Pointerlock erratic camera movements

[kkota1]

High polling rate (>250Hz) mouse = jumpy camera movements with some platforms

• A-Frame Version: all
• Platform / Device: Windows + chromium-based browser
• Reproducible Code Snippet or URL:

Root cause is an OS bug: https://bugs.chromium.org/p/chromium/issues/detail?id=781182

Workaround we successfully implemented in our fork involves checking for outlier values in look-controls.js component

    let x = evt.movementX || evt.mozMovementX || 0;
    if (Math.abs(x) > window.innerWidth/3) {x = 0}

    let y = evt.movementY || evt.mozMovementY || 0;
    if (Math.abs(y) > window.innerHeight/3) {y = 0}
