<pre>Description:
When using the Wayland GDK backend, setting an opaque region (with
gdk_window_set_opaque_region()) or an input shape (with
gdk_window_input_shape_combine_region()) has no effect without
begin_paint()/end_paint().
Reason for this is the actual input_region and opaque_region are set/sync'ed
only from gdk_window_impl_wayland_end_paint().
If the caller is not using begin_paint()/end_paint(), the input_shape and
opaque_region are not applied.
This is a difference with the other backends such as x11 where the input_shape
and opaque_region are applied as soon as set with
gdk_window_set_opaque_region() and gdk_window_input_shape_combine_region()</pre>
