		504	this many lines into the scrollback buffer.
		505
		506	=item $term->want_refresh
		507
		508	Requests a screen refresh. At the next opportunity, rxvt-unicode will

		511
		512	Used after changing terminal contents to display them.
		513
		514	=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		515
		516	Returns the text of the entire row with number C<$row_number>. Row C<0>
		517	is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
		518	terminal line. The scrollback buffer starts at line C<-1> and extends to
		519	line C<< -$term->nsaved >>.
		520
		521	If C<$new_text> is specified, it will replace characters in the current
		522	line, starting at column C<$start_col> (default C<0>), which is useful
		523	to replace only parts of a line. The font index in the rendition will
		524	automatically be updated.
		525
		526	C<$text> is in a special encoding: tabs and wide characters that use more
		527	than one cell when displayed are padded with urxvt::NOCHAR characters
		528	(C<chr 65535>). Characters with combining characters and other characters
		529	that do not fit into the normal tetx encoding will be replaced with
		530	characters in the private use area.
		531
		532	You have to obey this encoding when changing text. The advantage is
		533	that C<substr> and similar functions work on screen cells and not on
		534	characters.
		535
		536	The methods C<< $term->special_encode >> and C<< $term->special_decode >>
		537	can be used to convert normal strings into this encoding and vice versa.
		538
		539	=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		540
		541	Like C<< $term->ROW_t >>, but returns an arrayref with rendition
		542	bitsets. Rendition bitsets contain information about colour, font, font
		543	styles and similar information. See also C<< $term->ROW_t >>.
		544
		545	When setting rendition, the font mask will be ignored.
		546
		547	See the section on RENDITION, above.
		548
		549	=item $length = $term->ROW_l ($row_number[, $new_length])
		550
		551	Returns the number of screen cells that are in use ("the line length"). If
		552	it is C<-1>, then the line is part of a multiple-row logical "line", which
		553	means all characters are in use and it is continued on the next row.
		554
		555	=item $text = $term->special_encode $string
		556
		557	Converts a perl string into the special encoding used by rxvt-unicode,
		558	where one character corresponds to one screen cell. See
		559	C<< $term->ROW_t >> for details.
		560
		561	=item $string = $term->special_decode $text
		562
		563	Converts rxvt-unicodes text reprsentation into a perl string. See
