Actually it would make sense for a subpicture source filter
if we're able to define coordinates in the display space /
video area too, but I'm not sure whether it's currently
possible or not, and how the event should be handled in that
I don't follow what compositing has to do here though.
Coordinates has to match in most compositors system
