Detailed Description

KoParameterShape is the base class for all parametric shapes in flake. Parametric shapes are those whose appearance can be completely defined by a few numerical parameters. Rectangle, ellipse and star are examples of parametric shapes. In flake, these shape parameters can be manipulated visually by means of control points. These control points can be moved with the mouse on the canvas which changes the shapes parameter values and hence the shapes appearance in realtime. KoParameterShape is derived from the KoPathShape class that means by changing the shape parameters, the underlying path is manipulated. A parametric shape can be converted into a path shape by simply calling the setModified method. This makes the path tool know that it can handle the shape like a path shape, so that modifying the single path points is possible.
