Description:

            SUBROUTINE PGSAVE
      
       This routine saves the current PGPLOT attributes in a private storage
       area. They can be restored by calling PGUNSA (unsave). Attributes
       saved are: character font, character height, color index, fill-area
       style, line style, line width, pen position, arrow-head style, 
       hatching style, and clipping state. Color representation is not saved.
      
       Calls to PGSAVE and PGUNSA should always be paired. Up to 20 copies
       of the attributes may be saved. PGUNSA always retrieves the last-saved
       values (last-in first-out stack).
      
       Note that when multiple devices are in use, PGUNSA retrieves the
       values saved by the last PGSAVE call, even if they were for a
       different device.
      
       Arguments: none
