Werner Almesberger 54d8549fa2 cameo: detect and adjust handedness
- cameo/path.h, cameo/path.c (offset_point, path_offset): added "left"
  argument to indicate the handedness
- cameo/path.h, cameo/path.c (path_tool_is_left): new function to determine
  which way the path turns
- cameo/cameo.c: auto-detect handedness and instruct path_offset accordingly
