.. instead of a Primitive2DContainer. The container very frequently contains only a single item, since the decomposition method often sticks only a single top-level node in there, so it turns out to be a net loss overall, memory consumption-wise. Also, if we return a single Primitive2DReference from a BufferedDecomposition, that maximises the sharing of data between the BufferedDecomposition objects at the bottom of the decomposed tree, and objects higher up.

This primitive allows filling a given tools::PolyPolygon with a pattern

defined by a sequence of primitives which are mapped to the unit range.

The pattern is defined using a reference range which defines a rectangular

area relative to the tools::PolyPolygon (in unit coordinates) which is virtually

infinitely repeated.
