basic window

★☆☆☆by Ramon Santamaria (@raysan5)

Runs the Zig port in your browser (WebGL 2).

Is it the same as C?

Desktop:verified The Zig version renders a final frame that is byte-identical to the C example.
Browser:verified In headless Chrome, the Zig version gives a final frame byte-identical to the C example built for the web.
