		203
		204	=item on_osc_seq $term, $string
		205
		206	Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
		207	operating system command) is processed. Cursor position and other state
		208	information is up-to-date when this happens. For interoperability, the

		210	it from commands for other extensions, and this might be enforced in the

		213	Be careful not ever to trust (in a security sense) the data you receive,

		216
		217	=item on_add_lines $term, $string
		218
		219	Called whenever text is about to be output, with the text as argument. You
		220	can filter/change and output the text yourself by returning a true value
		221	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		222	might be very slow, however, as your hook is called for B<all> text being
		223	output.
		224
		225	=item on_line_update $term, $row
		226
		227	Called whenever a line was updated or changed. Can be used to filter
		228	screen output (e.g. underline urls or other useless stuff). Only lines
		229	that are being shown will be filtered, and, due to performance reasons,
		230	not always immediately.
		231
		232	The row number is always the topmost row of the line if the line spans
		233	multiple rows.
		234
		235	Please note that, if you change the line, then the hook might get called
		236	later with the already-modified line (e.g. if unrelated parts change), so
		237	you cannot just toggle rendition bits, but only set them.
