We round these values to four decimale places: This saves us on rounding errors on the client-side, which could theoretically increase our cache size when we hit them, and in the case of the left/top values, this also makes sure that we get the closest pixel value, not the integer of it -- this is important when we get around to requesting the tiles, since otherwise we end up a pixel off, and then we don't get our images back.
