-    \class GfxEasing
-    \ingroup group_animation
-    \brief The GfxEasing class provides easing curves for controlling animation.
-
-    Easing curves describe a function that controls how a value changes over
-    time.  Easing curves allow transitions from one value to another to appear
-    more natural than a simple linear motion would allow.  The GfxEasing class
-    is usually used in conjunction with the GfxTimeLine class, but can be used
-    on its own.
-
-    To calculate the value at a given time, the easing curve function requires
-    the starting value, the final value and the total time to change from the
-    starting to the final value.  When using the GfxEasing class with
-    GfxTimeLine, these values are supplied by the GfxTimeLine.  When using
-    the GfxEasing class on its own, the programmer must specify them using
-    the GfxEasing::setFrom(), GfxEasing::setTo() and GfxEasing::setLength()
-    methods, or by passing them explicitly to the GfxEasing::valueAt() method.
-
-    For example,
-    \code
-    GfxEasing easing(GfxEasing::InOutQuad);
-    easing.setFrom(0);
-    easing.setTo(1000);
-    easing.setLength(1000);
-
-    for(int milliseconds = 0; milliseconds < 1000; ++milliseconds)
-        qWarning() << "Value at" << milliseconds << "milliseconds is
-                   << easing.valueAt(milliseconds);
-    \endcode
-    will print the value at each millisecond for an InOutQuad transition from
-    0 to 1000 over 1 second.
-
-    When using a GfxTimeLine, the values are communicated implicitly.
-    \code
-    GfxTimeLine timeline;
-    GfxValue value(0);
-
-    timeline.move(value, 1000, GfxEasing(GfxEasing::InOutQuad), 1000);
-    \endcode
-    In this case, any values set using the previous setter methods would be
-    ignored.
