title: Text in QML rendered different accross platforms
body: <p>I am seeing inconsistencies in the rendering of text between different platforms:</p>
  
  <p><a href="https://i.stack.imgur.com/kji1n.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/kji1n.png" alt="enter image description here"></a></p>
  
  <p>The image on the top left is produced in android, and as the red guide lines indicate, it differs from the "reference" windows output in terms of vertical position and angle of the italic style.</p>
  
  <pre><code>Rectangle {
    width: 100
    height: 50
    color: "grey"
    Text {
      x: 4
      y: 2
      font.family: sysfont
      font.pixelSize: 13
      width: contentWidth
      color: bgc
      text: "Type"
    }
    Text {
      x: 5
      y: 13
      font.family: sysfont
      font.pixelSize: 32
      font.italic: true
      font.letterSpacing: -1
      width: contentWidth
      color: topc
      style: Text.Sunken
      styleColor: bgc
      text: "Name"
    }
  }
  </code></pre>
  
  <p>Any ideas what causes that? It is the same font, the same code. Top padding and line height values are identical across the platforms. </p>
