debian: Suggest humanity-icon-theme

[aleasto]

index.theme specifies Inherits=Humanity, so we should at least suggest having humanity-icon-theme installed.

[aleasto]

This opens more questions though:

• Is Yaru still an incomplete theme without falling back to Humanity?

• If so, is it important enough to bump the dependency up to a Recommends or even Depends?

[jbicha]

If we're modifying this repo anyway, my suggestion is to remove the Inherits=Humanity. I'm not a maintainer of this project though.

From the list of names in the spec: https://specifications.freedesktop.org/icon-naming-spec/latest/#names, I've verified that Yaru is missing these icons:

plus all the ISO-3166 flag-aa icons.

Many of those have -symbolic variants, but only -symbolic icons can fallback to the regular ones and not the other way around.

So technically, it is not a complete theme. How much that matters however, I don't know.

By the same test, Humanity is also not a complete theme. And the following icons are missing from both Yaru and Humanity:

plus all the ISO-3166 flag-aa icons again.

But Humanity inherits from Adwaita, so finally these are the only missing icons when following the whole dependency chain Yaru->Humanity->Adwaita->AdwaitaLegacy:

accessories-screenshot-tool, emblem-synchronized, and all the ISO-3166 flags.

[jbicha]

Yaru provides far more icons than Adwaita does, but there are a lot of GNOME distros that only ship the Adwaita icon theme. Therefore, I don't think missing "standard" icons matter these days.
