-# This script transfer the shape from an object (base mesh without
-# modifiers) to another object with modifiers (i.e. posed Armature).
-# Only two objects must be selected.
-# The first selected object will be added to the second selected
-# object as a new shape key.
-#
-# Original 2.4x script by ? (brecht?)
-# Unpose-function reused from a script by Tal Trachtman in 2007 http://www.apexbow.com/randd.html
-# Converted to Blender 2.5 by Ivo Grigull
-#
-# Limitations:
-# Target mesh may not have any transformation at object level, it will be set to zero.
-# Fast/Armature method does not work with Bone envelopes or dual quaternions, both settings will be disabled in the modifier
