public interface Shape
This interface represents an abstract shape. The shape is described by
a PathIterator, and has callbacks for determining bounding box,
where points and rectangles lie in relation to the shape, and tracing
the trajectory.
A point is inside if it is completely inside, or on the boundary and
adjacent points in the increasing x or y direction are completely inside.
Unclosed shapes are considered as implicitly closed when performing
contains or intersects.

Rectangle getBounds()
Rectange that bounds the shape. There is no
guarantee that this is the minimum bounding box, particularly if
the shape overflows the finite integer range of a bound. Generally,
getBounds2D returns a tighter bound.

transform - an optional transform to apply to the
iterator (null permitted).
PathIterator getPathIterator(AffineTransform transform,
double flatness)
If the optional transform is provided, the iterator is transformed accordingly. Each call returns a new object, independent from others in use. It is recommended, but not required, that the Shape isolate iterations from future changes to the boundary, and document this fact.

iterator (null permitted).flatness - the maximum distance for deviation from the real boundary
