The recent refactoring work to move zones from CPolyLine to
SHAPE_POLY_SET resulted in a reduction in pcbnew's python
capabilities. This change exposed SHAPE_POLY_SET to restore
that functionality (albeit with slightly different method names)
Removes the need of using the legacy code in polygon/PolyLine.{h,cpp},
refactoring all CPolyLine instances with SHAPE_POLY_SET instances.
The remaining legacy methods have been ported to SHAPE_POLY_SET;
mainly: Chamfer, Fillet, {,Un}Hatch.
The iteration over the polygon vertices have been simplified using the
family of ITERATOR classes.
In polygon calculations (combining polygons, fracture) the mode of calculation (fast or strictly simple polygon option) as no more a default value, because choosing the best mode is better to optimize the calculation time.
In 3D viewer, this option can take a *very long* calculation time (minutes instead of seconds, or hangs) and they are now using aFastMode = true to do polygon calculations, especially for zones inside zones belong to the same net but having different priority (which creates weak polygons).
aFastMode = false is the default for other calculations (zone filling) as before.
