/**
 * GtkScrollable is an interface that is implemented by widgets with native
 * scrolling ability.
 *
 * To implement this interface you should override the
 * "hadjustment" and "vadjustment" properties.
 *
 * Creating a scrollable widget
 *
 * All scrollable widgets should do the following.
 *
 *  When a parent widget sets the scrollable child widget's adjustments, the widget should populate the adjustments'
 *  "lower", "upper",
 *  "step-increment", "page-increment" and
 *  "page-size" properties and connect to the
 *  "value-changed" signal.
 *
 *  Because its preferred size is the size for a fully expanded widget,
 *  the scrollable widget must be able to cope with underallocations.
 *  This means that it must accept any value passed to its
 *  GtkWidgetClass.size_allocate() function.
 *
 *  When the parent allocates space to the scrollable child widget, the widget should update
 *  the adjustments' properties with new values.
 *
 *  When any of the adjustments emits the "value-changed" signal,
 *  the scrollable widget should scroll its contents.
