This call would internally duplicate #original_ld, override necessary configurations for shadow computations. It will return:
1) Generated shadow edges in format of LineartElementLinkNode which can be directly loaded into later main view camera occlusion stage. 2) Shadow render buffer if 3rd stage reprojection is need for silhouette/lit/shaded region selection. Otherwise the shadow render buffer is deleted before this function returns.
