title: How to recover OpenGL buffers after minimization?
body: <p>Assume I made an application that uses SDL + OpenGL to display graphics. The scene is not dynamic so I do the drawing and swapping of the buffers once in a while.</p>
  
  <p>I observed that after minimization and bringing back of a window under Windows 7 the displayed content gets destroyed and random stuff is displayed. Is there any way I can recover it without repeating the last rendering?</p>
  
  <p>I'm using Windows 7 Proffesional SP1 with Intel G45/G43 Express Chipset.</p>
