-"""
-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
