title: Multiline Label with truncating
body: <p>In my app in Xamarin.Forms I have a label that I want to be multiline but only to a certain point. After that it must be truncated. How can I achieve this?</p>
  
  <p>Currently I can set the <code>LineBreakMode</code> to <code>WordWrap</code>; this creates a multiline label, but there is no truncating.</p>
  
  <p>If it changed the <code>LineBreakMode</code> to <code>TailTruncation</code>, it always truncates after one line.</p>
