Explainer: Font Metrics Override Descriptors

(A newer version is at here, where a new descriptor advance-override is added)

Spec

This doc explains descriptors ascent-override, descent-override and line-gap-override for CSS @font-face rule.

Basic usage:

/*
Copy this into the console of any web page that is interactive and doesn't
do hard reloads. You will hear your DOM changes as different pitches of
audio.

I have found this interesting for debugging, but also fun to hear web pages
render like UIs do in movies.
*/

const audioCtx = new (window.AudioContext || window.webkitAudioContext)()

//  Remove any duplicates from an array of primitives.
const unique = [...new Set(arr)]

// Sleep in async functions. Use: await sleep(2000).
const sleep = (ms) => (new Promise(resolve => setTimeout(resolve, ms)));
// or
const sleep = util.promisify(setTimeout);

// Nullify the transforms of the element
// 
// This is all behaving just like getBoundingClientRect() but it nullifies all the transforms
// and kinds _reverts_ the element onto its original position.
// This will work even with complex translations, rotations.
// The beauty is in the way it applies matrix inverse onto the transformation
// matrix and mutates the getboundingclientrect along the way.
//
// Usage:
// let { top, left } = nullifyTransforms(el);
