[PNG] Cancel meeting?

Hello everyone,

I'm working on making a clear list of PNG Fourth Edition requirements & use
cases.
We have completed the negative cHRM values.
We are waiting on:

   - gain maps
      - ISO 21496-1 is not yet free. Liaison established
   - gain curves
      - SMPTE 2094-50 is not free, but we are probably waiting on AOM's
      version anyway
   - T.35
      - This is freely available. I think this is tied to gain curves, so
      also waiting?
   - rWTm
      - ISO/TS 22028-5 is not freely available, so we'll need liaison work
      here, too


Given that list, it looks like we're almost entirely waiting on other
specs. If we wanted, we could try to get ahead of things. But that could
also backfire if a spec is not made free or if the AOM version is slightly
different.

Given that, I'm in favor of cancelling meetings until we are unblocked.
Thoughts?
