CPU Rasterizer in JavaScript

EASEL.js exposes a CPU rasterizer for JavaScript scenes that need depth-tested opaque pixels, sorted transparent draws, scanline fill, and Canvas2D framebuffer output.

Rendering constraints

EASEL.js keeps software-rasterizer limits explicit instead of masking them. The result is a focused fit for retro rendering, debugging, and deterministic CPU-side control.
