Description:
------------
I know the support is still almost inexistant.... Just supported in Windows10 since May, and no browser supports it atm, as far as I know. (There is however a polyfill : https://github.com/Kagami/avif.js)
But the AVIF format was born earlier this year, and support will probably arrive soon everywhere (AOM initiative, from google, mozilla, apple, etc...)
The promise of this format is big, and it should - finally - be a real replacement for our current outdated formats (jpg, ..).

avif spec : https://aomediacodec.github.io/av1-avif/

GD is actually a separate project from PHP.

PHP has bundled libgd so it could use update to https://github.com/libgd/libgd/releases/tag/gd-2.3.2 which added AVIF & HEIF support

The nice thing is that desktop Chrome, Firefox, and Opera now support AVIF, at least for single images (not animations):

I assume Chrome for Android support is on the way, and since this work has involved many companies, I don't think we'll have to wait as long as we did for WebP for other browsers.

Talking to PHP core maintainers this weekend, I learned that PHP's GD is a fork of libgd. So we need to adapt the new gd_avif.c (https://github.com/libgd/libgd/blob/master/src/gd_avif.c).

Tiny update: just learned that Chrome for Android does in fact support AVIF as of version 89. That brings the share of users whose browser supports AVIF up above 60%.
