 * @brief The AbstractPartEllipse class
 * This is the base class for all ellipse based item like ellipse, circle, arc.
 * This class only provide common method for edit the ellipse like rect that contain the ellipse.
 * All coordinates is in item coordinate, except pos(), center(), centerX() and centerY()
 * which are in parent coordinate (or scene if no parent).
 *
 * In several points, this class is a copy of QGraphicsEllipseItem with some change,
 * (the use of Q_PROPERTY) to be easily used with Element editor.
