    // GLSL 4.6 keywords, from https://github.com/KhronosGroup/OpenGL-Registry/blob/d00e11dc1a1ffba581d633f21f70202051248d5c/specs/gl/GLSLangSpec.4.60.html#L2004-L2322

    //
    // Note: The GLSL ES 3.2 keywords are the same as GLSL 4.6 keywords with some residing in the reserved section.
    // The only exception are the missing Vulkan keywords which I think is an oversight (see https://github.com/KhronosGroup/OpenGL-Registry/issues/585).
