Shadered Plus

Shadered+ 1.0.2

New blocks
- Mirror: live reflections of the world, including mobs, you, block entities, Shadered sky blocks, Sky Islands
  and portals. Mirrors reflect each other endlessly, losing a little sharpness with each bounce. Works with
  Iris/Oculus shader packs (tested with Complementary), using the pack's lighting and shadows.
- Infinity Mirror: an endless tunnel of LED rings. Blocks side by side on a wall join into one big frame.
  Right-click to change colour (blue, red, green, cyan, pink, white, gold, animated RGB), sneak to go back.
- Infinity Cube: an endless 3D grid of LED edges seen from every side. Cubes filling a whole box join into one
  big cube. Same colours as the Infinity Mirror.
- 16 new sky blocks: Scadu Altus, Cerulean Coast, Gravesite Plain, Mountaintops of the Giants, Altus Plateau
  (day, sunset, night), Divine Tower, Caelid, Siofra River, Limgrave (sunset, rainy), Academy of Raya Lucaria,
  Liurnia (day, sunset, rainy). Each has its own Sky Liquid.

Portal skies
- Right-click a nether portal, end portal, end gateway or a modded portal with a Shadered sky block to show
  that sky inside it. Right-click with an empty hand to undo. The portal particles take the sky's colour.

Sky Islands
- Islands now show the Infinity Mirrors and Cubes inside them, the skies of portals inside them, and the
  island inside Island Paintings (on pedestal islands). Rescan old islands to get these.

Fixes
- Sky blocks no longer show lines or corners where the skybox faces meet.
- Infinity blocks stay steady while walking.
