      - Support for reading PDFs where the owner and user passwords
        are different

      [FIXES]
      - setpdfbackground.pl computed RGB values incorrectly.  Thanks to
        Andrew Cadman for finding the bug and suggesting a fix

1.12  27 Nov 2007
      [FIXES]
      - I just realized that CAM::PDF::Renderer::Text was useless
        because it just printed to STDOUT.  Fixed to offer a
        toString() method instead.  Fuse::PDF wants this feature.
      - Fixed a typo in the Synopsis of CAM::PDF::Content

1.11  20 Nov 2007
      [ENHANCEMENTS]
      - added previousRevision() and allRevisions() [invented in Fuse::PDF]
      [INTERNALS]
      - Compliance with Perl::Critic v1.080
