* GetStreamOutElements is a callback function on the shadertype, just like ModifyCompilationEnvironment * If GetStreamOutElements is specified, the FShaderResource includes that shader type in its ID as it can't be shared with any other shader type. * FShader is no longer a FRenderResource which solves some multiple initialization issues #codereview Marcus.Wassmer [CL 2430024 by Daniel Wright in Main branch]
