License Headers: Set copyright to "Blender Authors", add AUTHORS Listing the "Blender Foundation" as copyright holder implied the Blender Foundation holds copyright to files which may include work from many developers. While keeping copyright on headers makes sense for isolated libraries, Blender's own code may be refactored or moved between files in a way that makes the per file copyright holders less meaningful. Copyright references to the "Blender Foundation" have been replaced with "Blender Authors", with the exception of `./extern/` since these this contains libraries which are more isolated, any changed to license headers there can be handled on a case-by-case basis. Some directories in `./intern/` have also been excluded: - `./intern/cycles/` it's own `AUTHORS` file is planned. - `./intern/opensubdiv/`. An "AUTHORS" file has been added, using the chromium projects authors file as a template. Design task: #110784 Ref !110783.

Cleanup: Add a copyright notice to files and use SPDX format A lot of files were missing copyright field in the header and the Blender Foundation contributed to them in a sense of bug fixing and general maintenance. This change makes it explicit that those files are at least partially copyrighted by the Blender Foundation. Note that this does not make it so the Blender Foundation is the only holder of the copyright in those files, and developers who do not have a signed contract with the foundation still hold the copyright as well. Another aspect of this change is using SPDX format for the header. We already used it for the license specification, and now we state it for the copyright as well, following the FAQ: https://reuse.software/faq/

GPU: add mechanism for splitting up big gpu_shader_material.glsl file Compiling this big file for every Eevee material is bad for performance, and now that we are adding more nodes it gets worse. This patch adds a simple mechanism to split up that file, and use only the parts used by shader nodes. When a function is used by GPU_link, we detect which GLSL file it came from and use it in GLSL code generation automatically. Dependencies between GLSL files are manually specified, and function names must be unique across all GLSL files. Most of the actual splitting up will be done in later commits.

GPU: Make nodetree GLSL Codegen render engine agnostic This commit removes all EEVEE specific code from the `gpu_shader_material*.glsl` files. It defines a clear interface to evaluate the closure nodes leaving more flexibility to the render engine. Some of the long standing workaround are fixed: - bump mapping support is no longer duplicating a lot of node and is instead compiled into a function call. - bump rewiring to Normal socket is no longer needed as we now use a global `g_data.N` for that. Closure sampling with upstread weight eval is now supported if the engine needs it. This also makes all the material GLSL sources use `GPUSource` for better debugging experience. The `GPUFunction` parsing now happens in `GPUSource` creation. The whole `GPUCodegen` now uses the `ShaderCreateInfo` and is object type agnostic. Is has also been rewritten in C++. This patch changes a view behavior for EEVEE: - Mix shader node factor imput is now clamped. - Tangent Vector displacement behavior is now matching cycles. - The chosen BSDF used for SSR might change. - Hair shading may have very small changes on very large hairs when using hair polygon stripes. - ShaderToRGB node will remove any SSR and SSS form a shader. - SSS radius input now is no longer a scaling factor but defines an average radius. The SSS kernel "shape" (radii) are still defined by the socket default values. Appart from the listed changes no other regressions are expected.

Cycles: merge of cycles-x branch, a major update to the renderer This includes much improved GPU rendering performance, viewport interactivity, new shadow catcher, revamped sampling settings, subsurface scattering anisotropy, new GPU volume sampling, improved PMJ sampling pattern, and more. Some features have also been removed or changed, breaking backwards compatibility. Including the removal of the OpenCL backend, for which alternatives are under development. Release notes and code docs: https://wiki.blender.org/wiki/Reference/Release_Notes/3.0/Cycles https://wiki.blender.org/wiki/Source/Render/Cycles Credits: * Sergey Sharybin * Brecht Van Lommel * Patrick Mours (OptiX backend) * Christophe Hery (subsurface scattering anisotropy) * William Leeson (PMJ sampling pattern) * Alaska (various fixes and tweaks) * Thomas Dinges (various fixes) For the full commit history, see the cycles-x branch. This squashes together all the changes since intermediate changes would often fail building or tests. Ref T87839, T87837, T87836 Fixes T90734, T89353, T80267, T80267, T77185, T69800

GPU: Split gpu_shader_material into multiple files. This patch continue the efforts to split the `gpu_shader_material` file started in D5569. Dependency resolution is now recursive. Each shading node gets its own file. Additionally, some utility files are added to be shared between files, like `math_util`, `color_util`, and `hash`. Some files are always included because they may be used in the execution function, like `world_normals`. Some glsl functions appeared to be unused, so they were removed, like `output_node`, `bits_to_01`, and `exp_blender`. Other functions have been renamed to be more general and get used as utils, like `texco_norm` which became `vector_normalize`. A lot of the opengl tests fails, but those same tests also fail in master, so this is probably unrelated to this patch. Reviewers: brecht Differential Revision: https://developer.blender.org/D5616
