[PNG] Upcoming meeting topics

Hello everyone,

We have a meeting this coming Monday, the 19th. That is a holiday in the
US. There are some topics we could discuss. But they also fall under "that
could have been an email". So perhaps let's cancel the meeting but try to
make movements on these.


Here are some possible topics:

   - The spec currently has 4 ReSpec errors
   <https://w3c.github.io/PNG-spec/>. These are new so we can go through
   the history to find what introduced the errors and fix it.
   - There are 2 open pull requests. These have some changes requested in
   order to land.
   - There is 1 remaining issue marked as "blocking-3rd-edition-cr"
   <https://github.com/w3c/PNG-spec/issues?q=is%3Aissue+is%3Aopen+label%3Ablocking-3rd-edition-cr>.
   Really, it is more of a nice-to-have.
   - There are 3 remaining issues marked as "blocking-exit-3rd-ed-cr"
   <https://github.com/w3c/PNG-spec/issues?q=is%3Aissue+is%3Aopen+label%3Ablocking-exit-3rd-ed-cr>.
   Do these need action?
   - I still need to add cICP handling to libpng to ease adoption for users.


Feel free to reply here or on github.
Thanks!
