Note that if you run the script using a different figure, you really ought to create a fresh runtime containing another set of the copies of poses you which to convert from.

Let's say you've already converted the poses using SydneyG2.

Now, I want to convert the poses for Michael4, say.  At this point, I don't know how truly Universal these conversions are.  So to be sure, I made a second copy runtime with the physical poses I want converted.  And then I ran the script on the poses in that runtime.

When I am satisfied that the conversions are sufficiently Universal across figure types ( Humanoid Bipeds ), I shall delete one or the other of these runtimes.
