Take into account the plane rotation and flipping when calculating src positions for the wide plane parts. This is not an issue yet, because rotation is only supported for the UBWC planes and wide UBWC planes are rejected anyway because in parallel multirect case only the half of the usual width is supported for tiled formats. However it's better to fix this now rather than stumbling upon it later.
