cae-tools/cameo/cameo.c
Werner Almesberger 17afa3e2bb Accept multiple paths and distinguish between inner paths and the outer path.
- 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.
