Chunkscope 0.4.0

The Nether, and ruined portals.

What's new

• The Nether. A dimension switch next to the seed shows the Nether's
  biomes (Nether wastes, crimson and warped forests, soul sand valleys,
  basalt deltas) with their own colors and layers. Biomes, terrain and
  every Nether structure are computed exactly like the game:
  • Fortresses and bastions (they share one structure set: each
    attempt becomes one or the other);
  • Nether fossils, at the height the game picks from the terrain;
  • Ruined portals in the Nether.
• Ruined portals are now checked in the Overworld too, in every
  variant (on land, partly buried, underground, in mountains, on the ocean
  floor, in deserts, jungles and swamps). They are no longer marked as
  "possible": the map shows only the portals that really generate, and the
  inspector gives the height they start at.
• The seed finder searches Nether structures, for example "a fortress
  within 300 blocks of the Nether's 0, 0" together with Overworld filters.
  Nether filters are measured from the Nether's 0, 0.
• Only mineshafts are left unchecked (planned for 0.6).

Every new piece is verified against the real game, bit for bit, by the
oracle tests: Nether biomes at 4,800 points, the Nether terrain, and every
Nether structure attempt and generation point on several seeds, plus ruined
portal generation points in both dimensions.

SHA256SUMS.txt lists the checksums. The binaries are not signed yet: on
Windows, SmartScreen may ask for confirmation ("More info", then "Run
anyway"); on macOS, run xattr -d com.apple.quarantine chunkscope first.
On Linux the app needs the usual X11 or Wayland libraries.
