v6: What is needed for release?

[xAndrewx]

    new GuiBitmapCtrl("iPhonePMWindowHead") {
      position = {32, 16};
      extent = {32, 32};
      
      bitmap = temp.head;
      drawimagerectangle(0, 0, temp.head, 0, 64, 32, 64);
    }

Displays the image as this: (btw temp.head = "head19.png")
