		213
		214	=item on_osc_seq $term, $string
		215
		216	Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
		217	operating system command) is processed. Cursor position and other state
		218	information is up-to-date when this happens. For interoperability, the
		219	string should start with the extension name and a colon, to distinguish
		220	it from commands for other extensions, and this might be enforced in the
		221	future.
		222
		223	Be careful not ever to trust (in a security sense) the data you receive,
		224	as its source can not easily be controleld (e-mail content, messages from
		225	other users on the same system etc.).
		226
		227	=item on_add_lines $term, $string
		228
		229	Called whenever text is about to be output, with the text as argument. You
		230	can filter/change and output the text yourself by returning a true value
		231	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		232	might be very slow, however, as your hook is called for B<all> text being
		233	output.
		234
		235	=item on_line_update $term, $row
		236
		237	Called whenever a line was updated or changed. Can be used to filter
		238	screen output (e.g. underline urls or other useless stuff). Only lines
		239	that are being shown will be filtered, and, due to performance reasons,
		240	not always immediately.
		241
		242	The row number is always the topmost row of the line if the line spans
		243	multiple rows.
		244
		245	Please note that, if you change the line, then the hook might get called
		246	later with the already-modified line (e.g. if unrelated parts change), so
		247	you cannot just toggle rendition bits, but only set them.
