Icons
- When an application uses icons, an icon theme should be available in XDG_DATA_DIRS. The package for the default, icon-less hicolor-icon-theme contains a setup hook that will pick up icon themes from buildInputs and pass it to our wrapper. Unfortunately, relying on that would mean every user has to download the theme included in the package expression no matter their preference. For that reason, we leave the installation of icon theme on the user. If you use one of the desktop environments, you probably already have an icon theme installed.
