 * This test applies the OP's code to his example PDF file and indeed, there is an offset!
 * This is due to the <code>LegacyPDFStreamEngine</code> method <code>showGlyph</code>
 * which manipulates the text rendering matrix to make the lower left corner of the
 * crop box the origin. In the current version of this test, that offset is corrected,
 * see below.
