  44         Event to be fired, when the activity ends.

  46         @param rEventQueue
  47         Queue to add end event to
  48
  49         @param nMinDuration
  50         Minimal duration of the activity (might actually be
  51         longer because of nMinNumberOfFrames). Note that this
  52         duration must always be the <em>simple</em> duration,
  53         i.e. without any repeat.
  54
  55         @param rRepeats
  56         Number of repeats. If this parameter is invalid,
  57         infinite repeat is assumed.
  58
  59         @param nAccelerationFraction
  60         Value between 0 and 1, denoting the fraction of the
  61         total simple duration, which the animation should
  62         accelerate.
  63
  64         @param nDecelerationFraction
  65         Value between 0 and 1, denoting the fraction of the
  66         total simple duration, which the animation should
  67         decelerate. Note that the ranges
  68         [0,nAccelerationFraction] and
  69         [nDecelerationFraction,1] must be non-overlapping!
  70
  71         @param bAutoReverse
  72         When true, at the end of the simple duration, the
  73         animation plays reversed to the start value. Note that
  74         nMinDuration still specifies the simple duration,
  75         i.e. when bAutoReverse is true, the implicit duration
  76         doubles.
