[Bf-blender-cvs] SVN commit: /data/svn/bf-blender [13469] trunk/blender/source/blender/src/ drawarmature.c: Made the line between the start and end of IK-chains for bones display regardless of whether 'Relationship Lines' has been enabled for the view, if the IK-chain was temporarily added for Auto-IK.

Log Message:
-----------
Made the line between the start and end of IK-chains for bones display regardless of whether 'Relationship Lines' has been enabled for the view, if the IK-chain was temporarily added for Auto-IK. This is so that it is possible to see the length of Auto-IK chains.
