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.
