[PNG] Likely cancelling meeting?

Hello everyone,

Monday, we have a meeting scheduled.
As usual, I don't want to cancel several in a row. That could look like no
progress is being made.
But I think we should cancel this meeting unless anyone objects.

For some progress on my side:
- I've gathered several public domain images that are perhaps typical PNGs.
I'm skeptical on the "typical PNGs" part. But right now I'm feeling like
beggars can't be choosers. Anyway, I'll bundle them and make them easy to
access. The goal is to have a corpus for things like comparison with other
image formats.
- I've been working on some HDR coding to go into ImageInternals, the test
bed for a bunch of these proposed PNG changes.
