    wayland: Apply states without needing a newly attached buffer
    
    Applying some states, such as the minimum and maximum toplevel size, do not
    require a new buffer and can operate on the old buffer. Requiring a client
    to commit a new buffer just to change such states prevents setting limits
    on an already existing surface buffer.
