763 At first stage the distance decoder decodes 6-bit "posSlot" value with bit
765 "posSlot" values.

803       is used for all posSlot values.
805 If (posSlot < 4), the "dist" value is equal to posSlot value.
807 If (posSlot >= 4), the decoder uses "posSlot" value to calculate the value of
810   If (4 <= posSlot < kEndPosModelIndex), the decoder uses bit tree decoders.
