   # the 32-bit GCE bots run out of memory in DM when running these large images
   # so defensively disable them in nanobench, too.
   # FIXME (scroggo): This may have just been due to SkImageDecoder's
   # buildTileIndex leaking memory (https://bug.skia.org/4360). That is
   # disabled by default for nanobench, so we may not need this.
   # FIXME (scroggo): Share image blacklists between dm and nanobench?
