post filter flip image up and down

[knupel]

the post filter shader reverse image, the reason is maybe there twice call of the same shader and the layer of the first is reverse ?
that's happen here warp_image_graphic_processor()

if(shader_warp_filter) { 
      try {
        // rope_warp_shader.set("flip_source",true,false);
        result.filter(rope_warp_shader);
      } catch(java.lang.RuntimeException e) { 
        printErrTempo(60,"class Warp void warp_image_graphic_processor: Too many calls to pushMatrix()",frameCount);
      }
    }
