+ @param nMinDuration
+ Minimal duration of the activity (might actually be

+
+ @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.
