GLSL: Make gl_Layer and gl_ViewportIndex always be outside blocks. There was some ambiguity/contradiction in this behavior, and Khronos decided glslang should always have these outside blocks, rather than have stage/vendor/target variations. 2017-09-13 19:22:50 +00:00			`layout (viewport_relative) out highp int gl_Layer;`
