title: acroform text field not align to right
body: <p>I have <a href="https://drive.google.com/uc?id=1jFbsYGFOnx8EMiHgDsE8LQtfwJHSa5Gh&amp;export=download" rel="nofollow noreferrer">this acro form</a></p>
  
  <p>I am trying this code to align field to right : </p>
  
  <pre><code>acroForm.getField("NewRentWithoutChargesChf").setValue("1.00");
  ((PDTextField) acroForm.getField("NewRentWithoutChargesChf")).setQ(PDVariableText.QUADDING_RIGHT); //align right not works
  </code></pre>
  
  <p>I expect field to be right aligned but it doesn't (still left).</p>
