Jasper St. Pierre 8061df1544 gdkwindow-wayland: Obey Wayland buffer semantics 
We can't destroy buffers if they're in-use by the compositor. Well,
technically we can, but that is considered undefined by Wayland and
mutter won't cope with it very well -- it simply kills the client.

To solve this, we need to delay the destroy operation until the
compositor tells us that it's released the buffer. To do this, hold
an extra ref on the cairo surface as long as the surface is in-use
by the compositor.

* 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
* process. In this case the underlying surface isn't an xdg_shell
* 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:
