/**
 * The #GtkEntry widget is a single line text entry
 * widget. A fairly large set of key bindings are supported
 * by default. If the entered text is longer than the allocation
 * of the widget, the widget will scroll so that the cursor
 * position is visible.
 * 
 * When using an entry for passwords and other sensitive information,
 * it can be put into “password mode” using gtk_entry_set_visibility().
 * In this mode, entered text is displayed using a “invisible” character.
 * By default, GTK+ picks the best invisible character that is available
 * in the current font, but it can be changed with
 * gtk_entry_set_invisible_char(). Since 2.16, GTK+ displays a warning
 * when Caps Lock or input methods might interfere with entering text in
 * a password entry. The warning can be turned off with the
 * #GtkEntry:caps-lock-warning property.
 * 
 * Since 2.16, GtkEntry has the ability to display progress or activity
 * information behind the text. To make an entry display such information,
 * use gtk_entry_set_progress_fraction() or gtk_entry_set_progress_pulse_step().
 * 
 * Additionally, GtkEntry can show icons at either side of the entry. These
 * icons can be activatable by clicking, can be set up as drag source and
 * can have tooltips. To add an icon, use gtk_entry_set_icon_from_gicon() or
 * one of the various other functions that set an icon from a stock id, an
 * icon name or a pixbuf. To trigger an action when the user clicks an icon,
 * connect to the #GtkEntry::icon-press signal. To allow DND operations
 * from an icon, use gtk_entry_set_icon_drag_source(). To set a tooltip on
 * an icon, use gtk_entry_set_icon_tooltip_text() or the corresponding function
 * for markup.
 * 
 * Note that functionality or information that is only available by clicking
 * on an icon in an entry may not be accessible at all to users which are not
 * able to use a mouse or other pointing device. It is therefore recommended
 * that any such functionality should also be available by other means, e.g.
 * via the context menu of the entry.
 *

 * ├── undershoot.left

 * ╰── [window.popup]
 * ]|
 * 
 * GtkEntry has a main node with the name entry. Depending on the properties
 * of the entry, the style classes .read-only and .flat may appear. The style
 * classes .warning and .error may also be used with entries.
 * 
 * When the entry shows icons, it adds subnodes with the name image and the
 * style class .left or .right, depending on where the icon appears.
 * 
 * When the entry has a selection, it adds a subnode with the name selection.
 * 
 * When the entry shows progress, it adds a subnode with the name progress.
 * The node has the style class .pulse when the shown progress is pulsing.
 * 
 * The CSS node for a context menu is added as a subnode below entry as well.
 * 
 * The undershoot nodes are used to draw the underflow indication when content
 * is scrolled out of view. These nodes get the .left and .right style classes
 * added depending on where the indication is drawn.
 * 
 * When touch is used and touch selection handles are shown, they are using
 * CSS nodes with name cursor-handle. They get the .top or .bottom style class
 * depending on where they are shown in relation to the selection. If there is
 * just a single handle for the text cursor, it gets the style class
 * .insertion-cursor.
