I believe the patch that I just posted to bug #441971 will fix some of the errors in displaying the page listed in the description.

It would be nice if that page could be revised to also say what is expected from non-APNG-aware decoders.

The v1 patch to bug #441971 does indeed fix the "other depths and colour types" tests, at least on Windows XP.

Also on Windows Vista, these tests are cleared.

In fact, I reported this bug to be fixed bugs like bug #441971.
