New b-intra mode where direction is contextual Preliminary patch on a new 4x4 intra mode B_CONTEXT_PRED where the dominant direction from the context is used to encode. Various decoder changes are needed to support decoding of B_CONTEXT_PRED in conjunction with hybrid transforms since the scan order and tokenization depends on the actual direction of prediction obtained from the context. Currently the traditional directional modes are used in conjunction with the B_CONTEXT_PRED, which also seems to provide the best results. The gains are small - in the 0.1% range.
