Couriersud fixed bug #603
Using the following sequence
SDL_Init(..:)
SDL_CreateWindow(..., SDL_WINDOW_OPENGL)
SDL_DestroyWindow
SDL_CreateWindow(..., SDL_WINDOW_OPENGL)
SDL will crash in X11_GL_GetVisual. This is due to the fact that
during SDL_DestroyWindow X11_GL_Shutdown was called because the last window
has been closed.
On the next call to SDL_CreateWindow the library is still loaded and only the
memory is reinitialized. Function pointers such as gl_data->glXChooseVisual
will not be reinitialized.
Consequently, SDL will crash due to a NULL pointer access.
The attached patch corrects the behaviour.
