/**
 * GtkScrolledWindow is a container that accepts a single child widget, makes
 * that child scrollable using either internally added scrollbars or externally
 * associated adjustments, and optionally draws a frame around the child.
 * 
 * Widgets with native scrolling support, i.e. those whose classes implement the
 * #GtkScrollable interface, are added directly. For other types of widget, the
 * class #GtkViewport acts as an adaptor, giving scrollability to other widgets.
 * GtkScrolledWindow’s implementation of gtk_container_add() intelligently
 * accounts for whether or not the added child is a #GtkScrollable. If it isn’t,
 * #GtkScrolledWindow wraps the child in a #GtkViewport and adds that for you.
 * Therefore, you can just add any child widget and not worry about the details.
 * 
 * If gtk_container_add() has added a #GtkViewport for you, you can remove
 * both your added child widget from the #GtkViewport, and the #GtkViewport
 * from the GtkScrolledWindow, like this:
 * 
 * |[<!-- language="C" -->
 * GtkWidget *scrolled_window = gtk_scrolled_window_new (NULL, NULL);
 * GtkWidget *child_widget = gtk_button_new ();
 * 
 * // GtkButton is not a GtkScrollable, so GtkScrolledWindow will automatically
 * // add a GtkViewport.
 * gtk_container_add (GTK_CONTAINER (scrolled_window),
 * child_widget);
 * 
 * // Either of these will result in child_widget being unparented:
 * gtk_container_remove (GTK_CONTAINER (scrolled_window),
 * child_widget);
 * // or
 * gtk_container_remove (GTK_CONTAINER (scrolled_window),
 * gtk_bin_get_child (GTK_BIN (scrolled_window)));
 * ]|
 * 
 * Unless #GtkScrolledWindow:policy is GTK_POLICY_NEVER or GTK_POLICY_EXTERNAL,
 * GtkScrolledWindow adds internal #GtkScrollbar widgets around its child. The
 * scroll position of the child, and if applicable the scrollbars, is controlled
 * by the #GtkScrolledWindow:hadjustment and #GtkScrolledWindow:vadjustment
 * that are associated with the GtkScrolledWindow. See the docs on #GtkScrollbar
 * for the details, but note that the “step_increment” and “page_increment”
 * fields are only effective if the policy causes scrollbars to be present.
 * 
 * If a GtkScrolledWindow doesn’t behave quite as you would like, or
 * doesn’t have exactly the right layout, it’s very possible to set up
 * your own scrolling with #GtkScrollbar and for example a #GtkGrid.
 * 
 * # Touch support
 * 
 * GtkScrolledWindow has built-in support for touch devices. When a
 * touchscreen is used, swiping will move the scrolled window, and will
 * expose 'kinetic' behavior. This can be turned off with the
 * #GtkScrolledWindow:kinetic-scrolling property if it is undesired.
 * 
 * GtkScrolledWindow also displays visual 'overshoot' indication when
 * the content is pulled beyond the end, and this situation can be
 * captured with the #GtkScrolledWindow::edge-overshot signal.
 * 
 * If no mouse device is present, the scrollbars will overlayed as
 * narrow, auto-hiding indicators over the content. If traditional
 * scrollbars are desired although no mouse is present, this behaviour
 * can be turned off with the #GtkScrolledWindow:overlay-scrolling
 * property.
 * 
 * # CSS nodes
 * 
 * GtkScrolledWindow has a main CSS node with name scrolledwindow.
 * 
 * It uses subnodes with names overshoot and undershoot to
 * draw the overflow and underflow indications. These nodes get
 * the .left, .right, .top or .bottom style class added depending
 * on where the indication is drawn.
 * 
 * GtkScrolledWindow also sets the positional style classes (.left,
 * .right, .top, .bottom) and style classes related to overlay
 * scrolling (.overlay-indicator, .dragging, .hovering) on its scrollbars.
 * 
 * If both scrollbars are visible, the area where they meet is drawn
 * with a subnode named junction.
