Bug 1465619 - Part 10. Re-add support for discarding animated image frames. r=tnikkel AnimatedFrameDiscardingQueue subclasses AnimationFrameBuffer to allow a cleaner abstraction over the behaviour change when we cross the threshold of too high a memory footprint for an animated image. The next patch will build on top of this to provide an abstraction to reuse the discarded frames. Differential Revision:
