title: How to enable VSYNC in OpenGL
body: <p>The WGL_EXT_swap_control extension allows doing this on Windows, but I am unable to find anything even remotely cross-platform doing the same, i.e. syncing my buffer swaps with screen refresh. My application uses GLEW, so something offered by that would be preferable. Cross-platform support for Linux, Mac and Windows is necessary, but my application will not break if the sync cannot be set (e.g. the user has forced it off in his graphics drivers).</p>
  
  <p>I will accept program code to do it on many platforms, with GLEW, as a valid answer.</p>
