Please don't mix everything and read carefully what I said.

Pressing "Print screen" IS the event that proves the physical user of 
the computer wants it, not another app. No need for a popup.
The pop up is only useful if no user intent is not known by the 
compositor. That is to say, when an app that didn't get run in response 
to a print-screen hot key tries to get a screenshot, it shouldn't be 
allowed without the user's consent.

What Sebastian wants is simply to have a pool of trusted apps who can 
access restricted interfaces. I find this insufficient for the reasons I 
listed before (what happens if you install an app that allows taking 
screenshots and save them to a file automatically? without any input 
from the user? Well, you just lost the confidentiality of your display, 
too bad...).

Cheers,
Martin
