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:
