Here's an update.  The UV seams are being successfully split in the simplest of test cases, in which target texverts are split when they correspond directly to the source texvert on the seam.  Other seam cases are still bad, and the UV process currently leaks a lot of RAM.  Obviously there's a way yet to go with this, so I think I'm going to move on to the multi-actor and multi-morph transfers.

This does add a new version of shape transfer, which transfers the actual current morphed shape of the source to the target.  This sort of transfer seems to suffer less from the "lumpy" morphs effect seen in straight delta transfer.  A function to trim a morph, using the selection and exclusion methods used elsewhere in the script, is also added, as well as some changes and refinements to the smoothing functions and morph unique name protections.

I thought we could upload .txt files now, but the upload fails.  What gives?
