      Description

      Take http://javafx-jira.kenai.com/browse/RT-5069
      "Text node computes complete text layout, even if clipped to a much smaller size"

      clipped could mean via a clip node, or it could mean scrolled off the visible portion of the window.
      We can detect the former, but the PGNode has - ie NGText in this case - has no idea how
      much work can be skipped. We could use a device clip so that when we have a Graphics
      instance we know what rendering work can be skipped.
