Bug 1368776 - Part 15. Cache flags passed to ImageResource::GetImageContainerImpl for consistency. r=tnikkel
When FLAG_HIGH_QUALITY_SCALING is used, we need to make sure we continue
using that flag when we update the container. We should also use it for
comparing whether or not an existing image container is equivalent.
