Fixed bug 2172 - Window loses maximized state when activated

I still haven't figured out why my application is being minimized when I try to raise, it but my previous workaround is causing issues.

For now the correct way to raise and/or restore the window is as follows:

	if ( !(SDL_GetWindowFlags( window ) & SDL_WINDOW_MINIMIZED) )
	{
		SDL_RaiseWindow( window );
	}
	if ( SDL_GetWindowFlags( window ) & SDL_WINDOW_MINIMIZED )
	{
		SDL_RestoreWindow( window );
	}

I will investigate the window state change rules more fully in the future.
