Detailed Description

This class implements the functions required to draw to a PostScript file.
This class is required because JEPSPrinter cannot inherit from JPagePrinter.

To generate postscript output beyond what is provided by this class,
create a derived class.  Inside each customized function, call
GetOutputStream() to get the output file and then write directly to it.
You *must* our functions whenever possible, because otherwise, you will
destroy our buffered values, and the results will be unpredictable.

Derived classes must implement the following functions:

    PSGetOrigin
        Return the current JPainter origin.

    PSResetCoordinates
        Set the origin and page size.

    PSGetPrintableHeight
        Return the height of the printable area.  This is used to
        transform screen coordinates into PS coordinates.

    PSShouldPrintCurrentPage
        Return false if the drawing commands should do nothing.

    PSPrintVersionComment
        Print the first line in the PostScript file.

    PSPrintHeaderComments
        Print any required header comments.

    PSPrintSetupComments
        Print any required setup comments.
