/**
* Filter all WordPress queries.
*
* s2Member respects the query var: `suppress_filters`.
* If you need to make a query without it being Filtered, use ``$wp_query->set ('suppress_filters', true);``.
*
* @package s2Member\Queries
* @since 3.5
*
* @attaches-to ``add_action('pre_get_posts');``
*
* @param WP_Query $wp_query Expects ``$wp_query`` by reference, from the Filter.
* @param bool $force Optional. Defaults to false. If true, we bypass all standard conditions.
* However, s2Member will NEVER bypass `supress_filters`.
*
* @todo For improved reliability, modify other query vars associated with exclusions/inclusions. Like `tag_slug__in`?
* See: {@link http://codex.wordpress.org/Class_Reference/WP_Query#Parameters WP_Query#Parameters}
*
* @todo Make it possible to force filtering, even when used in combination with Query Conditionals and ``get_posts()``, which auto-supresses.
* Or, perhaps strengthen the existing ``$force`` parameter in this regard.
