Summary:                    Legend in vtkPlotStracked shows the same color for
all entries
Description: 
I am drawing a vtkPlotStracked where the colors are set using a vtkColorSeries.
All colors displayed in the legend are the same. The color that is displayed
matches the color I would expect for the last entry (see the attached
screenshot).

The code for the PaintLegend method reads
bool vtkPlotStacked::PaintLegend(vtkContext2D *painter, const vtkRectf& rect,
int)
{
   painter->ApplyPen(this->Pen);
   painter->ApplyBrush(this->Brush);
   painter->DrawRect(rect[0], rect[1], rect[2], rect[3]);
   return true;
}

shouldn't this be 

bool vtkPlotStacked::PaintLegend(vtkContext2D *painter, const vtkRectf& rect,
int legendIndex)
{
  if (this->ColorSeries)
  {
    this->Brush->SetColor(
          this->ColorSeries->GetColorRepeating(legendIndex).GetData());
  }
  painter->ApplyPen(this->Pen);
  painter->ApplyBrush(this->Brush);
  painter->DrawRect(rect[0], rect[1], rect[2], rect[3]);
  return true;
}
