Actually, if you leave the visible border intact by not making the
PhotoOverlay completely transparent (using a transparent PNG image so
you can still look through it), that border shows the exact FOV of
whatever you're trying to replicate quite nicely.

I tried it myself recently and while the <Update> worked, I had to 're-
enter' the PhotoOverlay to see changes. Sorry, I'm out of ideas now.
At most someone might find an obscure workaround.
I'll put it on the feature requests page (by the looks of it it will
be #105):
