<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>General: Cast `$max_depth` and `$depth` to an integer in the `Walker` class.
This ensures that the arguments are correctly interpreted when passed as a query string, i.e. when `wp_parse_args()` is involved. For example, `wp_list_pages( 'depth=0' )` should display a list of all pages to the maximum depth.
