Re: [PNG] Meeting topics - Jan 6, 2025

Oh! There is another bit of good news.
I found out there is a way for the public to access specific Chrome usage
stats
<https://chromium.googlesource.com/chromium/src/+/HEAD/docs/use_counter_wiki.md>
.
So I can write some Chrome code to check for malformed PNGs or PNGs with
"mDCv" (old name), as examples.

I'm going to add checks for mDCv/mDCV & cLLi/cLLI soon.
