DrawEllipse -- Draw an ellipse centered at cx,cy with vertical
and horizontal radii of a,b respectively.
DrawEllipse( rp, cx, cy, a, b )
a1 d0 d1 d2 d3
void DrawEllipse( struct RastPort *, SHORT, SHORT, SHORT, SHORT);
Creates an elliptical outline within the rectangular region
specified by the parameters, using the current foreground pen color.
rp - pointer to the RastPort into which the ellipse will be drawn.
cx - x coordinate of the centerpoint relative to the rastport.
cy - y coordinate of the centerpoint relative to the rastport.
a - the horizontal radius of the ellipse (note: a must be > 0)
b - the vertical radius of the ellipse (note: b must be > 0)
this routine does not clip the ellipse to a non-layered rastport.
