Add plantlike_rooted coral

[Ezhh]

This:

• Adds three new plantlike rooted corals (green, pink and cyan) using textures from the sea modpack.
• Removes the existing coral schematic.
• Switches coral placement to simple single node placements.

This is very much WIP.

In its current form placement looks like this:

Please note that noise needs to be adjusted and in this example I've set it to place huge amounts of coral just so we can get an idea of what it might look like.

To do:

• Better noise values.
• Fix any other problems.

Closes #2040

Now that's a very lovely decoration for the sea grounds. I'm looking forward to have this feature in MTG.

Coral textures need to be indexed alpha.
In testing digging and placement are fine, not sure what's best for placement prediction.
Will work on noise params next.

[paramat]

		sidelen = 4,
		noise_params = {
			offset = -6,
			scale = 4,
			spread = {x = 100, y = 100, z = 100},
			seed = 7013,
			octaves = 3,
			persist = 1,
		},

Note sidelen 4.
This is fairly similar to previous distribution and rarity.

I'm neutral.

Using the noise values suggested by @paramat, there are some very nice patches such as:

But also found a weird square patch I am not so keen on. Unsure how common this might be.

[Ezhh]

Not really WIP anymore, but still open to suggestions for changing drops and groups for the coral.

[paramat]

Yes the noise is tricky, the square area is due to the 3rd octave of noise spiking up. I need to tune more, but i'm thinking merge anyway, tune later?
👍 but has a conflict.

[paramat]

Well, i'm neutral, you can merge if you want, or wait, i'll get working on tuning noise.

[Ezhh]

I'm fine with merging and then you can look at adjusting more later. I only found that one area in the screenshot so far that didn't look good to me, so it's possible that it's rare.

One thing I would like an opinion on first is the groups.

[paramat]

'cracky = 3' seems maybe a little too much effort for thin fragile coral structures, being equal to a full stone node.
Looking at papyrus and other plants, how about 'snappy = 3'? These corals seem similar to snappable plant stems.

[Ezhh]

That's what I am leaning more toward, it's just a bit odd when you have the combined structures due to the nature of the drawtype.

[paramat]

Ok. but when dug only the top extension is dug.

[Ezhh]

Yes, why I'm leaning toward it. Will change.

2000x2000 map. Orange pixels in sea sand are corals (water not visible).
Finer detail noise. Persistence 0.7 instead of 1 so shapes are a combination of a larger variety of scales. The shapes seem more interesting instead of squarish blobs.
Note the map is all hot biomes so this is the distribution within hot biomes.

		sidelen = 4,
		noise_params = {
			offset = -4,
			scale = 4,
			spread = {x = 50, y = 50, z = 50},
			seed = 7013,
			octaves = 3,
			persist = 0.7,
		},

[Ezhh]

Okay, rebased due to conflict and updated noise (I think that looks much better).
