		583

		587
		588	Returns the negative row number of the topmost line. Minimum value is

		590	this many lines into the scrollback buffer.
		591
		592	=item $term->want_refresh
		593
		594	Requests a screen refresh. At the next opportunity, rxvt-unicode will

		599
		600	=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		601
		602	Returns the text of the entire row with number C<$row_number>. Row C<0>
		603	is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
		604	terminal line. The scrollback buffer starts at line C<-1> and extends to
		605	line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line
		606	is requested.
		607
		608	If C<$new_text> is specified, it will replace characters in the current
		609	line, starting at column C<$start_col> (default C<0>), which is useful
		610	to replace only parts of a line. The font index in the rendition will
		611	automatically be updated.
		612
		613	C<$text> is in a special encoding: tabs and wide characters that use more
		614	than one cell when displayed are padded with urxvt::NOCHAR characters
		615	(C<chr 65535>). Characters with combining characters and other characters
		616	that do not fit into the normal tetx encoding will be replaced with
		617	characters in the private use area.
		618
		619	You have to obey this encoding when changing text. The advantage is
		620	that C<substr> and similar functions work on screen cells and not on
		621	characters.
		622
		623	The methods C<< $term->special_encode >> and C<< $term->special_decode >>
		624	can be used to convert normal strings into this encoding and vice versa.
		625
		626	=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		627
		628	Like C<< $term->ROW_t >>, but returns an arrayref with rendition
		629	bitsets. Rendition bitsets contain information about colour, font, font
		630	styles and similar information. See also C<< $term->ROW_t >>.
		631
		632	When setting rendition, the font mask will be ignored.
		633
		634	See the section on RENDITION, above.
		635
		636	=item $length = $term->ROW_l ($row_number[, $new_length])
		637
		638	Returns the number of screen cells that are in use ("the line
		639	length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the
		640	line is joined with the following one.
		641
		642	=item $bool = $term->is_longer ($row_number)
		643
		644	Returns true if the row is part of a multiple-row logical "line" (i.e.
		645	joined with the following row), which means all characters are in use
		646	and it is continued on the next row (and possibly a continuation of the
		647	previous row(s)).
		648
		649	=item $line = $term->line ($row_number)
		650
		651	Create and return a new C<urxvt::line> object that stores information
		652	about the logical line that row C<$row_number> is part of. It supports the
		653	following methods:
		654
		655	=over 4
		656
		657	=item $text = $line->t
		658
		659	Returns the full text of the line, similar to C<ROW_t>

		662
		663	Returns the full rendition array of the line, similar to C<ROW_r>
		664
		665	=item $length = $line->l
		666
		667	Returns the length of the line in cells, similar to C<ROW_l>.
