Now they are way more saturated + Made cloud shadows a bit softer ``` **Features fixed:** ``` + Fixed shader failing to load on versions of Iris below 1.19.2 + Fixed some compatibility errors on 1.12.2 + Fixed volumetric clouds clipping through Voxy LODS + Fixed water artifacts with Voxy + Fixed water disappearing at 2 chunks render distance + Fixed end flashes not working correctly with Voxy + Fixed exponential fog noise taking very weird shapes + Fixed several compilation errors when toggling different options ``` **Features removed:** ``` - 512 shadowmap resolution. It makes no sense, really ```

**Features added/changed:** ``` + Added low Earth orbit. Flying to Y=100000 (by default, controlled by the Karman Line slider) will slowly transform the atmosphere into a planet below the player + Added pixelated shadows option + Added Overworld atmosphere options. There will be more of them soon + Improved Ender Black Hole and Protoplanetary Disk + Improved subsurface scattering + Improved LPV fog and increased its contrast and intensity + Adjusted planar clouds lighting ``` **Features fixed:** ``` + Fixed shader failing to compile when setting it to Low profile + Fixed gbuffers_hand error on OptiFine + Fixed exponential fog failing to reach far LODs with Voxy and Distant Horizons + Fixed realtime shadows not working on OptiFine + Fixed crepuscular rays being barely visible ```

**Features added/changed:** ``` + Added full support for Voxy mod. In the next Solas update I'll probably add screen space shadows to Voxy and DH LODs. + Remade and greatly improved volumetric clouds for better, more realistic lighting and shapes. Many things are still subject to change, but I'm mostly happy with them. + Completely reworked the Aurora Borealis. It is now much more realistic, dynamic and beautiful. And it's just the beginning so stay tuned! + Added generated emission to handheld and dropped items + Added shooting stars based on @SpacEagle17's implementation + Improved planar clouds lighting and blending + Added support for Colorwheel mod + Added rotating noise to the accretion disk of the Ender Black hole + Added subtle warping to clouds closer to the Ender Black hole to make them look like they're being pulled in + Added options to toggle specular highlights and textured fire/lava. + Added new materials to integrated PBR ``` **Features fixed:** ``` + Fixed some options missing their translations + Fixed multiple compilation errors + Fixed shader not working with Distant Horizons + Fixed nether portals turning green + Fixed Ender Nebula not changing at all when the player travels large distances + Fixed moon phases being mirrorred horizontally ```
