[PATCH] gdkwindow: subsurface in gdk_window_get_effective_parent()
When the GtkWidget hierarchy does not match the GdkWindow hierarchy, the
GtkWidget code may find a common ancestor that cannot be found while
traversing the GdkWindow tree using gdk_window_get_effective_parent().
This happens with for example on Wayland, a GtkPopover has another
GtkPopover as parent, in this case, the GdkWindow parent is the root
window, whereas the GtkWidget parent is the other GtkPopover.
That confuses the gtk_widget_translate_coordinates() logic which will
bail out in this case and won't return the translated coordinates.
Make gdk_window_get_effective_parent() aware of subsurfaces and use the
transient_for which represents the actual parent (whereas the parent
might be pointing to the root window).
