     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.
