title: opencv - resizeWindow do nothing?
body: <p>I tried  some variations but it seem that resizeWindow don't do anything.
  I give simple code example,the result is that the 2 windows are in the same size , eventough it supposed to be in different sizes.</p>
  
  <pre><code>Mat m = imread("somePath",CV_LOAD_IMAGE_COLOR); 
  namedWindow("aa",CV_WINDOW_NORMAL);
  namedWindow("bb",CV_WINDOW_NORMAL);
  imshow("aa",m);
  imshow("bb",m);
  resizeWindow("aa",400,400);
  resizeWindow("bb",800,800);
  waitKey(0);
  </code></pre>
  
  <p>I work  with eclipse-cdt on ubunto 12.04 with opencv 2.4.3.</p>
  
  <ul>
  <li>I tried to debug it,getting into the the function but I don't succeed to add highGui modoul  as external source, i get compile error of some h file missing.</li>
  </ul>
