- cameo/cameo.c (process_paths): explain the inside/outside path detection heuristics - cameo/path.h (struct path), cameo/path.c (path_new): added attribute "outside" to explicitly mark paths as outside edges - cameo/path.c (path_from): new function to make a path that takes the attributes of another path - cameo/path.c (path_reverse, path_offset): use path_from instead of path_new - cameo/gnuplot.c (gnuplot_read, gnuplot_do_write): read and write the #%outside hint
