Re: [PNG] Cancelling May 15th, 2023 meeting?

I'm fine cancelling Monday's meeting, but I would like there to be some 
discussion about what we need to do to publish an updated PNG Working 
Draft so that we can start TAG review.

I also suggest putting the content from your average luminance paragraph 
below into a GitHub issue, which is much easier to keep track of than email.

Agree that we should meet informally but that there isn't a pressing 
reason to hold a meeting at TPAC.
