In bug 1262549 it was noticed that we can run into OOM on Linux when trying to decode a GIF which requires a large deinterlacing buffer because even though we use fallible allocation, overcommit prevents this from helping us avoid OOM. In that bug the problem got fixed by using SurfaceCache::CanHold() as a heuristic to limit the size of the buffer.
The PNG decoder also has a deinterlacing buffer. Let's use the same heuristic there.

More likely to OOM in animated GIF but probably a good idea to have PNG match here.
