License headers: add SPDX licenses for '.glsl' files When GLSL sources were first included in Blender they were treated as data (like blend files) and had no license header. Since then GLSL has been used for more sophisticated features (EEVEE & real-time compositing) where it makes sense to include licensing information. Add SPDX copyright headers to .glsl files, matching headers used for C/C++, also include GLSL files in the license checking script. As leading C-comments are now stripped, added binary size of comments is no longer a concern. Ref !111247 2023-08-24 10:54:59 +10:00			`/* SPDX-FileCopyrightText: 2018-2022 Blender Authors`

UI: desaturate toolbar icons that the mouse is not over. This does not look great with light toolbar buttons as in the default, so consider this a work in progress. 2018-04-26 15:42:08 +02:00
GPU: Shader: Make info files generated This is the first step of moving the create infos back inside shader sources. All info files are now treated as source files. However, they are not considered in the include tree yet. This will come in another following PR. Each shader source file now generate a `.info` file containing only the create info declarations. This renames all info files so that they do not conflict with their previous versions that were copied (non-generated).

GPU: Shader: Change vector and matrix type to use blender convention This unify the C++ and GLSL codebase style. The GLSL types are still in the backend compatibility layers to support python shaders. However, the C++ shader compilation layer doesn't have them to enforce correct type usage. Note that this is going to break pretty much all PRs in flight that targets shader code.
