// This primitive is used to represent geometry for non-visible objects,
30
// e.g. a PresObj's outline. To still be able to use primitives for HitTest
31
// functionality, the 2d decompositions will produce an as much as possible
32
// simplified line geometry encapsulated in this primitive when there is no
33
// line geometry. In a further enhanced version this may change to 'if neither
34
// filled nor lines' creation criteria. The whole primitive decomposes to nothing,
35
// so no one not knowing it will be influenced. Only helper processors for hit test
36
// (and maybe BoundRect extractors) will use it and its children subcontent.
