Initialize uninitialized globals in GLSL output Initializing globals is done by the DeferGlobalInitializers AST transformation, which makes sure that the global variable init proceeds in the correct order. This is important since some global variables may use other uninitialized globals in their initializers. The global variable init is only done in case the WebGL shader spec is being followed. This avoids adding global initializers twice in case the same shader goes through multiple translations, assuming only one of them is a WebGL shader translation.
