Part 2: Tyrian City

[codenameyau]

Having done Obsidian City, I want to reflect and start part 2, Tyrian City. This will be a new repository.

Here are primary goals:

• Use playground.js as my core engine.
• Create a rectangular street grid.
• Street lighting.
• Step-by-step rendering.

Improvements:

• Better lighting and background scenary.
• Faster and more efficient rendering.
• More efficient window textures.
