title: Calculate needed size for a TLabel
body: <p>Ok, here's the problem. I have a label component in a panel. The label is aligned as alClient and has wordwrap enabled. The text can vary from one line to several lines. I would like to re-size the height of the the panel (and the label) to fit all the text.</p>
  
  <p>How do I get the necessary height of a label when I know the text and the width of the panel?</p>
