**CIGAL Reference Manual, Chapter 6 (RealTime): r_point**
===== r_point -- Set the intensity value of a single screen pixel =====
**usage: r_point  opflg eflag ltime Point Intens [Scalevec]**

The intensity of the screen pixel at position POINT is set to INTENS.
POINT is a short integer array of the form { X, Y }.

If SCALEVEC is specified it is assumed to be a short integer array of 6
elements indicating how to scale the Y value before plotting. The contents
of SCALEVEC are:
          { yoff0   ymult   ydiv   yoff1   ymin   ymax }

The resulting Y value is:
          Ynew = (Yold - yoff0) * ymult / ydiv + yoff1

and if ymax is greater than ymin, then Ynew is clipped if necessary to stay
within those bounds.
