		140	=head2 Extension Objects
		141
		142	Very perl extension is a perl class. A separate perl object is created
		143	for each terminal and each extension and passed as the first parameter to
		144	hooks. So extensions can use their C<$self> object without having to think
		145	about other extensions, with the exception of methods and members that
		146	begin with an underscore character C<_>: these are reserved for internal
		147	use.
		148
		149	Although it isn't a C<urxvt::term> object, you can call all methods of the
		150	C<urxvt::term> class on this object.
		151
		152	It has the following methods and data members:

		160
		161	=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
		162
		163	Dynamically enable the given hooks (named without the C<on_> prefix) for
		164	this extension, replacing any previous hook. This is useful when you want
		165	to overwrite time-critical hooks only temporarily.

167	Called whenever the program(s) running in the urxvt window send output.	252	Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
		253	operating system command) is processed. Cursor position and other state
		254	information is up-to-date when this happens. For interoperability, the
		255	string should start with the extension name and a colon, to distinguish
		256	it from commands for other extensions, and this might be enforced in the
		257	future.
		258
		259	Be careful not ever to trust (in a security sense) the data you receive,
		260	as its source can not easily be controleld (e-mail content, messages from
		261	other users on the same system etc.).
		262
		263	=item on_add_lines $term, $string
		264
		265	Called whenever text is about to be output, with the text as argument. You
		266	can filter/change and output the text yourself by returning a true value
		267	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		268	might be very slow, however, as your hook is called for B<all> text being
		269	output.
		270
		271	=item on_tt_write $term, $octets
		272
		273	Called whenever some data is written to the tty/pty and can be used to
		274	suppress or filter tty input.
		275
		276	=item on_line_update $term, $row
		277
		278	Called whenever a line was updated or changed. Can be used to filter
		279	screen output (e.g. underline urls or other useless stuff). Only lines
		280	that are being shown will be filtered, and, due to performance reasons,
		281	not always immediately.
		282
		283	The row number is always the topmost row of the line if the line spans
		284	multiple rows.
		285
		286	Please note that, if you change the line, then the hook might get called
		287	later with the already-modified line (e.g. if unrelated parts change), so
		288	you cannot just toggle rendition bits, but only set them.
