While working with Graphics.draw.Ellipse(), I believe I discovered an error in the documentation. The four parameters (x, y, width, height) are stated to be the x/y coordinates of the upper-left corner of the framing rectangle of the ellipse, along with the width and height of the ellipse. As currently implemented, x and y are actually the coordinates of the CENTER of the ellipse, width is the horizontal RADIUS (one/half the total width), and height is the vertical RADIUS (one-half the total height). The function works fine otherwise. - prof
