Constructor Summary
`Circle()` Creates an uninitialized circle.
`Circle(Vector2f center, float radius)` Creates a circle with the supplied center and radius.

Method Summary
`boolean`	`contains(Vector2f pt)` Checks whether the circle contains the specified point.
`ShapeConfig`	`createConfig()` Creates a config corresponding to this shape.
`void`	`draw(boolean outline)` Draws this shape in immediate mode.
`Shape`	`expand(float amount, Shape result)` Expands this shape, placing the result in the provided object if possible.
`Vector2f`	`getCenter()` Returns a reference to the center of the circle.
`Vector2f`	`getCenter(Vector2f result)` Retrieves the center of the shape and places it in the supplied vector.
`boolean`	`getIntersection(Ray2D ray, Vector2f result)` Finds the intersection of a ray with this shape and places it in the supplied vector (if it exists).
`Shape.IntersectionType`	`getIntersectionType(Rect rect)` Checks whether the intersector intersects the specified rect.
`void`	`getNearestPoint(Vector2f point, Vector2f result)` Fins the nearest point of this element to the supplied point and places it in the supplied vector.
