/**
 * GtkStyleContext is an object that stores styling information affecting
 * a widget defined by GtkWidgetPath.
 *
 * In order to construct the final style information, GtkStyleContext
 * queries information from all attached GtkStyleProviders. Style providers
 * can be either attached explicitly to the context through
 * gtk_style_context_add_provider(), or to the screen through
 * gtk_style_context_add_provider_for_screen(). The resulting style is a
 * combination of all providers' information in priority order.
 *
 * For GTK+ widgets, any GtkStyleContext returned by
 * gtk_widget_get_style_context() will already have a GtkWidgetPath, a
 * GdkScreen and RTL/LTR information set. The style context will be also
 * updated automatically if any of these settings change on the widget.
 *
 * If you are using the theming layer standalone, you will need to set a
 * widget path and a screen yourself to the created style context through
 * gtk_style_context_set_path() and gtk_style_context_set_screen(), as well
 * as updating the context yourself using gtk_style_context_invalidate()
 * whenever any of the conditions change, such as a change in the
 * "gtk-theme-name" setting or a hierarchy change in the rendered
 * widget.
 *
 * Transition animations
 *
 * GtkStyleContext has built-in support for state change transitions.
 * Note that these animations respect the "gtk-enable-animations"
 * setting.
 *
 * For simple widgets where state changes affect the whole widget area,
 * calling gtk_style_context_notify_state_change() with a NULL region
 * is sufficient to trigger the transition animation. And GTK+ already
 * does that when gtk_widget_set_state() or gtk_widget_set_state_flags()
 * are called.
 *
 * If a widget needs to declare several animatable regions (i.e. not
 * affecting the whole widget area), its "draw" signal handler
 * needs to wrap the render operations for the different regions with
 * calls to gtk_style_context_push_animatable_region() and
 * gtk_style_context_pop_animatable_region(). These functions take an
 * identifier for the region which must be unique within the style context.
 * For simple widgets with a fixed set of animatable regions, using an
 * enumeration works well:
 *
 * $(DDOC_COMMENT example)
 *
 * For complex widgets with an arbitrary number of animatable regions, it
 * is up to the implementation to come up with a way to uniquely identify
 * each animatable region. Using pointers to internal structs is one way
 * to achieve this:
 *
 * $(DDOC_COMMENT example)
 *
 * The widget also needs to notify the style context about a state change
 * for a given animatable region so the animation is triggered.
 *
 * $(DDOC_COMMENT example)
 *
 * gtk_style_context_notify_state_change() accepts NULL region IDs as a
 * special value, in this case, the whole widget area will be updated
 * by the animation.
 *
 * <hr>
 *
 * Style classes and regions
 *
 * Widgets can add style classes to their context, which can be used
 * to associate different styles by class (see the section called “Selectors”). Theme engines can also use style classes to vary their
 * rendering. GTK+ has a number of predefined style classes:
 * GTK_STYLE_CLASS_CELL,
 * GTK_STYLE_CLASS_ENTRY,
 * GTK_STYLE_CLASS_BUTTON,
 * GTK_STYLE_CLASS_COMBOBOX_ENTRY,
 * GTK_STYLE_CLASS_CALENDAR,
 * GTK_STYLE_CLASS_SLIDER,
 * GTK_STYLE_CLASS_BACKGROUND,
 * GTK_STYLE_CLASS_RUBBERBAND,
 * GTK_STYLE_CLASS_TOOLTIP,
 * GTK_STYLE_CLASS_MENU,
 * GTK_STYLE_CLASS_MENUBAR,
 * GTK_STYLE_CLASS_MENUITEM,
 * GTK_STYLE_CLASS_TOOLBAR,
 * GTK_STYLE_CLASS_PRIMARY_TOOLBAR,
 * GTK_STYLE_CLASS_INLINE_TOOLBAR,
 * GTK_STYLE_CLASS_RADIO,
 * GTK_STYLE_CLASS_CHECK,
 * GTK_STYLE_CLASS_TROUGH,
 * GTK_STYLE_CLASS_SCROLLBAR,
 * GTK_STYLE_CLASS_SCALE,
 * GTK_STYLE_CLASS_SCALE_HAS_MARKS_ABOVE,
 * GTK_STYLE_CLASS_SCALE_HAS_MARKS_BELOW,
 * GTK_STYLE_CLASS_HEADER,
 * GTK_STYLE_CLASS_ACCELERATOR,
 * GTK_STYLE_CLASS_GRIP,
 * GTK_STYLE_CLASS_DOCK,
 * GTK_STYLE_CLASS_PROGRESSBAR,
 * GTK_STYLE_CLASS_SPINNER,
 * GTK_STYLE_CLASS_EXPANDER,
 * GTK_STYLE_CLASS_SPINBUTTON,
 * GTK_STYLE_CLASS_NOTEBOOK,
 * GTK_STYLE_CLASS_VIEW,
 * GTK_STYLE_CLASS_SIDEBAR,
 * GTK_STYLE_CLASS_IMAGE,
 * GTK_STYLE_CLASS_HIGHLIGHT,
 * GTK_STYLE_CLASS_FRAME,
 * GTK_STYLE_CLASS_DND,
 * GTK_STYLE_CLASS_PANE_SEPARATOR,
 * GTK_STYLE_CLASS_SEPARATOR,
 * GTK_STYLE_CLASS_INFO,
 * GTK_STYLE_CLASS_WARNING,
 * GTK_STYLE_CLASS_QUESTION,
 * GTK_STYLE_CLASS_ERROR,
 * GTK_STYLE_CLASS_HORIZONTAL,
 * GTK_STYLE_CLASS_VERTICAL,
 * GTK_STYLE_CLASS_TOP,
 * GTK_STYLE_CLASS_BOTTOM,
 * GTK_STYLE_CLASS_LEFT,
 * GTK_STYLE_CLASS_RIGHT,
 *
 * Widgets can also add regions with flags to their context.
 * The regions used by GTK+ widgets are:
 *
 * Region
 * Flags
 * Macro
 * Used by
 *
 * row
 * even, odd
 * GTK_STYLE_REGION_ROW
 * GtkTreeView
 *
 * column
 * first, last, sorted
 * GTK_STYLE_REGION_COLUMN
 * GtkTreeView
 *
 * column-header
 *
 * GTK_STYLE_REGION_COLUMN_HEADER
 *
 * tab
 * even, odd, first, last
 * GTK_STYLE_REGION_TAB
 * GtkNotebook
 *
 * <hr>
 *
 * Custom styling in UI libraries and applications
 *
 * If you are developing a library with custom GtkWidgets that
 * render differently than standard components, you may need to add a
 * GtkStyleProvider yourself with the GTK_STYLE_PROVIDER_PRIORITY_FALLBACK
 * priority, either a GtkCssProvider or a custom object implementing the
 * GtkStyleProvider interface. This way theming engines may still attempt
 * to style your UI elements in a different way if needed so.
 *
 * If you are using custom styling on an applications, you probably want then
 * to make your style information prevail to the theme's, so you must use
 * a GtkStyleProvider with the GTK_STYLE_PROVIDER_PRIORITY_APPLICATION
 * priority, keep in mind that the user settings in
 * XDG_CONFIG_HOME/gtk-3.0/gtk.css will
 * still take precedence over your changes, as it uses the
 * GTK_STYLE_PROVIDER_PRIORITY_USER priority.
 *
 * If a custom theming engine is needed, you probably want to implement a
 * GtkStyleProvider yourself so it points to your GtkThemingEngine
 * implementation, as GtkCssProvider uses gtk_theming_engine_load()
 * which loads the theming engine module from the standard paths.
