[PNG] Cancel Monday's meeting?

Sorry about the late notice.

I don't think we have anything we need to meet about on Monday. The main
topics fall under "This could have been an email". So please take a look
and respond on GitHub if you have thoughts:

   - Chris Seeger has a pull request out to improve the mASt chunk and add
   the mLUm chunk <https://github.com/w3c/PNG-spec/pull/258> [1].
   - There is talk about renaming mASt to mDCv (Mastering Display Color
   Volume) <https://github.com/w3c/PNG-spec/issues/238> [2].
   - Pierra-Anthony Lemieux has a draft of requirements for a shared
   repository of test images.



If there are topics you would like to talk about, feel free to respond here.
