As a side note the problem with both alternate approaches that we
showed (which do the same thing) is that the snap 3d function does not
take a format argument, and only returns the values for the root
format, so the result is only correct for that format. Maybe we should
put in a request for the function to take in a format/resolution argument?

yeh thanks for that again: it works just fine. it does choke a wee
bit in the gui every now and then but it totally does what I was
aiming for.
I also liked Jose's approach so thanks for that too - very creative!
I guess I'll just wait for new releases then and hope it gets
incorporated as a one stop solution? question mark
cheers everyone
that's what I did to work around this. Fairly rough and
untested though:

I'm wondering if anyone has used the snap3d.project points
successfully to achieve this (I mean, if it's actually
stable and usable). For starters it seems like it only
takes the root format of the script, but it might be
possible to cheat it through the win_scale u v. Anyway,
just curious, an example setup:
