		213	operating system command) is processed. Cursor position and other state
		214	information is up-to-date when this happens. For interoperability, the

		225	Called whenever text is about to be output, with the text as argument. You
		226	can filter/change and output the text yourself by returning a true value
		227	and calling C<< $term->scr_add_lines >> yourself. Please note that this

		230
		231	=item on_line_update $term, $row
		232
		233	Called whenever a line was updated or changed. Can be used to filter
		234	screen output (e.g. underline urls or other useless stuff). Only lines
		235	that are being shown will be filtered, and, due to performance reasons,
		236	not always immediately.
		237
		238	The row number is always the topmost row of the line if the line spans
		239	multiple rows.
		240
		241	Please note that, if you change the line, then the hook might get called
		242	later with the already-modified line (e.g. if unrelated parts change), so
