Looks like I have a real knack for finding these little bugs - even when I don't
know they're there, and I'm doing something completely wrong and pointless  :D

That would be a neat feature!
I checked the docs and didn't see anything like that.
I've written my own bounding-box visualization macro to do that, as well as show
the min/max extent in the debug window ("WHERE'D my object{} go????")
I think I threw in my camera-object-distance based auto-cylinder radius thing to
give a nice consistent look to it as well whether it's 5 units or 50,000 units
from the camera.
Still needs a slight bit of fine-tuning.
