+A Quick Look at GTK+ CSS ~

+The contents of this subsection apply to GTK+ 3.20 or later which provides
+stable support for GTK+ CSS:
+
+	https://developer.gnome.org/gtk3/stable/theming.html
+
+GTK+ uses CSS for styling and layout of widgets.  In this subsection, we'll
+have a quick look at GTK+ CSS through simple, illustrative examples.
+
+Example 1.  Empty Space Adjustment ~
+
+By default, the toolbar and the tabline of the GTK+ 3 GUI are somewhat larger
+than those of the GTK+ 2 GUI.  Some people may want to make them look similar
+to the GTK+ 2 GUI in size.
+
+To do that, we'll try reducing empty space around icons and labels that looks
+apparently superfluous.
+
+Add the following lines to $XDG_HOME_DIR/gtk-3.0/gtk.css (usually,
+$HOME/.config/gtk-3.0/gtk.css): >
+
+	toolbar button {
+	    margin-top: -2px;
+	    margin-right: 0px;
+	    margin-bottom: -2px;
+	    margin-left: 0px;
+
+	    padding-top: 0px;
+	    padding-right: 0px;
+	    padding-bottom: 0px;
+	    padding-left: 0px
+	}
+
+	notebook tab {
+	    margin-top: -1px;
+	    margin-right: 3px;
+	    margin-bottom: -1px;
+	    margin-left: 3px;
+
+	    padding-top: 0px;
+	    padding-right: 0px;
+	    padding-bottom: 0px;
+	    padding-left: 0px
+	}
+<
+Since it's a CSS, they can be rewritten using shorthand: >
+
+	toolbar button {
+	    margin: -2px 0px;
+	    padding: 0px;
+	}
+
+	notebook tab {
+	    margin: -1px 3px;
+	    padding: 0px
+	}
+<
+Note: You might want to use 'toolbariconsize' to adjust the icon size, too.
+
+Note: Depending on the icon theme and/or the font in use, some extra tweaks
+may be needed for a satisfactory result.
+
+Note: In addition to margin and padding, you can use border.  For details,
+refer to the box model of CSS, e.g.,
+
+	https://www.w3schools.com/css/css_boxmodel.asp
+
+Example 2.  More Than Just Colors ~
+
+GTK+ CSS supports gradients as well: >
+
+	tooltip {
+	    background-image: -gtk-gradient(linear,
+					    0 0, 0 1,
+					    color-stop(0, #344752),
+					    color-stop(0.5, #546772),
+					    color-stop(1, #243742));
+	}
+
+	tooltip label {
+	    color: #f3f3f3;
+	}
+<
+Gradients can be used to make a GUI element visually distinguishable from
+others without relying on high contrast. Accordingly, effective use of them is
+a useful technique to give a theme a sense of unity in color and luminance.
+
+Note: Theming can be difficult since it must make every application look
+equally good; making a single application more charming often gets others
+unexpectedly less attractive or even deteriorates their usability.  Keep this
+in mind always when you try improving a theme.

+1. Basic use						*terminal-use*
+
+This feature is for running a terminal emulator in a Vim window.  A job can be
+started connected to the terminal emulator. For example, to run a shell: >
+     :term bash
+
+Or to run a debugger: >
+     :term gdb vim
+
+The job runs asynchronously from Vim, the window will be updated to show
+output from the job, also  while editing in any other window.
+
+When the keyboard focus is in the terminal window, typed keys will be send to
+the job.  This uses a pty when possible.
+
+Navigate between windows with CTRL-W commands (and mouse).
+E.g. CTRL-W CTRL-W moves focus to the next window.
+
+See option 'termkey' for specifying the key that precedes a Vim command.
+Default is CTRL-W.

+See option 'termsize' for controlling the size of the terminal window.
+(TODO: scrolling when the terminal is larger than the window)
+
+Syntax ~
+						*:ter* *:terminal*
+:terminal[!] [command]	Open a new terminal window.
+
+			If [command] is provided run it as a job and connect
+			the input and output to the terminal.
+			If [command] is not given the 'shell' option is used.
+
+			A new buffer will be created, using [command] or
+			'shell' as the name.  If a buffer by this name already
+			exists a number is added in parenthesis.
+			E.g. if "gdb" exists the second terminal buffer will
+			use "gdb (1)".
+
+			The window can be closed, in which case the buffer
+			becomes hidden.  The command will not be stopped.  The
+			`:buffer` command can be used to turn the current
+			window into a terminal window, using the existing
+			buffer.  If there are unsaved changes this fails, use
+			! to force, as usual.
+
+Resizing ~
+
+The size of the terminal can be in one of three modes:
+
+1. The 'termsize' option is empty: The terminal size follows the window size.
+   The minimal size is 2 screen lines with 10 cells.
+
+2. The 'termsize' option is "rows*cols", where "rows" is the minimal number of
+   screen rows and "cols" is the minial number of cells.
+
+3. The 'termsize' option is "rowsXcols" (where the x is upper or lower case).
+   The terminal size is fixed to the specified number of screen lines and
+   cells.  If the window is bigger there will be unused empty space.
+
+If the window is smaller than the terminal size, only part of the terminal can
+be seen (the lower-left part).
+
+The |term_getsize()| function can be used to get the current size of the
+terminal.  |term_setsize()| can be used only when in the first or second mode,
+not when 'termsize' is "rowsXcols".
+
+==============================================================================
+2. Remote testing					*terminal-testing*
+
+Most Vim tests execute a script inside Vim.  For some tests this does not
+work, running the test interferes with the code being tested.  To avoid this
+Vim is executed in a terminal window.  The test sends keystrokes to it and
+inspects the resulting screen state.
+
+Functions ~
+
+term_sendkeys()		send keystrokes to a terminal
+term_wait()		wait for screen to be updated
+term_scrape()		inspect terminal screen
+
+
+==============================================================================
+3. Debugging					*terminal-debug*
+
+The Terminal debugging plugin can be used to debug a program with gdb and view
+the source code in a Vim window. For example: >
+
+	:TermDebug vim
+
+This opens three windows:
+- A terminal window in which "gdb vim" is executed.  Here you can directly
+  interact with gdb.
+- A terminal window for the executed program.  When "run" is used in gdb the
+  program I/O will happen in this window, so that it does not interfere with
+  controlling gdb.
+- A normal Vim window used to show the source code.  When gdb jumps to a
+  source file location this window will display the code, if possible.  Values
+  of variables can be inspected, breakpoints set and cleared, etc.
+
+This uses two terminal windows.  To open the gdb window: >
+	:term gdb [arguments]
+To open the terminal to run the tested program |term_open()| is used.

+ * 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 this 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.
