title: Text line height
body: <p>How can I specify a line height in a multi-line Text / Label?</p>
  
  <p>It already seems it's not supported in css:</p>
  
  <blockquote>
    <p>JavaFX CSS does not support comma-separated series of font family
    names in the -fx-font-family property. The optional line height
    parameter when specifying fonts is not supported. There is no
    equivalent for the font-variant property.</p>
  </blockquote>
  
  <p>Is there a reason for this?</p>
  
  <p>Is there an alternative to set this in code? Or kinda emulate the functionality? I want to control vertical rhythm within my app.</p>
