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: 2016-2022 Blender Authors`

OpenGL immediate mode: interface_draw.c (cont) ui_draw_but_COLORBAND Introduced a new checker shader to be used mostly on transparent areas. OpenGL immediate mode: interface_draw.c (cont) ui_draw_but_UNITVEC Introduced a new shader to be used for simple lighting. 2017-02-07 13:04:08 +01:00
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: Fix static compilation errors - Missing explicit cast to `int` for bitwise operator. - UBO struct member macro colision. Rename fixes it. 2022-12-09 00:10:14 +01:00			`fragColor = simple_lighting_data.l_color;`
GPU: Use `f` suffix for float literals They are actually already some literals with the `f` suffix that are in our shader codebase and we never had problem in the past 5 years (or even 8 years). So I think it is safe to do and improves convergence of codestyles.
