Add a web platform test for APNG While animated-png.html uses internals for selecting frames and verifying that we decode APNGs properly, this test confirms that a basic animation will work correctly, and can work in other browsers. - apng.png A simple APNG with two frames. The first frame is red, and displays for as short a time as possible (11 ms; anything less than that and Chromium increases the time), followed by a green frame. The image does not loop. The green frame matches green.png, which already exists - animated-png-timeout-ref.html Reference page showing the existing image (green.png).
