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.
