opacity does not work that way; opacity is always composited along with

Okay, I see : setting the opacity down the tree makes a top-limit on all
future opacities, but they can go downwards.
I'd like to be able to 'dim' everything in a given Group, and then
'focus/saturate/pick-out' a particular node. It does not have to involve
opacity, I'd rather it were a kind of 'wash-out' effect, like a colour tint.
