Christian Hergert f8e7ecfde1 window: use GtkNative API to update opaque region 
This switches to using the new GtkNative machinery for updating the
opaque region. Some amount of local calculation is still required for
determining when we should apply shadows, and this inherits what was
done previous for that.

/**
* GtkWindow:
*
* A `GtkWindow` is a toplevel window which can contain other widgets.
*
* ![An example GtkWindow](window.png)
*
* Windows normally have decorations that are under the control
* of the windowing system and allow the user to manipulate the window
* (resize it, move it, close it,...).
*
* # GtkWindow as GtkBuildable
*
* The `GtkWindow` implementation of the [iface@Gtk.Buildable] interface supports
* setting a child as the titlebar by specifying “titlebar” as the “type”
* attribute of a <child> element.
*
* # CSS nodes
*
* ```
* window.background [.csd / .solid-csd / .ssd] [.maximized / .fullscreen / .tiled]
* ├── <child>
* ╰── <titlebar child>.titlebar [.default-decoration]
* ```
*
* `GtkWindow` has a main CSS node with name window and style class .background.
*
* Style classes that are typically used with the main CSS node are .csd (when
* client-side decorations are in use), .solid-csd (for client-side decorations
* without invisible borders), .ssd (used by mutter when rendering server-side
* decorations). GtkWindow also represents window states with the following
* style classes on the main node: .maximized, .fullscreen, .tiled (when supported,
* also .tiled-top, .tiled-left, .tiled-right, .tiled-bottom).
*
* `GtkWindow` subclasses often add their own discriminating style classes,
* such as .dialog, .popup or .tooltip.
*
* Generally, some CSS properties don't make sense on the toplevel window node,
* such as margins or padding. When client-side decorations without invisible
* borders are in use (i.e. the .solid-csd style class is added to the
* main window node), the CSS border of the toplevel window is used for
* resize drags. In the .csd case, the shadow area outside of the window
* can be used to resize it.
*
* `GtkWindow` adds the .titlebar and .default-decoration style classes to the
* widget that is added as a titlebar child.
*
* # Accessibility
*
* `GtkWindow` uses the %GTK_ACCESSIBLE_ROLE_WINDOW role.
*
* # Actions
*
* `GtkWindow` defines a set of built-in actions:
* - `default.activate`: Activate the default widget.
* - `window.minimize`: Minimize the window.
* - `window.toggle-maximized`: Maximize or restore the window.
* - `window.close`: Close the window.

*
* The default size of a window only affects the first time a window is
* shown; if a window is hidden and re-shown, it will remember the size
* it had prior to hiding, rather than using the default size.
*
* Windows can’t actually be 0x0 in size, they must be at least 1x1, but
