3D Vector Graphics DEMO (edge update)

• New culling algorithm to improve performance
  
• Fixed triangles with 1 or 2 vertices passing behind the player. Now displays accurately.
  
• Still somewhat broken draw order, I know what I would have to do to fix it but this time it's genuinely impossible to add.

Good luck dissecting this one. I've had to replace a lot of variable names with 2 or 3 character long acronyms in an attempt to reduce the character count as much as possible. Even with this, there's still no space left to add more stuff. At this point I would have to either completely rebuild the code in a more space efficient way (no thanks) or read through it (impossible now) and see if I can combine certain functions together or under the same loops (no thanks).
