Re: Unofficial pngcheck now with APNG support

It would be useful if the generated tests had a similar license to the
generator; the generator seems to be "unlicensed" but the tests are not,
they simply don't have any license individually and the directory itself
doesn't have a LICENSE or any other information.  My recommendation is to
embed the license text in the PNG itself, along with the copyright; it's
not hard!  In general for original content like this I think I recommend
the "GPL Free Documentation License" (it's content therefore it is
"documentation") but share-and-share-alike is a possible alternative.
