- disable_boundary_filter flag was not reset within the TU loop. This
caused the flag to remain sticky at 1 for all subsequent TUs in the
CTB once set by any TU.
- Transform-skip blocks larger than 4x4, the scaling/dequantization
matrix is bypassed and the scaling factor is set to a constant of 16
as per HEVC specification section 8.6.3.
- Bypassing the inverse transform for transform-skip blocks requires
applying a scaling of tsShift (Rec. ITU-T H.265 Section 8.6.2
Eq 8-296: tsShift = 5 + log2_trans_size) and descaling of bdShift
(Eq 8-295: bdShift = 20 - bit_depth).
Net shift: shift_ts = bdShift - tsShift
(20 - bit_depth) - (5 + log2_trans_size)
15 - bit_depth - log2_trans_size.
