// This primitive is used to represent geometry for non-visible objects,
28
// e.g. a 3D cube without fill attributes. To still be able to use
29
// primitives for HitTest functionality, the 3d decompositions produce
30
// an as much as possible simplified fill geometry encapsulated in this
31
// primitive when there is no fill geometry. Currently, the 3d hit test
32
// uses only areas, so maybe in a further enhanced version this will change
33
// to 'if neither filled nor lines' creation criteria. The whole primitive
34
// decomposes to nothing, so no one not knowing it will be influenced. Only
35
// helper processors for hit test (and maybe BoundRect extractors) will
36
// use it and its children subcontent.
