title: Indentation in WPF TextFormatter
body: <p>I'm making a WPF text-editor using TextFormatter. I need to indent some paragraphs, so I'm using the Indent property from the TextParagraphProperties class.</p>
  
  <p>This works great in this scenario:<br></p>
  
  <p>Regular text without any<br>
  indentation.<br>
  &nbsp;&nbsp;&nbsp;&nbsp;This paragraph has a uniform<br>
  &nbsp;&nbsp;&nbsp;&nbsp;indentation so everything is<br>
  &nbsp;&nbsp;&nbsp;&nbsp;ok.<br>
  <br>
  But I also need this:<br>
  &nbsp;&nbsp;&nbsp;&nbsp;John: This paragraph has a<br>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;diferent indentation<br>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;in the first line.<br>
  &nbsp;&nbsp;&nbsp;&nbsp;Joe:  So I don't know how<br>
  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;to make this happen.<br>
  <br>
  I found the ParagraphIndent and FirstLineInParagraph properties, but I don't know how they works, or if then would be usefull.</p>
  
  <p>Thanks in advance!!
  Jose</p>
