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.

Merge of first part of changes from the apricot branch, especially the features that are needed to run the game. Compile tested with scons, make, but not cmake, that seems to have an issue not related to these changes. The changes include: * GLSL support in the viewport and game engine, enable in the game menu in textured draw mode. * Synced and merged part of the duplicated blender and gameengine/ gameplayer drawing code. * Further refactoring of game engine drawing code, especially mesh storage changed a lot. * Optimizations in game engine armatures to avoid recomputations. * A python function to get the framerate estimate in game. * An option take object color into account in materials. * An option to restrict shadow casters to a lamp's layers. * Increase from 10 to 18 texture slots for materials, lamps, word. An extra texture slot shows up once the last slot is used. * Memory limit for undo, not enabled by default yet because it needs the .B.blend to be changed. * Multiple undo for image painting. * An offset for dupligroups, so not all objects in a group have to be at the origin.

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.

GPU: add gpu python module with export_shader() function to export GLSL shader. shader = gpu.export_shader(scene,material) Returns the GLSL shader that blender generates to produce the visual effect of material in scene for the purpose of reusing the shader in an external engine. This function is meant to be used in a material exporter so that the GLSL shader can be exported entirely. The return value is a dictionary containing the shader source code and all associated data. The full documentation is under sphinx. Warning: there has been an API between the patch and this commit: uniform['lamp'] and uniform['image'] now return python reference to ID block instead of ID name as before. The X3D exporter that uses this function must be adapted.

Eevee: GPU Material node graph optimization. Certain material node graphs can be very expensive to run. This feature aims to produce secondary GPUPass shaders within a GPUMaterial which provide optimal runtime performance. Such optimizations include baking constant data into the shader source directly, allowing the compiler to propogate constants and perform aggressive optimization upfront. As optimizations can result in reduction of shader editor and animation interactivity, optimized pass generation and compilation is deferred until all outstanding compilations have completed. Optimization is also delayed util a material has remained unmodified for a set period of time, to reduce excessive compilation. The original variant of the material shader is kept to maintain interactivity. Also adding a new concept to gpu::Shader allowing assignment of a parent shader from which a shader can pull PSO descriptors and any required metadata for asynchronous shader cache warming. This enables fully asynchronous shader optimization, without runtime hitching, while also reducing runtime hitching for standard materials, by using PSO descriptors from default materials, ahead of rendering. Further shader graph optimizations are likely also possible with this architecture. Certain scenes, such as Wanderer benefit significantly. Viewport performance for this scene is 2-3x faster on Apple-silicon based GPUs. Authored by Apple: Michael Parkin-White Ref T96261 Pull Request #104536

GPUShader *GPU_pass_shader_get(GPUPass *pass);
Fix crash when editing shaders on Intel HD 4000. In the Intel HD 4000 driver a shader has to be deleted in the same context in which it is created. However, because you can't use a rendering context on different threads, to maintain the multithreaded compilation, the solution was to use the `GL_ARB_get_program_binary` and copy the binary generated for the shader and generate a shader on the main context using that binary. This solution is limited only to Intel HD 4000 and windows. Reviewers: fclem Reviewed By: fclem Differential Revision: https://developer.blender.org/D5019

GPUMaterial: Add Material shader cache. This is mostly to avoid re-compilation when using undo/redo operators. This also has the benefit to reuse the same GPUShader for multiple materials using the same nodetree configuration. The cache stores GPUPasses that already contains the shader code and a hash to test for matches. We use refcounts to know when a GPUPass is not used anymore. I had to move the GPUInput list from GPUPass to GPUMaterial because it's containing references to the material nodetree and cannot be reused. A garbage collection is hardcoded to run every 60 seconds to free every unused GPUPass.
