CIRCLE draws a circle with center coordinates x,y and radius r. Additional
starting and ending angles w1 and w2 can be specified to draw a circular arc.
Similarly, PCIRCLE draws a filled circle or filled circular arc.

ELLIPSE draws an ellipse with the center coordinates x,y and horizontal radius
rx and vertical radius ry. Optional starting and ending angles w1 and w2 can be
specified to draw an elliptical arc. Similarly, PELLIPSE draws a filled ellipse
or a filled elliptical arc. The angles should be specified in 1/10 degress
(0-3600) and are measured in an anti-clockwise direction with zero pointing to
the right. See notation below.
