    Fix off by one in check for GtkRoundedBox containing a rectangle
    
    When checking if a rectangle is contained by the rounded box, the code
    will refuse a rectangle which is the exact size as the one backing the
    rounded box, since it checks for greater or equal width and height.
    Check for greater only instead.
