- The routines above are functionally the same. However, the type
- declarations for the coordinates differ.

- _x expects the x coordinate of the center of the circle specified
- in world coordinates.
-
- _y expects the y coordinate of the center of the circle specified
- in world coordinates.
-
- _r_a_d_i_u_s expects the length of the radius of the circle.

- cccciiiirrrrcccc draws an unfilled circle in the _x-_y plane with _z assumed to be zero.
- To create a circle that does not lie in the _x-_y plane, draw the circle in
- the _x-_y plane, then rotate and/or translate the circle. Note that circles
- rotated outside the 2-D _x-_y plane appear as ellipses.
-
- A circle is drawn as a sequence of line segments, and therefore inherits
- all properties that affect the drawing of lines. These include the
- current color, writemask, line width, stipple pattern, shade model, line
- antialiasing mode, and subpixel mode. The stipple pattern is initialized
- to bit zero of the current linestyle before the circle is drawn, then
- shifted continuously through the segments of the circle.
-
- After cccciiiirrrrcccc executes, the graphics position is undefined.

- When the line width is greater than 1, small notches will appear in
- circles, because of the way wide lines are implemented.
