GSS Computer Graphics Interface (GSS*CGI)

        Entry:
          DS:DX = Pointer to block of 5 array pointers
        Return:
          CF = 0
            AX = return code
          CF = 1
            AX = error code

        Note: INT 59h is the means by which GSS*CGI language bindings
              communicate with GSS*CGI device drivers and the GSS*CGI
              device driver controller. Also used by the IBM Graphic
              Development Toolkit.
