 <p>The padding is likely part of the font, not the widget. Fonts need space above and below the space for average sized characters to make room for <a href="http://en.wikipedia.org/wiki/Ascender_%28typography%29" rel="nofollow">ascenders</a> and <a href="http://en.wikipedia.org/wiki/Descenders" rel="nofollow">descenders</a>. The larger the font, the more space that is needed . Without the space below, for example, where would the bottom part of a lowercase "g" or "y" go?</p>
