- Change the property name of the "distance" function from "argument" to "max" (the old works as a fall-back)
- Add an optional "min" argument to the "distance" function, default 0.0, has to be not bigger than "max"
- Fixes and tweaks to the Cauldron preset
Initial release with two density functions (distance, lerp) and three worldgen presets based on it (Single Continent, The Cauldron and Archipelago).
