title: drawpoly() with float coordinates
body: <p>How to use <code>&lt;graphics.h&gt;</code> function <code>drawpoly(int numpoints, int *polypoints)</code> with array of float coordinates?</p>
  
  <p>(I guess that's the reason polygon degenerates rotating or zooming)</p>
  
  <p>Or do I need to make a function which draw a polygon with standard <code>line(...)</code>-function?</p>
