// This primitive is used to represent geometry for non-visible objects,

// primitives for HitTest functionality, the 3d decompositions produce
// an as much as possible simplified fill geometry encapsulated in this
// primtive when there is no fill geometry. Currently, the 3d hit test
// uses only areas, so maybe in a further enchanced version this will 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.
