Detailed Description

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.
