              Updated the core content parser and graphic stack to have basic support for transparency groups. Knockout parameters and the grouping mechanism seems to be working however the isolation group is a little harder to nail down. As more examples come in I can improve the transparency model now that I have a better understanding of how the specification works for grouping.

              ICEsoft Public SVN Repository #21758 Fri Jun 18 07:33:20 MDT 2010 patrick.corless PDF-160 implemented a strategy for handling group transparencey. Knock transparency is support and partial support for isolation but can't be sure until we have more examples.

              In the original PDF groupped transparent circles are shown with differnt
              settings.

              ICEpdf seems to render them all the same way.

              Especially the small full transparent circle intersecting the red an green one
              on the left side does not show up in the ICEpdf rendered view.
