Feature request: blur whitelist option

[Rivet92]

Would be nice to have an option to define which windows have blur transparency instead of having to blacklist everything else.

[M4he]

Should already be possible by negating the conditional like this:

blur-background-exclude = [
    "!(class_g = 'Tilix' || class_g = 'Tint2')"
];

This effectively whitelists the window classes Tilix and Tint2 for blurring.
