This adds back compatibility for CoglShaders that reference the cogl_tex_coord_in[] or cogl_tex_coord_out[] varyings. Unlike the previous way this was done this patch maintains the use of layer numbers for attributes and maintains forwards compatibility by letting shaders alternatively access the per-layer tex_coord varyings via cogl_tex_coord%i_in/out defines that index into the array.
