gl: Add some namespacing to the preamble symbols This adds a gsk prefix to the stuff in the preamble, as we want to avoid it conflicting with things in the main shader. Especially once we start allow some customization of shaders. 2020-09-18 09:35:29 +00:00			`vec4 diffuse = GskTexture(u_source, vUv);`
