This improves the range of seeds compared to using only getMillis (which is the number of milliseconds since program start) as the seed. This was especially an issue if you started the game directly from command line, Steam, or GOG instead of using the ScummVM interface. Previously the initial seed was just the load time, which can have very small variance on a fast computer.
