		210
		211	Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
		212	operating system command) is processed. Cursor position and other state
		213	information is up-to-date when this happens. For interoperability, the

		222	=item on_add_lines $term, $string
		223
		224	Called whenever text is about to be output, with the text as argument. You
		225	can filter/change and output the text yourself by returning a true value
		226	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		227	might be very slow, however, as your hook is called for B<all> text being
		228	output.
		229
		230	=item on_line_update $term, $row
		231
		232	Called whenever a line was updated or changed. Can be used to filter
		233	screen output (e.g. underline urls or other useless stuff). Only lines
		234	that are being shown will be filtered, and, due to performance reasons,
		235	not always immediately.
		236
		237	The row number is always the topmost row of the line if the line spans
		238	multiple rows.
		239
		240	Please note that, if you change the line, then the hook might get called
		241	later with the already-modified line (e.g. if unrelated parts change), so
		242	you cannot just toggle rendition bits, but only set them.
