C Supported device: Canon LaserShot (LIPS2/2+).
C Conforms to ISO646,2022,2375 and 6429 specifications.
C VDM (graphics) conforms to proposed American National
C Standard VDM mode.
C
C Device type code: /LIPS2 (landscape, mode 1)
C /VLIPS2 (portrait, mode 2).
C
C Default file name: PGPLOT.LPS
C
C Default view surface dimensions:
C 23 cm by 18 cm (landcsape)
