2007-Oct-17 UPDATE Jean-Pierre Charras <jean-pierre.charras@inpg.fr>
================================================================================
+ pcbnew:
Removed enhancements in connectivity computation because
rastnest computation does not work (errors) with short track segments
(lenght < width) . This is not a bug, but an algorithm problem, so
I must work on algos.
