Comment (by filosofo):

 If the post categories are set, they are passed to wp_insert_post_data.
 Do something like this to access them:

 {{{
 add_filter('wp_insert_post_data', 'my_filter_callback', 10, 2);
 function my_filter_callback($data = null, $arguments = null) {

 // if they're defined, the categories are $arguments['post_category'];
 // tags would be $arguments['tags_input'];


 return $data;
 }
 }}}

 However, that will allow you to change only core post data, not the
 categories or tags themselves.  To do that, use the "wp_insert_post"
 filter.
