## Icon retrieval

When an icon is retrieved for a mimetype, if the full mimetype cannot be found, the search will fallback to looking for the part before the slash. Given a file with the mimetype ‘image/my-custom-image’, if no icon exists for the full mimetype, the icon for ‘image’ will be used instead. This allows specialised mimetypes to fallback to generic icons when the relevant icons are unavailable.
