[pmwiki-users] RFC: AVIF format

[Petko Yotov]

I've added the AVIF and AVIFS file extensions as allowed attachments, 
and as image extensions to be embedded. This is now in Subversion and 
should be available for 2.3.32.

I'd advise wiki writers to test how their AVIF(S) pictures work in 
different browsers -- at least Chrome and Firefox.

While most reference files from a sample set[*] appear to work, some 
files with specific "profiles" (color spaces, depths) may fail, in 
either Chrome, or Firefox, or both.

I suspect these profiles target professional image processing rather 
than web publishing. Also browser support should hopefully improve with 
time.
