By the way, the second example found in
"http://wiki.povray.org/content/Reference:Camera#User_defined_projection"
uses "rotate", but it has no effect...:

// Only direction functions specified
#declare Camera01 = camera {
    user_defined
    direction {
      function { x }
      function { y }
      function { 1 }
    }
    location  <0,0,-2>
    rotate    y*5
}

Where am I wrong?
