GtkWindow: Get the correct shadow width even before window is realized

Browse Source 
The window state 'client_decorated' will only be set the window is being
realized. If anyone tries to get the shadow size before that it'd get
the with as if there always was no shadow.

This avoids negative sized opaque regions caused by the allocation being
smaller than shadow.
