Controlled by image.animated.decode-on-demand.threshold-kb, default 256MB Includes squashed bugfixes/regressions: - m-c 1444537: Shutting down the decode pool should make animated decoders bail early - m-c 1628606: Make sure to mark the surface cache entry available before sending the frame complete notification - m-c 1502275: Skip recreating the decoder after redecode errors if an animated image is reset - m-c 1443232: Don't insert frames into our AnimationFrameBuffer that we consider in error and unusable
