    cogl-primitives: Copy across the texture coordinates if no texture
    
    Previously when using the cogl_rectangle_* family of functions with a
    pipeline that doesn't have a texture for a particular layer then
    validate_tex_coords_cb would bail out immediately leaving the texture
    coords for that layer uninitialised. This patch changes it so that it
    bails out after copying in the texture coordinates instead. This was
    causing problems for pipelines that were trying to completely generate
    the texture values in a CoglSnippet because they wouldn't get any
    texture coordinates.
