Instead of storing all block width, height and depths in their shifted form: block_width = 1U << block_shift; Store them like they are provided by the emulated hardware (their block_shift form). This way we can avoid doing the costly Common::AlignUp operation to align texture sizes and drop CPU integer divisions with bitwise logic (defined in Common::AlignBits).
