		107	Argument names also often indicate the type of a parameter. Here are
		108	some hints on what they mean:
		109
		110	$text
		111	Rxvt-unicodes special way of encoding text, where one "unicode"
		112	character always represents one screen cell. See ROW_t for a
		113	discussion of this format.
		114
		115	$string
		116	A perl text string, with an emphasis on text. It can store all
		117	unicode characters and is to be distinguished with text encoded in a
		118	specific encoding (often locale-specific) and binary data.
		119
		120	$octets
		121	Either binary data or - more common - a text string encoded in a
		122	locale-specific way.
		123
		124	Extension Objects
		125	Very perl extension is a perl class. A separate perl object is created
		126	for each terminal and each extension and passed as the first parameter
		127	to hooks. So extensions can use their $self object without having to
		128	think about other extensions, with the exception of methods and members
		129	that begin with an underscore character "_": these are reserved for
		130	internal use.
		131
		132	Although it isn't a "urxvt::term" object, you can call all methods of
		133	the "urxvt::term" class on this object.
		134
		135	It has the following methods and data members:
		136
		137	$urxvt_term = $self->{term}
		138	Returns the "urxvt::term" object associated with this instance of
		139	the extension. This member must not be changed in any way.
		140
		141	$self->enable ($hook_name => $cb, [$hook_name => $cb..])
		142	Dynamically enable the given hooks (named without the "on_" prefix)
		143	for this extension, replacing any previous hook. This is useful when
		144	you want to overwrite time-critical hooks only temporarily.
		145
		146	$self->disable ($hook_name[, $hook_name..])
		147	Dynamically disable the given hooks.
		148

		233	on_add_lines $term, $string
		234	Called whenever text is about to be output, with the text as
		235	argument. You can filter/change and output the text yourself by
		236	returning a true value and calling "$term->scr_add_lines" yourself.
		237	Please note that this might be very slow, however, as your hook is

		243
		244	on_line_update $term, $row
		245	Called whenever a line was updated or changed. Can be used to filter

		248	reasons, not always immediately.
		249
		250	The row number is always the topmost row of the line if the line
		251	spans multiple rows.
		252
		253	Please note that, if you change the line, then the hook might get
		254	called later with the already-modified line (e.g. if unrelated parts
		255	change), so you cannot just toggle rendition bits, but only set
		256	them.
