779	A bug for combination of IBC and WP	chujoh		"There is a bug for combination of IBC and WP.
When IBC and WeihgtedPredB or WeihgtedPredP are set to 1, the results between encoder and decoder are not identical.
The following changes should be introduced.


{{{
In /source/Lib/CommonLib/InterPrediction.cpp,
void InterPrediction::motionCompensation( PredictionUnit &pu, PelUnitBuf &predBuf, const RefPicList &eRefPicList
  , const bool luma, const bool chroma
  , PelUnitBuf* predBufWOBIO /*= NULL*/
)

  if( eRefPicList != REF_PIC_LIST_X )
  {
    CHECK(predBufWOBIO != NULL, ""the case should not happen!"");
