        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.

        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.
