I had also tried this:

      #declare ImageMapScale=<4/3,1,1> * 2; // use < 2 for repeats
      pigment {CustomHalftone(Picture, ImageMapScale,
        pigment{image_map {jpeg "masking.jpg"}
         turbulence 0
         translate <4/3,1,0>/ImageMapScale},
        0, 0, 0)}

/* Using the same image for this as the base image and slight (0.01)
turbulence (when scale has *2) can be rather interesting */
