C HMIN, HMAX... Horizontal coordinates of the vertical boundaries of
C the plotting area in the plot coordinates.
C The leftmost 1/4 of the screen area is reserved for the
C text output.
C VMIN, VMAX... Vertical coordinates of the horizontal boundaries of
C the plotting area in the plot coordinates.
C WIDTH...Estimated thickness of the plotted line.
C H1A,H1B,H2A,H2B,V2A,V2B,V3A,V3B... Auxiliary variables:
C Coefficients of the linear functions projecting general
C coordinates of a point on a ray to the plot coordinates.
C H1OLD,H2OLD,V2OLD,V3OLD... Auxiliary variables: positions of the
C projections of the last point of a ray to the screen in
C plot coordinates.
