    To see this work, compare ClarityOCGs.pdf with and
    without this change.
    Right now we only handle optional content using
    XObjects. Optional content using Marked Content has
    infrastructure, but is not implemented. That will be
    quite invasive in Gfx, and I'm not confident enough
    to do it this late in the process.
