/**
 * @defgroup theming Theming documentation
 *
 * It is possible to theme every aspect of privatemsg with theme functions.
 *
 * For the thread list, so called theme patterns are used to allow flexible
 * theming of the table and its columns (including columns added by other
 * modules).
 *
 * Three requirements have to be fulfilled so a new column, with data, is
 * displayed in the private message list:
 *  - A field needs to be returned by the list query, see @link sql Query Builder @endlink.
 *  - A header theme pattern needs to exist for the field.
 *  - A field theme pattern needs to exist for the field.
 *
 * For each field in the query, Privatemsg will try to call a theme pattern for
 * the header. That theme function can return a table header definition and
 * has the following structure: theme_privatemsg_list_header_fieldname.
 * @see theme_privatemsg_list_header()
 *
 * Privatemsg will then do the same for each row, with the field theme pattern.
 * That theme function should return a table field compatible structure, either
 * just a string or an array. The theme function has to have the following
 * name: theme_privatemsg_list_field_fieldname.
 * @see theme_privatemsg_list_field()
 *
 * To override an already existing theme function, use the following structure:
 * themename_privatemsg_list_field_fieldname. It is not necessary to
 * overwrite the header theme function unless that information needs to be
 * changed too.
 *
 * Modules can use the hook_form_alter() hook to alter the data. The form with
 * id "privatemsg_list" will contain the header, raw and themed field data in
 * the following form:
 * @code
 * $form['#headers']['field_name'] = $header // Array with the header definition;
 * $form['#data']['thread_id'] = $data // Raw data of that thread
 * $form['#rows']['thread_id'] = $row // Themed fields of that thread
 * @endcode
 *
 * Note that the information in #data can be used to populate #rows, but it will
 * not be used by the default theme function theme_privatemsg_list().
 *
