Rustling Leaves

Brings the Minecraft 1.20.1 version up to Rustling Leaves 2.8.0 (also 2.6.0 and 2.7.0).

Added

• Leaf sounds of their own, cut from real field recordings: a dry crunch and swish when you walk through leaves, soggy steps in wet leaves after rain and the scrape of a rake. They replace the borrowed block sounds.
• Conifers drop needles: spruces, pines, firs and other conifers shed a small needle sprig (three shades, with its own shadow) instead of the broad leaf. Under them lies a rusty carpet of mostly brown, dead needles that covers the forest floor almost everywhere instead of in a few thin patches.
• Leaves blow the way the rain slants with Petrichor: Rain & Storms and the way the snow drifts with Hoarfrost: Snow & Blizzards. Their gusts, squalls and whirlwinds stay. The option leaves.livingWind now covers these mods too.
• Client option leaves.placedLeaves: leaves placed by players (hedges, leaf roofs, decorations) no longer shed leaves or get a leaf carpet under them, so builds stay tidy. Turn it on to have them shed like trees.
• Shader packs can sway with the leaves' wind: while an Oculus shader pack is on, the mod hands its wind and gust waves to the pack every frame (rustling_leaves:shader_data, a small data texture any pack can read). Pocky Shaders bends grass and tree crowns with the very gusts that blow the leaves off.

Changed

• Shader packs see falling leaves as leaves: with an Oculus shader pack, leaves in the air are shaded the way the pack shades the tree crowns, glowing gold and red when a low sun shines through them.
• New textures for leaf carpets and piles, strewn from the same small leaf sprites as the falling leaves. With leaves.oldLeafTextures the piles get their old textures back too. Fewer leaves stick up from piles, and less steeply.
• Cleaner autumn colors: leaves that turn go all the way to golden, amber, orange, red or a warm brown instead of olive and khaki. Softer shading on the ground: deeper leaves, the sides of piles and the shadows around them are lighter, so litter no longer looks smudged.
• Falling leaves are no longer darkened twice with a shader pack, and without one a leaf turned sideways is only a little darker than one lying flat.
• The pixel shadows of falling leaves fall the same way as the shadows of a shader pack that tilts the sun's path (BSL, Complementary Unbound and others).

Fixed

• No more short stutters caused by the leaf litter: the game froze for 50-70 ms every half minute while the litter was saved, and for up to 100 ms after joining a world or teleporting while it was loaded. Saving and loading now go a little at a time and the files are read in the background.
• Leaves floating on the water no longer sink into it with shader packs whose water moves in waves (BSL, Photon, MakeUp and others).
