//   - For a horizontal hairline (Object with height 0), the generated data is +/-100, i.e.
//     a vertical area of 200 logical units is sensitive.
//   - For a polygon, a rectangular of the size (200,200) is generated and a
//     touch test between Poly and this Rect is processed.
//   - Obects which respond SdrObject::HasEdit()==TRUE ( e.g. a text frame ),
//     are specially treated: An additional sensitive area with a width of
//     2*Tol (200 units for this example) is created around the object.
//     When an object is directly hit, the Edit method is called.
//     In opposite, a hit in the surrounding sensitive area enables Dragging.
