chore: make yuzu REUSE compliant [REUSE] is a specification that aims at making file copyright information consistent, so that it can be both human and machine readable. It basically requires that all files have a header containing copyright and licensing information. When this isn't possible, like when dealing with binary assets, generated files or embedded third-party dependencies, it is permitted to insert copyright information in the `.reuse/dep5` file. Oh, and it also requires that all the licenses used in the project are present in the `LICENSES` folder, that's why the diff is so huge. This can be done automatically with `reuse download --all`. The `reuse` tool also contains a handy subcommand that analyzes the project and tells whether or not the project is (still) compliant, `reuse lint`. Following REUSE has a few advantages over the current approach: - Copyright information is easy to access for users / downstream - Files like `dist/license.md` do not need to exist anymore, as `.reuse/dep5` is used instead - `reuse lint` makes it easy to ensure that copyright information of files like binary assets / images is always accurate and up to date To add copyright information of files that didn't have it I looked up who committed what and when, for each file. As yuzu contributors do not have to sign a CLA or similar I couldn't assume that copyright ownership was of the "yuzu Emulator Project", so I used the name and/or email of the commit author instead.

video_core/host_shaders: Add CMake integration for string shaders Add the necessary CMake code to copy the contents in a string source shader (GLSL or GLASM) to a header file then consumed by video_core files. This allows editting GLSL in its own files without having to maintain them in source files. For now, only OpenGL presentation shaders are moved, but we can add GLASM presentation shaders and static SPIR-V generation through glslangValidator in the future. 2020-08-24 00:28:15 +00:00			`set(SOURCE_FILE ${CMAKE_ARGV3})`

video_core: Fix instances where msbuild always regenerated host shaders When HEADER_GENERATOR was included in the DEPENDS section of custom commands, msbuild assumed this was always modified.
