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.
