-     * Note: Test cases compare the outcome visually even if it's slower than a byte-wise compare.
-     *       This is necessary, because the Deflate implementation differs on the different target
-     *       platforms and thus the outcome, even if visually identical, differs. Thus only a visual
-     *       test method makes sense. In addition bytewise differences shouldn't be important, if the
-     *       visual outcome is identical and thus the qr code is identical/scannable.
