// Work around a bug in the proprietary Linux ATI driver (at least versions 8.16.20 and 8.14.13).
// The driver appears to register its own atexit hook on context creation.
// If this atexit hook is called before SDL_Quit destroys the OpenGL context,
// some kind of double-free problem causes a crash and lockup in the driver.
// Calling SDL_Quit twice appears to be harmless, though, and avoids the problem
// by destroying the context *before* the driver's atexit hook is called.
// (Note that atexit hooks are guarantueed to be called in reverse order of their registration.)

// End work around.
