|
|
|
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.
