Values can be between [-32768, 32767], with positive numbers resulting in a sky that scrolls from
west to east, and negative numbers resulting in one that travels east to west.

Please note that speeds outside of the range of about [-1000, 1000] will cause the
sky to scroll so fast that it will no longer appear as a coherent stream of clouds.
Less is more. City of The Dead, for example, uses a speed value of 16.
