Espose Zdog.TAU

[vuchl]

Having the constant exposed for easier rotation handling would be useful

I don't see really why you would want that. To me, this is out-of-scope, I'm going to close this one. Feel free to tell me your use case anyhow

[vuchl]

From here: https://zzz.dog/api#utilities-tau

A full rotation in radians. Math.PI * 2. TAU is more user-friendly than PI as TAU maps directly to a full rotation.

const TAU = Zdog.TAU; // easier to read constant

rotate: { y: TAU/4 } // /4 = quarter turn
rotate: { y: TAU/2 } // /2 = half turn
rotate: { y: TAU*3 } // *3 = 3 full turns```

If you won't add it it's no big deal just thought it would generally bring more of the surface of Zdog to the wrapper library.

If you use it extensively in templates, it is easy to expose that yourself :
Vue.prototype.TAU = Math.PI * 2
I'd rather left that in userland.
