    core: Make META_CORE_GET_FRAME_RECT return the "frame rect"
    
    We have two different coordinate spaces here. One is the rectangle
    returned by meta_window_get_frame_rect, which is called the "frame
    rect" or "the window geometry", which includes visible frame borders
    but not invisible frame borders. The other is "frame->rect" which
    corresponds to the frame's server geometry. That is, it includes
    both visible and invisible frame borders.
    
    These two were of course the same until we introduced invisible
    frame borders, and an executive decision was made to make
    meta_window_get_frame_rect return the rectangle bounding the
    visible portions of the frame.
    
    As time went on, the "frame rect" turned out to be more useful when
    making decisions upon, since the user often doesn't think about the
    invisible window geometry as part of the window.
    
    We already calculate what amounts to the "frame rect" in the theme
    code, so just change META_CORE_GET_FRAME_RECT to consume that
    directly.
