    \qmlclass Animation QDeclarativeAbstractAnimation
    \since 4.7
    \brief The Animation element is the base of all QML animations.

    The Animation element cannot be used directly in a QML file.  It exists
    to provide a set of common properties and methods, available across all the
    other animation types that inherit from it.  Attempting to use the Animation
    element directly will result in an error.

/*!
    \qmlproperty bool Animation::running
    This property holds whether the animation is currently running.

    The \c running property can be set to declaratively control whether or not
    an animation is running.  The following example will animate a rectangle
    whenever the \l MouseArea is pressed.

    \code
    Rectangle {
        width: 100; height: 100
        NumberAnimation on x {
            running: myMouse.pressed
            from: 0; to: 100
        }
        MouseArea { id: myMouse }
    }
    \endcode

    Likewise, the \c running property can be read to determine if the animation
    is running.  In the following example the text element will indicate whether
    or not the animation is running.

    \code
    NumberAnimation { id: myAnimation }
    Text { text: myAnimation.running ? "Animation is running" : "Animation is not running" }
    \endcode

    Animations can also be started and stopped imperatively from JavaScript
    using the \c start() and \c stop() methods.

    By default, animations are not running. Though, when the animations are assigned to properties,
    as property value sources, they are set to running by default.

    If the animation is not running, calling this method has no effect.  The
    \c running property will be false following a call to \c complete().

    Unlike \c stop(), \c complete() immediately fast-forwards the animation to
    its end.  In the following example,
    \code
    Rectangle {
        NumberAnimation on x { from: 0; to: 100; duration: 500 }
    }
    \endcode
    calling \c stop() at time 250ms will result in the \c x property having
    a value of 50, while calling \c complete() will set the \c x property to
    100, exactly as though the animation had played the whole way through.

    \brief The PropertyAnimation element allows you to animate property changes.

    PropertyAnimation provides a way to animate changes to a property's value. It can
    be used in many different situations:
    \list
    \o In a Transition

    Animate any objects that have changed their x or y properties in the target state using
    an InOutQuad easing curve:
    \qml
    Transition { PropertyAnimation { properties: "x,y"; easing.type: "InOutQuad" } }
    \endqml
    \o In a Behavior

    Animate all changes to a rectangle's x property.
    \qml
    Rectangle {
        Behavior on x { PropertyAnimation {} }
    }
    \endqml
    \o As a property value source

    Repeatedly animate the rectangle's x property.
    \qml
    Rectangle {
        SequentialAnimation on x {
            repeat: true
            PropertyAnimation { to: 50 }
            PropertyAnimation { to: 0 }
        }
    }
    \endqml
    \o In a signal handler

    Fade out \c theObject when clicked:
    \qml
    MouseArea {
        anchors.fill: theObject
        onClicked: PropertyAnimation { target: theObject; property: "opacity"; to: 0 }
    }
    \endqml
    \o Standalone

    Animate \c theObject's size property over 200ms, from its current size to 20-by-20:
    \qml
    PropertyAnimation { target: theObject; property: "size"; to: "20x20"; duration: 200 }
    \endqml
    \endlist

    Depending on how the animation is used, the set of properties normally used will be
    different. For more information see the individual property documentation, as well
    as the \l{QML Animation} introduction.

    These properties are used as a set to determine which properties should be animated.
    The singular and plural forms are functionally identical, e.g.
    \qml
    NumberAnimation { target: theItem; property: "x"; to: 500 }
    \endqml
    has the same meaning as
    \qml
    NumberAnimation { targets: theItem; properties: "x"; to: 500 }
    \endqml
    The singular forms are slightly optimized, so if you do have only a single target/property
    to animate you should try to use them.

    In many cases these properties do not need to be explicitly specified -- they can be
    inferred from the animation framework.
    \table 80%
    \row

    \o When an animation is used as a value source or in a Behavior, the default target and property
       name to be animated can both be inferred.

       \endqml
    \row
    \o Transition
    \o When used in a transition, a property animation is assumed to match \e all targets
       but \e no properties. In practice, that means you need to specify at least the properties
       in order for the animation to do anything.
       \qml
