title: Painting a custom JScrollBar
body: <p>I want to completely change the look of a scollbar but overriding <code>JScrollBar</code> and the <code>paintComponent</code> method doesn't work, the track and thumb are painted but the left and right arrows stay the same.<br>
  I am also using them inside a JScrollPane and using<br>
  <code>setHorizontalScrollBar( new CustomScrollBar() )</code> to set the scroll bars to my custom scroll bars but it doesn't work so well, the horizontal scrollbar doesn't change it's orientation, it doesn't change to a vertical scroll bar.</p>
  
  <p>How do I paint a completely new JScrollBar and use it within a <code>JScrollPane</code>?</p>
