Custom dimension/dimension type


 * (Boolean): Can be true or false. Whether the dimensions behaves like the nether (water evaporates and sponges dry) or not. Also causes lava to spread thinner.
 * (Boolean): Can be true or false. When false, compasses will spin randomly. When true, nether portals can spawn zombified piglins.
 * (Boolean): Can be true or false. Determines whether the dimension is treated as eight meters per block like in the Nether.
 * (Boolean): Can be true or false. Whether the dimension has skylight access or not.
 * (Boolean): Can be true or false. Whether the dimension has a bedrock ceiling or not. When true, causes lava to spread faster.
 * (float): How much light the dimension has, default is 0.5 in the demo file (for upper and lower bounds as well as precise effect).
 * (Boolean or integer; optional): Can be false or any integer from 0 to 24000. If this is set to a number, the time of the day will always be the specified value. However, in at least some worlds, false is interpreted as 0, giving constant sunrise. To ensure a normal time cycle, leave the attribute undefined (i.e, do not include it).
 * (string; optional): Can be FuzzyOffsetConstantColumnBiomeZoomer (used in the Overworld) or FuzzyOffsetBiomeZoomer (used in the nether and the end).
 * (Boolean; optional): Can be true or false. Whether the dimension has an ender dragon boss.
