[GTK] Shading of the entire window when the focus is switched to another application

[RomanAverin]

If I use split panels, when I switch focus to another application, the entire ghostty window is shaded, but only the window titlebar and the inactive split panel are shaded. If you don't use split, everything works fine.

This is because the global "shading" is only applied to GTK/libadwaita widgets and we don't actually write any code for it — the toolkits do that for us. It's debatable whether we should extend the shading to the rest of the terminal, though. For context, neither of the two other major GTK4 terminals, Ptyxis and GNOME Console, do this.

What config options give you this?

This is a feature I've been looking for - entire window (not a split section) to change colour / shading /transparency on focus / unfocus,

SO, Is there a combination of config options to allow the entire window, on focus / unfocus to be either
shaded / unshaded
or transparent?

I used to rely on this with urxvt & have looked for this in other terminals (I moved away from urxvt to get cleaner looking fonts at small font sizes).

There isn't a config option because shading is applied by GTK and out of our control. My question is that if we should even allow people to do so, given that this is not established behavior for other GTK-based terminals.
