Clear volumetric fog texture on creation, this seems to could've caused problems even back on Alyx but issue is bigger now that we don't write to all volumetric fog froxels at once
Fix ClearUnorderedAccessViewUint not clearing properly for Texture2DArray and Texture3D
Specify .net 9 for shaders.yml
Fix sampletexture_bicubic (is anything using it)?
Compiled shaders with correct specular brdf
Specify setup-dotnet version for shaders.yml
Fog TAA + Tiled Rendering
* Fixes artifacts
* Improves perfomance
* Removes Clipmaps
* Lights are culled with tiles
* Makes fog render until far-z
* Removes ghosting
* Simplifies codebase a lot
Fix vignietting on DoF
DoF Blur size is in pixels, make it relative to screen resolution so size is consistent, do uv offset a bit after first sample so there's less shimmer
Fix messed specular on skin shader that was using old normalization curve

Add Motion.hlsl for motion vectors
Add generic TAA filter to Motion.hlsl
Remove overriding SkyIndirectLighting to false in hammer maps, a lot of public maps are built without lighting and rely on IBL to have ambient lighting, we don't have a good way to tell if a map has baked lighting on MapLoader, better to just keep this on and let artist elect if they want IBL lighting by themselves
Add experimental r_tiled_rendering_conservative_culling so people can play with it, uses near-z approach for tiled culling for even better perfomance, doesn't play well with translucents, will be deprecated when we have two sets of light lists
Don't do OnDisabled(); OnEnabled() on Skybox2D dirty but clean up probe cleanly if needed
Test tl, tr, bl and br corners instead of updownleftright for cone frustum culling
Tiled Frustum Culling (#1669)
SkyBox2D Indirect Lighting ( Reflections/IBL ) can be toggled, hammer maps don't expect skyboxes to be used for lighting since it has vrad
Apply cubemap normalization properly on flat ambient light
Apply subsurface scattering to IBL lighting, looks shit otherwise

VolumetricFogRenderer has it's own lightbinner outside of lightbinner pool, does lightbinning to fetch fog lights for the fog context only, fixes fog light settings not doing anything, deprecate LAYERFLAGS_NEEDS_FOG_CONTRIBUTING_LIGHTS since we don't need special code for that anymore
Don't update shadows on fog pass, some lights are set to be updated always but should all be fetched from cache
If Graphics.RenderTarget is not overriden, let it return the actual output rendertarget so you can fetch MSAA textures without copy ( you're going to shoot your own balls using this if you dont know what you're doing )
Fix Depth::GetLinear and add Depth::Linearize
Just get rid of F_DISABLE_Z_PREPASS entirely, it's not applicable for users to set it, static overlay uses BoolAttribute( NoZPrepass, true ); directly
use default depth_only combo for skin
Remove F_DISABLE_Z_PREPASS from shaders except if you want it explicit, remove it from eyeao until we recompile shaders
Enable autoexposure for other tonemaps
https://files.facepunch.com/sam/1b1311b1/sbox-dev_mAXJ3CQmYe.mp4
We were multiplying BRDF twice making envmaps look awfully dark
https://files.facepunch.com/sam/1b1311b1/E8pK9UTpn4.png
Avoid directional lights clipping with world with a reasonable value
Ensure proper number of maximum simultanious updates for EnvMapProbe dirty updates
Destroy buffers properly when deleting lightbinner
Move s_LightList out of singleton to the CLightObjectDesc, make other light-like object descriptors use CUtlVectorFixedGrowable instead of linked list ( trashes the cache while iterating ), all of them should be consistent now, use a single light descriptor for all light types
Tiled Culling Renderer buffers shouldn't live in Lightbinner, but instead on CLightCullingRenderer itself since they're rendered per view, so we just reuse that memory, Lightbinners are allocated in a pool, so all that memory was wasted on GPU, remove wasteful copy of binned lights on tiled light callback
Don't generate shadow frusta for unshadowed lights
Separate shadow generation, both shadow maps and the viewproj we pass, into SetupShadowsForLight in Lightbinner, when we do bindless shadows and lightbinner caching, this is where to look for it
Go back to do a copy of current light list for CLightCullVisibilityReadback, callbacks can have latency longer than one frame and that list could change
Cleanup, fix mixed logic for shadows
Fix lights and their cookies not being able to rotate on roll
Add stub GBuffer.hlsl for DepthNormals() mode and move ToolVis to it's own file and class so it's not a mess, aiming to remove ToolVis() mode, S_DISABLE_SPECULAR_HIGHLIGHTS not referenced anywhere
Don't add more lights to visible list than the list can permit, this relatively low limit is silly but don't want to break api until frustum tiled cull is here https://files.facepunch.com/sam/1b1011b1/parsecd_CiKjzyScdq.mp4
Revert "Fog Fix (#1661)", causing some slowdown problems, will be
brought back shortly
This reverts commit f0981cbaf9679a34c219f57cd232a638f60d463f.
Update compiled shaders with relative cubemap luminance
Fog Fix (#1661)
* Some lightbinner cleanup, allow it to be used directly without the complex system that scenesystem wants
* VolumetricFogRenderer has it's own lightbinner outside of lightbinner pool, does lightbinning to fetch fog lights for the fog context only, fixes fog light settings not doing anything, deprecate LAYERFLAGS_NEEDS_FOG_CONTRIBUTING_LIGHTS since we don't need special code for that anymore
* Share dynamic shadow atlas if we have more than one lightbinner per view ( for example, fog ), fix volume fog no shadows option, cleanup unused shit
* Put fog mode in it's own category and add nice icons to them
https://files.facepunch.com/sam/1b0611b1/zwd8qAJFu7.png
* These convars don't do anything or are redundant, some notes for tiled rendering in the future
* Remove deprecated VR stuff for volumetric fog on rendering pipeline, note for Alex that we can just reproject the frame for eye 2 for cheap volumetric fog rendering, any crumbs will be stripped more when I remove clipmaps
* One lightbinner per volumetric fog rather than creating it every frame
* Start removing fog clipmap rendering, there are better ways to do this and it's massive
* Disable clipmaps on managed code, clean up shader code
* Remove VR-specific frustum stuff from volumetric fog
* Get rid of redundant data
* Separate two passes cleanly, remove accumulation TAA, we'll do a proper big pants one
* TAA stub
* Fancy volumetric fog taa, move what was on integration step to previous pass, so this has pretty much the same cost and memory footprint as previously but much higher quality
* Proper fog TAA with ping-ponging accumulation textures
* Iterate fog denoising
* Do soft TAA jitter and encode non-final texture to a softer color space so that TAA bbox is also softer
* Final cleanup, fix fog density, fix obsolete error
Fix perfomance validation warning on depth_only shader, it never produces output from PS, any operations from ps for translucents are clip or discard, D_WRITE_DEPTH_MASKS is never used
Strip D_WRITE_DEPTH_MASKS from the rest
Fix shadows not showing up on non-scenecamera views like Hammer
Allow for multi-bounce reflections on EnvmapProbe
Make sure all cubemaps are up to date when loading/unloading mapinstances, cubemaps placed on scene weren't getting updated
GPU Shadow Culling light list is stored on camera where it should belong rather than on lightbinner, a lightbinner can be shared across multiple views causing issues, this also guarantees proper lifetime of list since lightbinner pool is only flushed on shutdown
https://files.facepunch.com/sam/1b0411b1/sbox-dev_Esvot2kDTb.mp4
Disable volumetric fog clipmaps by default, they're fucked right now with massive frame drops and they feel overengineered
Internal AfterDepthPrepass hooks
CSM doesn't suck anymore
Texel snap cascade shadow map matrix so lights never shimmer when you're moving
Cleanup
Use the frustum from the previous shadow map to cull the current shadow map, m_pLightObject neverr used
Pass rotation to cubemapper so rotated envmap probes captures are rotated the correct way
Fix Cubemap Brightness Normalization, uses prefiltered envmap instead of spherical harmonics, fixes overbrightened envmaps in dark areas, and increases overall contrast of envmaps
Update transform for skybox envmap
Correct curve for static_overlay custom fog blending for fog HDR values above 1.0f
https://files.facepunch.com/sam/1b1611b1/pl0WF6eu5Q.png
Move albedo chart to bottom right corner, make it scale more aggresively to not take away screen space
Add button to toggle albedo chart

Compile shaders with SSR fixes
SampleLevel so the two shaders that use lighting.fxc on VS can read it proper, let's also start getting rid of these texture macros
Complex Reflections as Devshader
Fix truncation warning on shadingmodel.hlsl
Fix complex_reflections, remove any dependencies to valve code
Use inline reflections for complex
Composite SSR always, might create some artifacts but will be dealt with
Detangle reflections api and document it
Adjustments, fix normals on complex reflections
Better document lightbinner and add a few asserts
Version tiled rendering if we ever make breaking changes to it's structure, makes sure that rendering doesn't break if we upgrade it in the future
Fix black cubemap fog on hammer
Cubemap Fog can be tinted, takes tint from main skybox as well https://files.facepunch.com/sam/1b3111b1/XWpxvX189A.png
sky.shader: g_flBrightnessExposureBias and g_flRenderOnlyExposureBias makes no sense when there's tint, barely any existing skyboxes used it properly
Update SkyBox2D component to apply tint to IBL environment probe
https://files.facepunch.com/sam/1b3111b1/G0298YogbO.png
Terrain_Normal: dY was inverted
Reenable terrain specular and recompile it with normal fixes
Terrain_Normal calculates world space normals properly now, remove sobel filter to just a simple bilinear
