class Driver from CGM inherits PlotterDriver from PlotMgt
---Purpose: This class defines a CGM (Computer Graphic Metafile) plotter Driver.
--- All necessary information about methods (purpose, level, category, etc.)
--- can be found in CDL files from the inheritance tree (PlotMgt_PlotterDriver,
--- Aspect_Driver).
