Re: Unofficial pngcheck now with APNG support

Good point.

The generator is in Web Platform Tests:
https://github.com/web-platform-tests/wpt/tree/master/png/apng/resources

as are (a subset of) the generated images, and the html files used to 
make them into reftests:
https://github.com/web-platform-tests/wpt/tree/master/png/apng

The entirety of WPT is under 3-clause BSD
https://github.com/web-platform-tests/wpt/blob/master/LICENSE.md
