Definition

The concept PMPAutorefinementVisitor defines the requirements for the visitor used in CGAL::Polygon_mesh_processing::autorefine_triangle_soup() to track the creation of new triangles.

Functions called only if at least one intersection has been found
void	number_of_output_triangles (std::size_t nbt)
	called when the final number of output triangles is known, `nbt` being the total number of triangles in the output.

void	verbatim_triangle_copy (std::size_t tgt_id, std::size_t src_id)
	called for triangle with no intersection, `tgt_id` is the position in the triangle container after calling `autorefine_triangle_soup()`, while `src_id` was its position before calling the function.

void	new_subtriangle (std::size_t tgt_id, std::size_t src_id)
	called for each subtriangle created from a triangle with intersection, `tgt_id` is the position in the triangle container after calling `autorefine_triangle_soup()` of the subtriangle, while `src_id` was the position of the original support triangle before calling the function.

void	delete_triangle (std::size_t src_id)
	called for each input triangle absent in the output because it was degenerate. `src_id` is the position of that triangle in the input range. Additionally, if `apply_iterative_snap_rounding()` is set to `true`, some extra triangles might become degenerate and will be absent in the output. Those triangles are also reported by this function.
