When using difference and cutaway_textures to section through an object I
did not get the behaviour I expected (wanted).  My observation is that
object_1 sets the default texture to be as object_1 when cutaway is used but
subsequent applications of a texture to a compound object containing it
override object_1's texture.  It this a bug or the intended behaviour.

In the following example I would have expected the sphere and wedge to be
red with a blue cylinder.  When rendered I get a red sphere with a blue
wedge and cylinder.

union{
        difference {
          sphere { 0, 1  texture { pigment { color Red  } } } // object_1
          box    { 0, 1   }
          cutaway_textures
        }

        cylinder{0,y,.5}
        texture { pigment { color Blue } }
}
