public static int main (string[] args) {
// Prepare mask as pattern
Cairo.ImageSurface source = new Cairo.ImageSurface (Cairo.Format.A8, 32, 32);
Cairo.Context context_src = new Cairo.Context (source);
context_src.set_source_rgba (0, 0, 0, 0.5);
context_src.rectangle (4, 4, 18, 18);
context_src.fill ();
context_src.rectangle (10, 10, 18, 18);
context_src.fill ();

Cairo.Pattern pattern = new Cairo.Pattern.for_surface (source);
pattern.set_extend (Cairo.Extend.REPEAT);

// Paint using prepared mask
Cairo.ImageSurface destination = new Cairo.ImageSurface (Cairo.Format.RGB24, 64, 64);
Cairo.Context context_dest = new Cairo.Context (destination);
