/** HitTestPrimitive2D class
This primitive is used to represent geometry for non-visible objects,
e.g. a PresObj's outline. To still be able to use primitives for HitTest
functionality, the 2d decompositions will produce an as much as possible
simplified line geometry encapsulated in this primtive when there is no
line geometry. In a further enchanced version this may change to 'if neither
filled nor lines' creation criteria. The whole primitive decomposes to nothing,
so no one not knowing it will be influenced. Only helper processors for hit test
(and maybe BoundRect extractors) will use it and it's children subcontent.
