+        Event to be fired, when the activity ends.
+
+        @param rEventQueue
+        Queue to add end event to
+
+        @param nMinDuration
+        Minimal duration of the activity (might actually be
+        longer because of nMinNumberOfFrames). Note that this
+        duration must always be the <em>simple</em> duration,
+        i.e. without any repeat.
+
+        @param rRepeats
+        Number of repeats. If this parameter is invalid,
+        infinite repeat is assumed.
+
+        @param nAccelerationFraction
+        Value between 0 and 1, denoting the fraction of the
+        total simple duration, which the animation should
+        accelerate.
+
+        @param nDecelerationFraction
+        Value between 0 and 1, denoting the fraction of the
+        total simple duration, which the animation should
+        decelerate. Note that the ranges
+        [0,nAccelerationFraction] and
+        [nDecelerationFraction,1] must be non-overlapping!
+
+        @param bAutoReverse
+        When true, at the end of the simple duration, the
+        animation plays reversed to the start value. Note that
+        nMinDuration still specifies the simple duration,
+        i.e. when bAutoReverse is true, the implicit duration
+        doubles.
