* This is a simple utility designed to extract the paths from an SKP file and then isolate a single
* one of them via bisect. Use the 'x' and 'X' keys to guide a binary search:
* 'x': Throw out half the paths.
* 'X': Toggle which half gets tossed and which half is kept.
* 'Z': Back up one level.
* 'D': Dump the path.
