render/gles2: move shaders to individual files Instead of having a C file with strings for each shader, move each shader into its own file. Use a small POSIX shell script to convert the files into C strings (can't wait for C23 #embed...). The benefits from this are: - Improved readability and syntax highlighting. - Line numbers in shader compiler errors are easier to make sense of. - Consistency with the Vulkan renderer. - Shaders will become more complicated as we add color management features. 2022-10-26 12:03:50 +02:00			`embed = find_program('./embed.sh', native: true)`
