The parameter $size of the following functions has been deprecated and is not used any more: - file_extension_icon - file_file_icon - file_folder_icon - file_mimetype_icon - mimeinfo_from_type - url_guess_icon That way, the sized icons (xxxxxxx-yyy.png) can be removed and replaced by SVG, to make it easier to keep them updated because once they are replaced, there will only be one single file for each MIME icon.
