Fixed order of operations problem when tearing down the window

Make sure the window framebuffer is cleaned up before shutting down OpenGL, as it might be implemented using an OpenGL texture.

Fixes this call stack:
```
(gdb) p _this
$1 = (SDL_VideoDevice *) 0x42e360
(gdb) p _this->egl_data
$2 = (struct SDL_EGL_VideoData *) 0x0
```
