6	# id: ore ID to spawn, the ID must exist on the ores.csv
7	#
8	# freq: frequency value used to set up noise generator. Larger = ore veins are closer together
9	# power: power value (as in: randomNumber ^ power) used to set up the noise generator. Larger = veins are larger as you go deeper. 0.01 almost negates this effect
10	# scale: scale value used to set up the noise generator. Larger = thicker veins. A valid value tend to play around the 0.5	you'll need figure out this value by trial and error
11	# ratio: how elongated (or squeeze) the ore veins are. >1.0 = stretched horizontally, <1.0 = stretched vertically
12	#
13	# tiling: determines how the tiles are tiled
14	# - a16: use 4-neighbour autotiling (16 possible cases)
15	# - a16x4: 4 variants of a16
16	# - a16x16: 16 variants of a16
17	# - a47: use 8-neighbour autotiling (47 possible cases)
18	# - r16: use the hash of the tile position as a variant selection, module 16
19	# - r8: use the hash of the tile position as a variant selection, module 8
