  Log Message:
  -----------
  VisItPlotViewer can now reuse Resources

The VisItPlotViewer had previously always been using the VizResource for
the last plot added, preventing it from redrawing old plots. It now
keeps track of all used resources and will switch to the resource
matching the selected VizEntry before trying to draw the plot.
