C CVSTATE:  Graphics Library CURVE state information
C
C These common blocks contain variables describing the state of
C the graphics system for various user-written subroutines which
C use the GL subroutines, such as CURVE and CURVE3D.

        LOGICAL WISOPEN

        COMMON /CVSTATE/ WISOPEN
        
        INTEGER  WX1, WX2, WY1, WY2
        PARAMETER (WX1=500, WX2=1200, WY1=300, WY2=1000)

C Definitions for GL/VOGL:

        INCLUDE 'fvogl.h'               ! for VOGL        
        INCLUDE 'fvodevice.h'           ! for VOGL

C Use these instead if you are using real GL on an SGI instead of VOGL

c$$$        INCLUDE 'fgl.h'                 ! for GL
c$$$        INCLUDE 'fdevice.h'             ! for GL
