ScatterPlot fails to generate vector image

In the Viz showcase example, the ScatterPlot fails to generate vector image.

It seems to me that the last parameter 'generateVectorImage' of the constructor public ScatterPlot(int resolutionX, int resolutionY, Envelope datasetBoundary, boolean reverseSpatialCoordinate, boolean generateVectorImage) is ignored at the ScatterPlot class level and at the superclass VisualizationOperator level.

The constructor public VisualizationOperator(int resolutionX, int resolutionY, Envelope datasetBoundary, ColorizeOption colorizeOption, boolean reverseSpatialCoordinate,
            int partitionX, int partitionY, boolean parallelPhotoFilter, boolean parallelRenderImage, boolean generateVectorImage) does not handle the parameter 'generateVectorImage' at all.

I am working with commit 0a6f26a0e0eace87243dd919738af5f182557b8a
