And a synthesized name: (((name . "3200x1775 <at> 0,25") (geometry 0 0 3200
1800) (workarea 0 25 3200 1775) (mm-size 599 339) (frames #<frame *scratch*
0x7f7c7009d430>) (source . "NS")))

We could use something like a UUID that's more opaque.

I haven't made either name bi-directional yet to allow specifying it when

Thanks for the help.  Patch attached.
