[svn-r4252] Purpose:

document update Description: The information of setting SGI_ABI seemed to confuse some user. Removed it since it is extra information in addition to the preferred method of "CC=... ./configure". Experienced user in IRIX64 would know that option. Platforms tested: Eyeballed.

    \qmlclass Animation QmlAbstractAnimation
  \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
        x: NumberAnimation {
            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.

    Unlike \c stop(), \c complete() immediately fast-forwards the animation to
    its end.  In the following example,

    Rectangle {
        x: NumberAnimation { from: 0; to: 100; duration: 500 }

    calling \c stop() at time 250ms will result in the \c x property having

    100, exactly as though the animation had played the whole way through.

    \qmlclass RotationAnimation QmlRotationAnimation
    \inherits PropertyAnimation
    \brief The RotationAnimation element allows you to animate rotations.

    RotationAnimation is a specialized PropertyAnimation that gives control
    over the direction of rotation.

    The RotationAnimation in the following example ensures that we always take
    the shortest rotation path when switching between our states.
    \qml
    states: {
        State { name: "180"; PropertyChanges { target: myItem; rotation: 180 } }
        State { name: "-180"; PropertyChanges { target: myItem; rotation: -180 } }
        State { name: "180"; PropertyChanges { target: myItem; rotation: 270 } }
    }
    transition: Transition {
        RotationAnimation { direction: RotationAnimation.Shortest }
    }
    \endqml

    By default, when used in a transition RotationAnimation will rotate all
    properties named "rotation" or "angle". You can override this by providing
    your own properties via \c properties or \c property.

    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: "InOutQuad" } }
    \endqml
    \o In a Behavior

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

    Repeatedly animate the rectangle's x property.
    \qml
    Rectangle {
        x: SequentialAnimation {
            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 Value Source / Behavior
    \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.

           y: Behavior { NumberAnimation {} } //animate theRect's y property
       }
       \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
       Rectangle {
           id: theRect
           width: 100; height: 100

               PropertyChanges { target: uselessItem; x: 10; y: 10; z: 2 }
           }
           transitions: Transition {
               //animate both theRect's and uselessItem's x and y to their final values
               NumberAnimation { properties: "x,y" }

               //animate theRect's z to its final value
               NumberAnimation { target: theRect; property: "z" }
           }
       }
       \endqml
    \row
    \o Standalone
    \o When an animation is used standalone, both the target and property need to be
       explicitly specified.
       \qml
       Rectangle {
           id: theRect
           width: 100; height: 100
           color: Qt.rgba(0,0,1)
           //need to explicitly specify target and property
           NumberAnimation { id: theAnim; target: theRect; property: "x" to: 500 }
           MouseArea {
               anchors.fill: parent

           }
