Remarks
This routine should only be used if you started DPlot with DPlot_Start and the was_active value is returned as 0, indicating that DPlot was started by your application. Otherwise you risk annoying users of your program who might have opened DPlot for other purposes. DPlot_Stop will only shut down DPlot if 1) DPlot is currently hidden or 2) if all open document windows are empty (regardless of the source of those documents).
