title: QLabel add 'border' around text
body: <p>Is it possible to add a slight 'border' atop and below the text displayed in a <code>QLabel</code>? The border should not be at the edge of the <code>QLabel</code>. Instead it should have a padding of something like 10px to the displayed text. The size of the border would be 75% of the <code>QLabel</code> width, starting at 12.5%. Also if the text changes, the 'border' should stay the same:</p>

  <p>Furthermore it should still be possible to set the background color of the <code>QLabel</code> via a <code>QStylesheet</code> or some other API. </p>
