 **Testing instructions**

 - Verify your WordPress install supports AVIF (check Tools-> Site Health
 -> Info tab -> (expand) Media Handling section. Either GD or Imagick must
 have "AVIF" listed.
 - Upload an AVIF image to a post or the media library. Some test images
 are available in
 [https://github.com/AOMediaCodec/libavif/tree/main/tests/data the libavif
 repository].
 - Test features like cropping and rotating in the media library and the
 editor
 - Test viewing post in all [https://make.wordpress.org/core/handbook/best-
 practices/browser-support/ supported browsers] (Browserstack would be
 great for that)
 - Test using the `image_editor_output_format` filter to output AVIF's for
 uploaded JPEGs, noting JPEG/AVIF file sizes with/without the filter.
