                        NOTICE: It takes at least 1000 instability to ruin a world. Since we have random
                        worlds, that's another 275-325. This should put us well into the meteors, flames,
                        crumble, etc -- this should give the world falling apart around us, without decay
                        blocks.
                        EEEEK! Was 1500, but that gave waay too much. Toned down significantly. Hmm ...
                        New setting: 750, which just puts random worlds over 1,000.

                <Comment> Surprise, surprise! Meteors plus blue can be seen at 600!
                          This realy might be high. </Comment>

                        Modification of emerald for decay blocks. Adjusts until we get something that works.
                        Idea is single block deposits, fairly rare.

                <Comment> Black decay doesn't work well. It is slow. Almost no spreading.
                          There are only tiny decay pockets before white swallows it all.
                          Maybe if it can generate larger starting stuff, like a vertical
                          ellipsoid, so it can fall over a larger area ...
                          I like that idea. I *really* like that idea. Each block is slow
                          but it has enough of a head start to be able to have an effect.
                          I think this idea is obviously well-justified, and you can tell
                          by using a fixed-point font to read this paragraph.

                <Comment> TODO: Higher spread range in hilly biomes
                                Lower spread range in "water" biomes
                                Rivers (55) vs oceans (42) vs normal (66) vs ...

                                Sadly, you cannot use the height of the noise function cutoff.
                                "Biome height levels" does not work for small/tiny biomes, and
                                lacking vanilla's transition biomes, does not work for large
                                height differences next to each other.
