    Add some tests for GtkWindow
    
    These tests may have some assumptions on reasonable window manager
    behaviour.  For now, we just test that the default size of the
    window ends up as the allocated size of the content. This test
    currently fails with client-side decorations, because we are
    not properly discriminating between overall window size and
    content size.
