plgvpd - Get viewport limits in normalized device coordinates

p_xmin (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the lower viewport limit of the normalized device coordinate in x.

       p_xmax (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the upper viewport limit of the normalized device coordinate in x.

       p_ymin (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the lower viewport limit of the normalized device coordinate in y.

       p_ymax (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the upper viewport limit of the normalized device coordinate in y.
