Comment 1 for bug 1408707

This is a configuration change only. world/terrains/init.lua contains a dither_layer for each terrain. This value is compared when two terrains are adjacent and decides which one will be dithered over which other [1]. If both values are equal, no dithering is done. Making sure that not two values are equal in this file make sure that everything is dithered.
