Bug 1821357 [wpt PR 38906] - Add tRNS PNG test, a=testonly
Automatic update from web-platform-tests
Add tRNS PNG test (#38906)
* Add tRNS PNG test
The PNG spec Third Edition clarified that high bits of a tRNS chunk should be
ignored on a lower bit depth image. Previous editions were unclear,
which caused divergent behavior.
This commits adds a PNG image which contains a tRNS chunk with non-zero
values in its high bits. This commit also adds a test to verify these
high bits are ignored.
* Address code review comments
Updated title, added help link, and made the image a relative link.
