  Fixed bug 3605 - Software renderer no longer renders after Android screen orientation change
  
  Sylvain
  
  This still happens with the current trunk version.  (software renderer of testdrawchessboard.c)
  
  When there is a rotation, the window size changed and the internal surface is marked as "surface_valid == SDL_FALSE".
  And all further call fails.
  
  SDL_video.c :
  
  2478 void
  2479 SDL_OnWindowResized(SDL_Window * window)
  2480 {
  2481     window->surface_valid = SDL_FALSE;
  2482     SDL_SendWindowEvent(window, SDL_WINDOWEVENT_SIZE_CHANGED, window->w, window->h);
  2483 }
  
  some error set to :
  2233         return SDL_SetError("Window surface is invalid, please call SDL_GetWindowSurface() to get a new surface");
  
  
  So, this seems to be the behavior of the API ...
  
  
  In the loop() function of testdrawchessboard.c, we can recreate the surface/renderer :
  
   65        if (e.type == SDL_WINDOWEVENT)
   66        {
   67             if (e.window.event == SDL_WINDOWEVENT_SIZE_CHANGED)
   68             {
   69                surface = SDL_GetWindowSurface(window);
   70                renderer = SDL_CreateSoftwareRenderer(surface);
   71             }
   72             /* Clear the rendering surface with the specified color */
   73             SDL_SetRenderDrawColor(renderer, 0xFF, 0xFF, 0xFF, 0xFF);
   74             SDL_RenderClear(renderer);
   75        }
  
  And it displays correctly.
