change: examples common code

[eviltik]

Plenty of code in examples can be stored in one js class witch can be extended :

App:

• constructor
• initScene
• setupXR
• resize
• render

Final code example:

import { Environnement } from '../Environnement.js';
import { CanvasUI } from '../../jsm/CanvasUI.js';

class App extends Environnement {
    constructor() {
        super();
    }

    createUI() {
        ...
    }

}

The Environnement class will have little methods like setupRenderer, setupCamera, so we can override methods in the main class easily.

@NikLever will you accept this change ?

I don't want to leave users feeling they need to use a helper class with CanvasUI. So on balance I don't like the idea. But you could convince me. BTW Environnement is spelt Environment in English. Probably best to use the English spelling.

I can understand ! It's more easy for users.

Wont fix.
