- */
-
-/**
- * JavaScript porting of Markus Kuhn's wcwidth() implementation
- *
- * The following explanation comes from the original C implementation:
- *
- * This is an implementation of wcwidth() and wcswidth() (defined in
- * IEEE Std 1002.1-2001) for Unicode.
- *
- * http://www.opengroup.org/onlinepubs/007904975/functions/wcwidth.html
- * http://www.opengroup.org/onlinepubs/007904975/functions/wcswidth.html
- *
- * In fixed-width output devices, Latin characters all occupy a single
- * "cell" position of equal width, whereas ideographic CJK characters
- * occupy two such cells. Interoperability between terminal-line
- * applications and (teletype-style) character terminals using the
- * UTF-8 encoding requires agreement on which character should advance
- * the cursor by how many cell positions. No established formal
- * standards exist at present on which Unicode character shall occupy
- * how many cell positions on character terminals. These routines are
- * a first attempt of defining such behavior based on simple rules
- * applied to data provided by the Unicode Consortium.
- *
- * For some graphical characters, the Unicode standard explicitly
- * defines a character-cell width via the definition of the East Asian
- * FullWidth (F), Wide (W), Half-width (H), and Narrow (Na) classes.
- * In all these cases, there is no ambiguity about which width a
- * terminal shall use. For characters in the East Asian Ambiguous (A)
- * class, the width choice depends purely on a preference of backward
- * compatibility with either historic CJK or Western practice.
- * Choosing single-width for these characters is easy to justify as
- * the appropriate long-term solution, as the CJK practice of
- * displaying these characters as double-width comes from historic
- * implementation simplicity (8-bit encoded characters were displayed
- * single-width and 16-bit ones double-width, even for Greek,
- * Cyrillic, etc.) and not any typographic considerations.
- *
- * Much less clear is the choice of width for the Not East Asian
- * (Neutral) class. Existing practice does not dictate a width for any
- * of these characters. It would nevertheless make sense
- * typographically to allocate two character cells to characters such
- * as for instance EM SPACE or VOLUME INTEGRAL, which cannot be
- * represented adequately with a single-width glyph. The following
- * routines at present merely assign a single-cell width to all
- * neutral characters, in the interest of simplicity. This is not
- * entirely satisfactory and should be reconsidered before
- * establishing a formal standard in lib.wc area. At the moment, the
- * decision which Not East Asian (Neutral) characters should be
- * represented by double-width glyphs cannot yet be answered by
- * applying a simple rule from the Unicode database content. Setting
- * up a proper standard for the behavior of UTF-8 character terminals
- * will require a careful analysis not only of each Unicode character,
- * but also of each presentation form, something the author of these
- * routines has avoided to do so far.

- * @fileoverview This class represents a single terminal screen full of text.
- *
- * It maintains the current cursor position and has basic methods for text
- * insert and overwrite, and adding or removing rows from the screen.
- *
- * This class has no knowledge of the scrollback buffer.
- *
- * The number of rows on the screen is determined only by the number of rows
- * that the caller inserts into the screen.  If a caller wants to ensure a
- * constant number of rows on the screen, it's their responsibility to remove a
- * row for each row inserted.
- *
- * The screen width, in contrast, is enforced locally.
- *
- *
- * In practice...
- * - The hterm.Terminal class holds two hterm.Screen instances.  One for the
- * primary screen and one for the alternate screen.
- *
- * - The html.Screen class only cares that rows are HTMLElements.  In the
- * larger context of hterm, however, the rows happen to be displayed by an
- * hterm.ScrollPort and have to follow a few rules as a result.  Each
- * row must be rooted by the custom HTML tag 'x-row', and each must have a
- * rowIndex property that corresponds to the index of the row in the context
- * of the scrollback buffer.  These invariants are enforced by hterm.Terminal
- * because that is the class using the hterm.Screen in the context of an
- * hterm.ScrollPort.
