There are currently 9 conditions:\n* `biome` checks if the biome at the location is one of the given biome IDs in the array `biome_is`.\n* `hole`\n* `noise_threshold` checks if the value of a noise using `name` and `noise` is between `min_threshold` and `max_threshold`.\n* `not` inverts the surface condition in field `invert`.\n* `steep`\n* `stone_depth` checks for hitting the depth of stone.
