Rendering glitch in Beta 1.7.3

Rendering Glitch in Beta 1.7.3 was a bug, that broke block rendering. This glitch was in OptiFine from Beta 1.7.3 to Release 1.1 where it was fixed.

Glitch foundation
The glitch starts from around 10,000 blocks from spawn, where snow breaks down and starts to render incorrectly. At 20,000 blocks from spawn, transparent blocks start to render incorrectly and the world starts getting jittery, and 50,000 blocks from spawn, all blocks start to render worse and they start flickering, but not bad enough to crash the game or make it unplayable. From 300,000 blocks, players will have problems with rendering which can cause some blocks to not render. The player will have problems with camera movement.

After travelling 1,000,000 blocks from spawn, the rendering is so broken that the game will be unplayable (or in this case, OP haves a potato, my 9800 GT could handle this lol). The further distance your travel from spawn, the more broken the rendering will be. When players fly enough far away from spawn (500,000,000 blocks), it will start to render blocks in front of the player, even if the player is above terrain or height limit.

1 billion blocks (1,000,000,000) from spawn, blocks that normally shouldn't be seen will be rendered. Everything will be extremely distorted. The terrain finally stops rendering after the 32-bit integer limit, and the game will instantly crash or freeze. However, if the player teleport past 32-bit integer limit, everything will work normally but there won't be any terrain.

Z-axis
Z-axis is more broken and distorted. It will break so much, that blocks will deform with random rotations or anything like that when the player is near the Far Lands.
