I didn't explicitly mention it in my reply to the previous version,
but we would want to use the same naming scheme here and for other
helpers as well. (So wined3d_vec3_normalise(),
wined3d_color_mul_add(), wined3d_vec3_m3x3(), etc.)

Here too, it seems like init_transformed_lights() could reuse most of
wined3d_ffp_get_vs_settings().
