Doc: Try to explain better when and how the easing curve is applied

Another example is QEasingCurve::InOutElastic, which provides an
elastic effect on the values of the interpolated variant.
+ QVariantAnimation will use the QEasingCurve::valueForProgress() to
+ transform the "normalized progress" (currentTime / totalDuration)
+ of the animation into the effective progress actually
+ used by the animation. It is this effective progress that will be
+ the progress when interpolated() is called. Also, the steps in the
+ keyValues are referring to this effective progress.
+
The easing curve is used with the interpolator, the interpolated()
virtual function, the animation's duration, and iterationCount, to
control how the current value changes as the animation progresses.
