title: Need cross-platform GUI toolkit with OpenGL support
body: <p>I need a cross-platform GUI toolkit with OpenGL support. I also need to be able to draw on a canvas or panel from an image buffer. The candidates I've chosen so far are FLTK (it can do OpenGL windows -- I don't know about canvases), Qt, and wxWidgets.</p>
  
  <p>Any idea which would be the best?</p>
  
  <p>Thanks!</p>
