Wakes & Things

 Added
  - Silhouette glow: a soft glow around the outline of whole objects like trees and mobs. It never shows through walls.
  Strength is adjustable.
  - Clear biome-tinted water: much longer underwater visibility and more vivid biome water colour.
  - Rainbows appear after rain when the sun is low.
  - Distant bird flocks fly in V-formations by day.
  - Tapered shooting stars at night.
  - Swimming mobs now leave wakes like swimming players do.
  - Bushes, grass and leaves now react to nearby moving mobs and other players, not just you.

  Improved
  - Boat wake is now a widening V with an extra outer wave.
  - Underwater caustics are much brighter and more visible.
  - Bloom is stronger and softer at all levels.
  - Auroras have four ribbons, six colour bands and sharper animated rays.
  - Foliage sways side to side across the wind, with different motion for leaves, grass, flowers and vines.
  - Falling leaves glide and roll more naturally.

  Fixed
  - Release builds no longer fail because of a non-executable gradlew.
