    Replace pixbuf.scale_simple statement
    
    When the board is made large the blocks can look blurred due to
    scaling with scale_simple. I replaced this with
    Rsvg.pixbuf_from_file_at_size and the blocks look sharper.
    There are some deprecation warnings so this may need changing again
    to use cairo.
