[Joshua Leung]

Revision: 11385
          http://projects.blender.org/plugins/scmsvn/viewcvs.php?view=rev&root=bf-blender&revision=11385

Log Message:
-----------
Object Transform:

If object has a parent, and constraints should not be inversed for transform, then constraints are now disabled like tracking is.
