Fixed bug 1919 - Window icon disappears as soon as a renderer is created

Sebastian

Setting a window icon works just fine until a renderer is added to the window.
After adding the renderer the icon disappears.

Reproduce by:
- Take the example code from the wiki: http://wiki.libsdl.org/moin.fcg/SDL_SetWindowIcon

- Add the following two lines after SDL_FreeSurface(surface);
SDL_Delay(1000);
SDL_Renderer* ren = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);

-compile and run

You will see the window icon correctly at first. After the Delay the Icon will disappear.
