Pixel Reality

• Finally added the Ender Dragon!
• Added a cute pink Saddle for piggies, the Lead knot, the Saddle icon.
• Added blank icons for missing server/save/resourcepack ones.

Tweaks

• Added much more variations to biome colors, also depending on height, especially notable if you use Amplified or otherwise very hilly worlds; things may change again in the near future according to something Grum said, but since I worked a lot on this, there you go.
• Completely redesigned the Sheep to be more sheepy, the Chicken, now with small chicken-like beaks, and the Zombie to better integrate with the new horrible Zombie Villagers; they look really rotten so pretend they're Villagers zombified so much time ago they can no longer be cured.
• Changed the color of ferns and arrows.
• Made glass more transparent and with stronger reflexes.
• Turned the Ender Crystal base into obsidian.
• Made rain a little more realistic.
• Took away unnecessary icons from the server/save selection.
• Cleaned a few items from "ghost" pixels.
• Made transparent particles a little less ugly when seen against transparent surfaces, reintroduced water drops from rain on blocks to make things a little more lively, and redesigned the water bubbles and the liquid drops from the ceiling.
