Carlos Garnacho 44c412ecc7 wayland: Pass shadow width to the compositor 
Use xdg_surface_set_window_geometry() to tell the compositor about the
shadow widths, this makes some gnome-shell/mutter features (edge resistance,
frames around windows in the overview, side maximization, ...) work alright
with GTK+.

In order to add this, some other places in gdkwindow-wayland had to gain
some knowledge about margins:

- xdg_surface_configure() now syncs the shadow after applying the state,
  and gdk_wayland_window_set_shadow_width() possibly reconfigures the
  window in order to preserve window geometry. This is necessary to keep
  shadows in sync with state/geometry changes, as this does not happen
  all at once.
- xdg_popups relative to an xdg_surface are shown relative to buffer
  coordinates, so the left/top margins must be added there.

* gdk_wayland_window_get_fake_root_coords:
* @window: A #GdkWindow
* @x_out: (out): The X offset of this window
* @y_out: (out): The Y offset of this window
*
* Wayland does not have a global coordinate space shared between
* surfaces. In fact, for regular toplevels, we have no idea where
* our surfaces are positioned, relatively.
*
* However, there are some cases like popups and subsurfaces where
* we do have some amount of control over the placement of our
* window, and we can semi-accurately control the x/y position of
* these windows, if they are relative to another surface.
*
* GTK+ loves to position "relative" popups like menus in root
* window coordinates, since it was built for display servers that
* have queryable absolute coordinate spaces. In these cases, GTK+
* might ask for the root coordinates of a widget window, add a
* few values, and then call gdk_window_move() with that absolute
* value.
*
* In Wayland, we have to "reverse-engineer" this use, and figure
* out the root coordinates from the relative position, and the
* relative position from the root coordinates.
*
* We invent a coordinate space called the "fake root coordinate"
* space in which a toplevel is always at 0,0, and all popups are
* relative to that space.
*
* gdk_wayland_window_get_fake_root_coords() gives you the
* position of a #GdkWindow in "fake root" coordinates.

* Marks a #GdkWindow as a custom Wayland surface. The application is

* some Wayland interface.
*
* A good example would be writing a panel or on-screen-keyboard as an
* out-of-process helper - as opposed to having those in the compositor

* surface and the panel or OSK client need to identify the wl_surface
* as a panel or OSK to the compositor. The assumption is that the
* compositor will expose a private interface to the special client
* that lets the client identify the wl_surface as a panel or such.
*

* best done by connecting to the #GtkWidget::realize signal:
