This script creates "raw" copies of deformed meshes.

Usage:

Select the mesh(es) and run this script.  A fixed copy of each selected mesh
will be created, with the word "_deformed" appended to its name. If an object with
the same name already exists, it appends a number at the end as Blender itself does.

Meshes in Blender can be deformed by armatures, lattices, curve objects and subdivision, but this will only change its appearance on screen and rendered
images -- the actual mesh data is still simpler, with vertices in an original
"rest" position and less vertices than the subdivided version.

Use this script if you want a "real" version of the deformed mesh, so you can
directly manipulate or export its data.
