title: in Qt 4.8 how to set "Qt::PreciseTimer"
body: <p>As the title says:
  I have this snippet:</p>
  
  <pre><code>QTimer timerdata;
  </code></pre>
  
  <p>I can start the timer by calling <code>timerdata.start(5);</code> However, I am not getting 5 msec...I know that in Qt 5.x there are three levels of precision for timers:</p>
  
  <ul>
  <li>Qt::PreciseTimer: About 1 ms resolution on Windows</li>
  <li>Qt::CoarseTimer (default): About 15 ms resolution on Windows</li>
  <li>Qt::VeryCoarseTimer: 1000 ms resolution on all platforms</li>
  </ul>
  
  <p>My question is is there something similar in qt 4.8 and if true, how to set it?</p>
