We can easily accumulate a large number of in-memory graphic objects, and swapping these as well as the un-compressed images can become important. For now we swap out the container when the image is swapped out, however it seems unlikely it will ever need to be swapped in again. Despite the shared pImpl, we retained the reference counting on the underling vector to keep this immutable while we hand out a MemoryStream reference to it.
