  29 ** Samples          Number of samples to calculate.
  30 ** ScaleLeft        Left volume multiplier.
  31 ** ScaleRight       Right volume multiplier (not used for mono sounds).
  32 ** StartPointLeft   Sample value from last session, for interpolation. Update!
  33 ** StartPointRight  Sample value from last session, for interpolation. Update!
  34 ** Src              Pointer to source samples.
  35 ** Dst              Pointer to pointer to destination buffer. Update!
  36 ** FirstOffsetI     The offset value of the first sample (when StartPoint*
  37 **                  should be used).
  38 ** Offset           The offset (fix-point). Update!
  39 ** Add              Add value (fix-point).
  40 ** StopAtZero       If true, abort at next zero-crossing.
