ps_circle — Draws a circle
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.
