Fixed a regression bug, which was made during the porting ofversion_1.37.1

discover_horizontal_shells() fron Perl to C++, where

Improved constness of the debug methods
    void export_region_slices_to_svg(const char *path) const;
    void export_region_fill_surfaces_to_svg(const char *path) const;
