bool
ps_circle ( resource psdoc, float x, float y, float radius )
Draws a circle with its middle point at (x,
y). The circle starts and ends at position
(x+radius,
y). If this function is called outside a path it
will start a new path. If it is called within a path it will add the circle
as a subpath. If the last drawing operation does not end in point
(x+radius,
y) then there will be a gap in the path.
