Integration of 3D-HEVC merge related coding tools:
Inter-view motion merge candidate
 HHI_INTER_VIEW_MOTION_PRED
SAIT_IMPROV_MOTION_PRED_M24829, improved inter-view motion vector prediction
 QC_MRG_CANS_B0048 , JCT3V-B0048, B0086, B0069
OL_DISMV_POS_B0069 , different pos for disparity MV candidate, B0069
 MTK_INTERVIEW_MERGE_A0049 , second part
QC_AMVP_MRG_UNIFY_IVCAN_C0051
TEXTURE MERGING CANDIDATE , JCT3V-C0137

Notes: Two configurations are added:
PredDepthMapGen : 1
MultiviewMvPred : 7
