		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

		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
