== Copy Scale Constraint - Offset ==

Now the Copy Scale Constraint also has the Offset functionality that Copy Loc/Rot have. 


== Copy Rotation Constraint == 

Also, fixed the tooltip for the CopyRot Offset button.

Note: when working with pose-bones, and using offset, setting both owner+target spaces to pose-space should cancel any unwanted rotations visible.
