+Description: use HighContrast icons for HighContrast theme
+ Adwaita is missing some icons used e.g. in the System Settings.
+ Replacing the icon set for HighContrast theme results in no
+ missing icons in the settings app. However, some icons missing
+ from the HighContrast set are replaced by their Adwaita counterparts.
