@jensimmons not so stoked about HEIC support because of the licensing situation around it, which will prevent other WebKit ports from shipping it and cause web compat problems; but yay for JPEG-XL support and hoping Chromium and Firefox follow. We should probably enable by default the support in the GTK and WPE ports.

On a related note, it would be good to get rid of JPEG2000 support, this ended up stagnating: https://github.com/WebKit/WebKit/pull/3824
