- cameo/path.h, cameo/path.c (path_replace): replace a path in a list of paths with a different path - cameo/path.h, cameo/path.c (path_find_leftmost): find the leftmost path in a list of paths - cameo/path.h, cameo/path.c (path_free): move freeing of points to separate function free_points, for sharing with path_replace - cameo/cameo.c (main): move path processing to new function process_paths - cameo/cameo.c (process_paths): treat the leftmost path a outside path and process it last. Treat all others as inside paths.
