Theme function for views_slideshow_pager_field_item doesn't accept $view parameter

Issue Summary

Is there a reason why the parameters array for theme('views_slideshow_pager_field_item') doesn't include $view? I want to use the $view->result property to wrap every 3 pager items in a div element, but am unable to get the total number of results in this theme function. I imagine having the view information here would be beneficial, and since views_slideshow_pager_field_field has it, it probably can't have too much of a performance impact.

Is there another way to get the result count of the current view in this theme function, or load the view in its current state by vss_id or something?
