**CIGAL Reference Manual, Chapter 6 (RealTime): r_efill**
===== r_efill -- Draw a filled ellipse (or circle) =====
**usage: r_efill  opflg eflag ltime Intensity Box**

R_EFILL is a REALTIME operator. It draws a filled ellipse on the screen.  The
color is determined by the INTENSITY value, which will be mapped through the
active color lookup table to produce a color. The size and position of the
ellipse are determined by the BOX argument, which is a short integer array
specifying a screen region (4 values: left, top, right, bottom); the ellipse
is drawn with its horizontal axis determined by the width and its vertical
axis determined by the height of BOX.
