+/**
+ * Modify the workshop post type archive query to prioritize workshops in the user's locale.
+ *
+ * In order to show all workshops, but with the ones that are presented/captioned in the user's locale shown first, we
+ * need to modify the posts query in ways that can't be done through the WP_Query or WP_Meta_Query APIs. Instead, here,
+ * we're filtering the individual clauses of the query to add the pieces we need.
+ *
+ * Examples, slightly truncated for simplicity:
+ *
+ * Before:
+ * SELECT SQL_CALC_FOUND_ROWS wp_posts.ID
+ * FROM wp_posts
+ * WHERE 1=1
+ * AND wp_posts.post_type = 'wporg_workshop'
+ * ORDER BY wp_posts.post_date DESC
+ *
+ * After:
+ * SELECT SQL_CALC_FOUND_ROWS wp_posts.*,
+ *   MAX( IF( pmeta.meta_key = 'video_language' AND pmeta.meta_value LIKE 'art_%', 1, 0 ) ) AS has_language,
+ *   MAX( IF( pmeta.meta_key = 'video_caption_language' AND pmeta.meta_value LIKE 'art_%', 1, 0 ) ) AS has_caption
+ * FROM wp_posts
+ * INNER JOIN wp_postmeta pmeta ON ( wp_posts.ID = pmeta.post_id )
+ * WHERE 1=1
+ * AND wp_posts.post_type = 'wporg_workshop'
+ * GROUP BY wp_posts.ID
+ * ORDER BY has_language DESC, has_caption DESC, wp_posts.post_date DESC
+ *
+ * @param array    $clauses
+ * @param WP_Query $query
+ *
+ * @return array
