    windowManager: Unminimize a window to its buffer rect geometry
    
    If you slow down the unminimize animation you will notice it overshoots and
    then snaps back, but only for decorated windows. Undecorated windows would
    unminimize to their correct position. So we remove decorations from the
    equation and now all window types unminimize to their correct position.
    
    This wasn't noticeable because the unminimize animation velocity is usually
    so high at the end (EASE_IN_EXPO) that there are no frames rendered near the
    end of the curve to show it had overshot.
    
    This appears to be consistent with the Mutter source - associating the
    actor geometry with `buffer_rect` and not `frame_rect`. See
    `meta_window_actor_sync_actor_geometry` for example.
