This function tries to get the closest projected segments along two end points. The x,y of s1, s2 are aligned in frame-buffer coordinates, only z,w are different. We will get the closest z/w as well as the corresponding global coordinates.

            (far side)
l-------r [s1]  ^
      _-r [s2]  |    In this situation it will essentially return the coordinates of s2.
   _-`          |
l-`             |
 
                   (far side)
            _-r [s2]   ^
         _-`           |   In this case the return coordinates would be `s2l` and `s1r`,
l-----_c`-----r [s1]   |   and `r_new` will be assigned coordinates of `c`.
   _-`                 |
l-`                    |

Returns true when a new cut (c) is needed in the middle, otherwise returns false, and *r_new_xxx are not touched.

Does the 3rd stage reprojection, will not re-load objects because #shadow_ld is not deleted. Only re-projects view camera edges and check visibility in light camera, then we can determine whether an edge landed on a lit or shaded area.

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.
