      SUBROUTINE GRSETLI (IN)
C
C GRPCKG: Set the line intensity for subsequent plotting on the current
C device. *** OBSOLETE ROUTINE *** Intensity is now set with GRSCI
C and GRSCR. For compatibility, GRSETLI now sets color zero if its
C argument is 0, and resets the previous color if its argument is
C non-zero.

C Argument:
C
C IN (integer, input): the intensity to be used for subsequent
C       plotting on the current device (in range 0-3).
