libmath-clipper-perl binary package in Ubuntu Focal arm64

 Math::Clipper is a C++ (and Delphi) library that implements polygon
 clipping. A Polygon is represented by a reference to an array of 2D
 points. A Point is, in turn, represented by a reference to an array
 containing two numbers: The X and Y coordinates.
 .
 Clipper 4.x works with polygons with integer coordinates. Data in
 floating point format will need to be scaled appropriately to be
 converted to the available integer range before polygons are added to a
 clipper object. (Scaling utilities are provided.)
