Why does the following code generate a:
Warning: Unnecessary bounding object removed.
for each tile in the road?  (POV-Ray 3.5 beta 6)

Thanks,
Hershel

Code:

#declare TileSize = 8;
#declare I = -30;
#declare Road =
union {
   #while (I<=400)
      #declare J = -50;
      #while (J<=50)
         plane { y, -20
            bounded_by { box { <J,-30,I>, <J+TileSize,0,I+TileSize> } }
            clipped_by { bounded_by }
         }
         plane { y, -20
            bounded_by { box { <J+TileSize,-30,I+TileSize>,
<J+TileSize*2,0,I+TileSize*2> } }
            clipped_by { bounded_by }
         }
         #declare J=J+TileSize*2;
      #end
      #declare I=I+TileSize*2;
   #end
   texture {
      pigment {
         granite
         scale <0.3, 1, 0.3>
         colour_map {
            [0 1 colour Black
                 colour red 0.5 green 0.5 blue 0.5]
         }
      }
      finish {
         specular 1
         roughness 0.02
         reflection 0.25
      }
   } // texture
   no_shadow
}
