too bad the discussion does not explain why you need the ppi, or
what it would be used for. There are many uses for ppi that
people think are proper, but fall apart very quickly in practice.

Seems like this would call for lots of standard things:
- creating a representation of an output
- signalling which output a window is showing on, and updating it
dynamically as the window moves and outputs are plugged in and out
- delivering output ppi every time it changes permanently (video
Assuming you had all that, what will you then do, when your window
is shown on more than one output with differing ppis?
All this assuming the issues Jasper mentioned were already solved.
Or, how would a DE know which ppi it needs to advertise at a time?
Should there only one ppi per window at a time?
