[PNG] Meeting topics for July 10th, 2023

Hello everyone,

I apologize for the late email.

Topics for our July 10th meeting:

   - Can we close GitHub issue 126
   <https://github.com/w3c/PNG-spec/issues/126>? Should we first reference
   "implementation-defined" and add it to the places mentioned in GitHub
   pull request #172 <https://github.com/w3c/PNG-spec/pull/172>?
   - GitHub pull request #321 <https://github.com/w3c/PNG-spec/pull/321>
   addresses GitHub issue #158 <https://github.com/w3c/PNG-spec/issues/158>
   by detailing the possibility of unused trailing bits at the end of the
   final IDAT chunk. Any changes requested?
   - GitHub issue #323 <https://github.com/w3c/PNG-spec/issues/323> is a
   Call for Consensus to publish an updated Working Draft. Once the above two
   issues are addressed, there are no technical changes left for the Third
   Edition. An updated Working Draft would put us in a good position for the
   coming TAG review.
   - GitHub issue #320 <https://github.com/w3c/PNG-spec/issues/320>
   mentions we should add a test case for ancillary chunks outside ISO 646 A-Z
   and a-z range. Is anyone interested in taking this on?


Thanks!
See you at the meeting.
