/*
* THIS IS WORK IN PROGRESS.
*
* The Python Imaging Library.
*
* "arrow" outline stuff. the contents of this module
* will be merged with the path module and the rest of
* the arrow graphics package, but not before PIL 1.1.
* use at your own risk.
*
* history:
* 99-01-10 fl Added to PIL (experimental)
