-    \qmlclass SmoothedFollow QDeclarativeSmoothedFollow
-    \since 4.7
-    \inherits NumberAnimation
-    \brief The SmoothedFollow element allows a property to smoothly track a value.
-
-    The SmoothedFollow animates a property's value to a set target value
-    using an ease in/out quad easing curve.  If the animation is restarted
-    with a different target value, the easing curves used to animate to the old
-    and the new target values are smoothly spliced together to avoid any obvious
-    visual glitches by maintaining the current velocity.
-
-    The property animation is configured by setting the velocity at which the
-    animation should occur, or the duration that the animation should take.
-    If both a velocity and a duration are specified, the one that results in
-    the quickest animation is chosen for each change in the target value.
-
-    For example, animating from 0 to 800 will take 4 seconds if a velocity
-    of 200 is set, will take 8 seconds with a duration of 8000 set, and will
-    take 4 seconds with both a velocity of 200 and a duration of 8000 set.
-    Animating from 0 to 20000 will take 10 seconds if a velocity of 200 is set,
-    will take 8 seconds with a duration of 8000 set, and will take 8 seconds
-    with both a velocity of 200 and a duration of 8000 set.
-
-    The follow example shows one rectangle tracking the position of another.
-\code
-import Qt 4.7
-
-Rectangle {
-    width: 800; height: 600; color: "blue"
-
-    Rectangle {
-        color: "green"
-        width: 60; height: 60;
-        SmoothedFollow on x { to: rect1.x - 5; velocity: 200 }
-        SmoothedFollow on y { to: rect1.y - 5; velocity: 200 }
-    }
-
-    Rectangle {
-        id: rect1
-        color: "red"
-        width: 50; height: 50;
-    }
-
-    focus: true
-    Keys.onRightPressed: rect1.x = rect1.x + 100
-    Keys.onLeftPressed: rect1.x = rect1.x - 100
-    Keys.onUpPressed: rect1.y = rect1.y - 100
-    Keys.onDownPressed: rect1.y = rect1.y + 100
-}
-\endcode
-
-    The default velocity of SmoothedFollow is 200 units/second.  Note that if the range of the
-    value being animated is small, then the velocity will need to be adjusted
-    appropriately.  For example, the opacity of an item ranges from 0 - 1.0.
-    To enable a smooth animation in this range the velocity will need to be
-    set to a value such as 0.5 units/second.  Animating from 0 to 1.0 with a velocity
-    of 0.5 will take 2000 ms to complete.

-    \code
-    Rectangle {
-        id: rect1
-        width: 20; height: 20
-        color: "#00ff00"
-        y: 200  // initial value
-        SequentialAnimation on y {
-            loops: Animation.Infinite
-            NumberAnimation {
-                to: 200
-                easing.type: Easing.OutBounce
-                easing.amplitude: 100
-                duration: 2000
-            }
-            PauseAnimation { duration: 1000 }
-        }
