Transform Block Misaligns clipped_by Object in Union
-----------------------------------------
Use of transform {} misaligns any clipped_by object inside a union. This 
produces incorrect CSG.

Some code:

// code
union{
  sphere{0,1
   clipped_by{
    plane{y,0}
   }
  }
  sphere{0,1
   scale<1,.5,1>
   clipped_by{
    plane{-y,0}
   }
  }
  pigment{rgb 1}
  transform{
   translate y
   rotate z*45
  }
}
// end code
